13373⁄4 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention generally relates to the choice of path selection, but by way of example but not limitation, for the purpose of a network gateway _ use path selection, provided from the host The hint of path selection for path selection of the network path [Prior Art] The ability to communicate over the Internet has been significantly affected by the capabilities of the Internet. Use packets to enable information to be easily and easily communicated between two people or other entities. The Internet includes the points that are connected together, so it is possible to transfer packets between them and between them. Some network nodes may be routers from one link to another, others may be individual client computers, others are also personal networks (for example, as special entities), and so on. The Internet spanning between the first entity and the second entity is implemented by a connection constructed between them. These connections are connected. Establish a chat connection to provide a ring communication for this communication to occur on this corresponding connection or on one connection. The establishment of a connection involves a one-way exchange of information between the first and second entities. Usually the complexity of the establishment phase of a conversational connection and the type of conversational connection. - The establishment of each conversation connection utilizes processing resources and cancellations, which translates into a delay time experienced by the user. In particular, such a road facilitates the intercommunication of the internal Internet speed and the relative network section information, or the communication of the whole road involves the intersection, which is usually a conversation or a two-way continuous time spent talking. After the establishment phase of the 5 133-783⁄43⁄4 1. 〇5 line, the first and second entities communicate according to the established intersection environment. Communication and connections may stop but the connection is not terminated. In some cases, when an existing chat connection remains in the previously exchanged information between the two, the existing chat connection can then be used to communicate before the two entities during the setup phase of the previous chat connection. News. In other words, use this previously exchanged information to continue this existing route. Thus, having an existing conversation connection continue is generally the case where the same first and second representations of the conversation connection previously established continue. Thus, if the second entity is unknown and/or difficult to confirm, then the problem can emerge when the first entity tries to keep the existing conversation connection. Thus, there is a need for improvement and simplification of planning and/or technology; facilitating the continuation of a conversation between two entities. SUMMARY OF THE INVENTION In a first exemplary media implementation, one or more processor-storable media includes processor-executable instructions that, when executed, direct a loaded execution action including: using a host identifier to generate a Talk to the line character; and use the generated chat connection identifier to formulate an initial message for a host conversation.

[Embodiment] FIG. 1 is an exemplary communication environment 100 illustrating a first connection 1 1 4 (1) establishing a conversation connection and a second connection 114 (2) continuing the conversation connection. As illustrated, the exemplary communication environment 100 includes a plurality of clients 102(1), 102(2)..102(m) and a plurality of hosts 108(1), 108(2)...108(n) ), as well as a network 104 and a network gateway (NG) 106. The gateway gateway 1 0 6 acts as a gateway between the network 1 0 4 and an internal network 1 10 . The host 1 0 8 is coupled to the internal network channel 1 1 0. In a described implementation, clients 102(1), 102(2)...1 02(m) respectively correspond to the addresses "Cl", "C2",..."Cm" . Each client 102 may be any device capable of network communication, such as a computer, a mobile station, an entertainment device, another network, and the like. Client 102 may also correspond to a person or other entity that is operating a client device. In other words, client 102 may contain a logical client that is a user and/or machine. Network 104 may be formed from one or more networks, such as the Internet, another internal network, a wired or wireless telephone network, a wireless broadband network, and the like. Referring to Figure 8, an example of an add-on for the client 102 and an example of the type/topology for the additional network of the network 104 are described below. The individual client 102 can communicate with one or more hosts 108 13378822 96. 1. - I · i * - . 1 ··*··> · the letter, and vice versa, via the network gateway 1 0 6 Cross the network 1 0 4. The hosts 108(1), 108(2).·.108(η) correspond to the addresses "Η 1 ”, " Η 2 ”...” Η η ”, respectively. The host address Η 1, Η 2 ... Η η appears on the internal network 110. The general host 108 hosts one or more applications (not shown). These applications (i) provide services to interact and/or communicate with the client 102, (ii) let the client 102 use, and the like. By way of example only, such applications may include file transfer programs, web management/server programs, remote access programs, email programs, data repository programs, and the like. Each host 108 may correspond to a server and/or a device, a plurality of servers and/or a plurality of devices, a portion of a server and/or a portion of a device, some combination thereof, and the like. Referring to Figures 2, 4 and 5, a particular exemplary implementation for host 108 is further described below. Further, with reference to Fig. 8, an implementation of an additional exemplary apparatus for the host 108 will be described below. The network gateway 106 is at one or more addresses "NGN" is reachable or addressable via the network 104, and the network gateway 106 is also present on the intranet with at least one address "NG I" On line 11 0, communication is received at the gateway 1 〇 6 from the client 102 (or other node) of the address NGI of the gateway gateway 106, and thereafter the route is selected to the host 108 (1) A host 10 of 108(2) ... 108(n) 8. The network gateway 106 includes one or more network gateway elements (not separately shown in Figure 1). Each network gateway component 106 may include all routers or a portion of a router, a proxy/host, a load balancer, a firewall device, some of these combinations, etc. 9 1. 0 5 pairs An exemplary non-specific device implementation of network gateway 106 is also described below with reference to Figure 8. In general, a connection is made between client 102 and host 108 over network gateway 106 via network gateway 106. 114. Usually client 102 initially connects 114, however, host 1〇8 may be another initiator.

In this example, client 102(1) initiates a connection 114(1) containing host 108(2). However, for address H2 of host 108(2), client 102(1) is not private. Instead, the client i〇2(i) directs the connection to the address NGN of the network gateway 106 (e.g., a packet requesting a connection).

At this time, the network gateway 1 〇 6 performs a path selection operation 丨 16(1) on the connection 1 14(1) according to some preset policy (for example, a rule). As a result, in this example, the network gateway 1 〇 6 makes a path selection connection 114(1) to the host 1〇8(2) on the internal network. In general, the network gateway 1〇6 cannot send the packet of the connection 114 from the client 102(1) to the host 108(2) at the network address H2 because these packets are destination addresses to the network gate. The address of the channel 1〇6 is NGN. Instead, the network gateway 一般 6 typically uses one or more of the following exemplary choices to specify a transmission path for the packet across the internal network 11: URL translation (NAT), one-way URL conversion (half NAT), tunneling techniques (tunneling), some combination of them, and so on. In a Transmission Control Protocol/Internet Protocol (TCp/Ip) environment, URL translation (NAT) is performed by (i) rewriting the source of this source (ie, client 1〇2(1)). The tamper (丨丨) of the network gateway 106 generated by the nickname and the URL conversion with the ip address NGI is rewritten by rewriting the destination IP address NGN containing the IP address H2 of the host 108(2). The one-way URL conversion (halfNAT) is performed by rewriting the destination IP address NGN containing the IP address H2 of the page host 10 08 (2), so the source IP address C1 and the number are reserved. . The wearer technology (tunneHng) is packaged by a new IP packet pointing to the IP address H2 of the host 108(2), and the packaged packet is transmitted from the network gateway 1〇6 to Host 108(2), which is where the packet can be unwrapped.

A talk connection is established between client 102 (丨) and host 108 (2) during connection 114(1). For the chat connection established by the connection 1 1 4( 1 ), a chat connection environment n2 is generated at the host 108(2). A similar, similar, and/or reciprocal conversational connection environment (not shown) is also typically generated at the client 1 0 2 (1). A chat connection environment 112 causes the client to 丨02. Communication with the host 108(2) is convenient.

Thus, connection 114(1) may or may have been established on any one or more of many different types of conversation links. The congratulations of the conversational connection include: (1) a secure encrypted socket layer (SSL) conversation connection; (ii) a transport layer security (TLS) conversation connection; (iii) an internet security Protocol (IPsec) conversation connection; (iv) - Hypertext Transfer Protocol (HTTP) authentication mode (cookie-based) conversation connection; (v) - Point-to-point Path Protocol (PPTP) conversation connection (vi) - Internet Security Protocol (IPsec) / Layer 2 Tunneling Protocol (L2TP) conversation connection; (vii) - exclusive conversation connection; (viii) - terminal server chat connection ;(ix)—talking lines defined by the manager; (X) and so on. This example of different conversation connection types also establishes how layers of conversational connections may be established and used. The content of a conversation connection environment 1 1 2 may vary, at least in part, depending on the type of conversation connection that is generated. For example, a specific conversation connection environment 11 2 11 I33^78_iSivO5---------

May be included in one or more of the following: a transmission control association (for example, a conversation connection established with a TCP connection); an identifier; a location for maintaining a persistent state database login for the corresponding conversation connection; A public key for the client of host 108(2); a private password key that has been negotiated: other parameters; and so on. The 4-tuple of a transmission control protocol includes an address, a source TCP, a destination IP address, and a destination. Under the current standard, the conversation connection to the s SL can be up to 3 in length via the example line identifier. 2 bytes. As in the above, after constructing the 114 (1) connection, in the example, a line is established between the client 102(1) and the host 108(2). More specifically, client 102(1) is establishing an application for at least one application resident and/or clear on host 1 0 8 (2), which is typically possible when referring to host 108(2). The stage of conversational connection creation creates or causes a conversation i 1 1 2 . The environment in which the conversation is connected 1 1 2 provides an environment for communication between the client 1 02 ( 1 ) and . Conversation Connection Environment 1 1 2 Communication is actually vital, only beneficial, and informative. Assuming that client 102(1) may be a logical client, environment 11 2 may be related to communication between (i) a particular device and/or a user and (ii) host 108(2). Because the connection environment 1 1 2 is associated with a user client 1 02 (1) can be [: 4-tuple one or more connected to the end 102 (1) Security-related source IP bit TCP埠. For this conversation, the current Li Yi talk link contains 1. However, for an environment host 108(2) that includes such an l-line, it can include a specific device for talking to or talking to the parties concerned, and a conversation can be made from different 12 I3J7&22f

The association continues, even as the user client 102(1) accesses the host 108. This device can be different for client 102(1) at a regional level, at a network 104 level, and so on. Examples of such different device scenarios include a proxy host scenario (e.g., those Internet Service Providers (ISPs)), a terminal server chat connection episode, and the like.

The chat connection environment 112 is stored at the host 108(2) and/or where it can be accessed. When the connection 1 1 4 ( 1) is completed or stopped, the chat connection environment 1 1 2 may no longer be used. Conversely, if the client 102(1) and the host 108 attempt to initiate another connection, for a same, similar, or related, etc. conversation connection, the conversation connection environment 1 1 2 may be again The opposite is useful. If the other connection does not have a path selected to the same host 108(2), it is to store the chat connection environment condition 1 1 2, but the client 102 (1) must establish a new chat connection, which may be time consuming Intensive material/processing, and/or blocking to the user (especially corresponding to a user of client 102(1)). In the network gateway 106, there is no sort of connection affinity relationship mechanism, and there is generally no greater chance of a random chance of selecting the same host 108(2) than the second connection.

A chat connection affinity mechanism or functionality applies to path connections (including the requirements of the upper and logical levels of the packet) back to a host 1 〇 8, which is associated with an existing chat connection that continues the connection A conversation connection environment 1 1 2. For example, the chat connection affinity save functionality for client 102(1) attempts to connect 11 4(2) with path selection back to host 1 08(2), which is associated with chat connection environment 1 1 2 . It is possible to implement such a conversation based on one or more demonstrations. The relationship is closely related to the preservation mechanism. 13 4 m-ma-05------ Years of the year (more), the page is usually applied to the network. Gateway 106, but these exemplary approaches are described from the perspective of a load balancing implementation. The first strategy relates to a balanced load containing a "sticky" pattern, if not all, in that mode from a requirement that the path is selected to the IP address of a single host 108. However, this strategy relies on an assumption. The IP address represents the assumption of a single client 102, but a client 102 is untrue for the proxy host. A proxy host appears to the load balancer as a single IP address, but it actually Representing the requirement for many, potentially thousands, of clients 102. As a result, all of these requirements to a single host 108 specify that the transport path can direct a very unfair load balancing between devices/in the middle of the device. Assigning a very large number of clients 102 to receive requests from one of the proxy hosts. In addition, using this first policy from the request of the client 102 with the changed IP address also incorrectly specifies the delivery. Path. When the address is temporarily configured from the IP address library, etc., the IP address can be changed in a mobile environment. The second strategy involves using a load flat. a heuristic method that uses a chat connection identifier to cause an existing chat connection to continue to the host to specify a transport path that was previously established using this particular individual talk link identifier ( For example, the protocol is connected. In operation, after a particular chat connection is established between a particular client 102 and a particular host 108, a pair of images is stored, the mapping being for a particular conversation. The connection identifier has a connection confirming this conversation and connecting that particular host 1 0 8 to that particular conversation connection. When receiving from that particular client 102 includes 14 I —......... u cold (more) is replacing one of the specific chat connection identifiers required to use this mapping, enabling this request to be returned to that particular host 108 to specify the transmission path. Therefore, this second strategy enables the conversation to be wired. Close relationships can be preserved. However, from an efficiency perspective, the second strategy is accompanied by several relative drawbacks. First, the load balancer maintains a chart of these mappings between the chat connection identifier and the host 1 0 8. The size may be large because there is a separate login for each existing chat connection. For example, if each host 108 stores 10,000 chat connections and has 500 hosts 108, the chart uses 5 million logins. To specify the delivery path with the best efficiency for these conversational connections. Second, for each newly established conversation connection, the load balancer monitors the phase of this chat connection establishment until the conversation connection is detected. Character, and a login can join this chart. Third, each time you receive a request to restore the chat connection, in order to perform this path selection, this negative ¥ + weighing instrument consults this (may be very large) chart. Fourth, because of this The chat connection has a lifetime and is actively retired or evicted from the cache memory of the host 1 0 8 due to extreme congestion. The load balancer chart also implements some old-fashioned mechanisms to reflect the individual host 1 0 8 Doing or expecting to do it with their own cache memory. If the host 108 and the load balancer refinement mechanism are out of sync, the load balancer may prematurely delete the status information for the chat connection, and the chat connection is still valid on the host 1 0 8 or, conversely, this The load balancer may reserve status information for the chat connection, and this chat connection no longer exists at any host 108. Conversation Connections The third strategy of saving functionality enables a conversation connection established for the recent 15 13373⁄43⁄4.os to reach a close connection in the network gateway 10 6 via the selective generation/decision of the conversation connection identifier. The relationship is saved, and no chart needs to be logged in for each individual chat connection. When the chat connection identifier is determined, the host 1 0 8 embeds a host identifier therein.

The network gateway 1 0 6 retrieves a host identifier from a chat connection identifier, and the chat connection identifier is assigned a conversation connection in response to the host identifier as a traffic path selection. Thus, the third strategy can use a relatively stateless method that uses a chart with a limited number of logins to continually negotiate the transmission path (eg, several logins equal to the number of hosts 108) and / Or, instead of using one of the logins with such a chat connection, the conversation is continually stipulated to specify the transmission path. The aspect of this third strategy is further described here.

In the example of the communication environment 1 , , the chat connection environment 1 12 is generated at the host 108 ( 2 ) after the completion of the session connection establishment phase, such as partial connection 1 14 (1). After that, connect 1 14 (1) to stop. When a request for connection 1 14(2) arrives at network gateway 106, a path selection operation 1 1 6(2) is performed thereon. This connection 1 14(2) indicates a continuation of the previously established conversation connection, and a continuation of the previously established conversation connection by the conversation connection identifier assigned to that corresponds to the conversation connection environment 1 1 2. The chat connection identifier includes an identifier of the host 1 08(2) according to the third policy. For the host 1 0 8 (2) retrieved from the conversation connection identifier of the continuation request from this conversation connection, using this host identifier, in the path selection operation 1 1 6 (2), the connection 114 (2) The delivery path is specified to the host 108(2), which is associated with the chat connection environment 112. 16 ___________ Yearly repair (more) replacement page

Items 1 1 4 ( 1 ) and 1 1 4 ( 2 ) may also represent conversational-related messages (eg, requirements) that occur within a single connection and those that occur during two or more connections. Moreover, the particular communication between client 102 and host 108 is described herein as a message. Messages are typically propagated from client 102 to host 108, and vice versa, such as one or more packets. The client message is sent from the client 102 and the host message is sent from the host 108. Conversation connection messages are those related to the conversation connection (for example, those related to the establishment, continuity/recovery, decomposition, etc. of the conversation connection). An exemplary conversation connection message is further described below with reference to Figure 3.

The start message of the chat connection is sent by the client 1 0 2 and/or the host 1 0 8 about starting a chat connection. The continuation message of the chat connection is sent by the client 102 and/or host 108 associated with continuing the existing chat connection. The start message of the chat connection and the continuation of the chat connection may be significantly different, similar formats, identical layouts, and the like. However, in a described implementation, the start message of the chat connection and the continuation message of the chat connection have at least a similar format, wherein the presence of a chat connection identifier indicates that a client chat connection message is a client The continuation message of the conversation connection, and the absence of a conversation connection identifier indicates that a client conversation connection message is the start message of a client conversation connection. While the description herein is not so limited, these are described below as network gateways 106 that occasionally emphasize or focus on load balancing implementations. Similarly, although other agreements and combinations of agreements are applicable and may be used or used, the following description mainly uses TCP/IP (Transmission Control Protocol/Internet Protocol) and SSL/TLS (Safety Plus 17) for the sake of clarity. 13 ----------- Years and months more) Positive + only change page security layer / transport layer security) chat connection. By way of example, but not limitation, the continuation message of a client's chat connection or the continuation of a client's chat connection may be a "client-side Hello" message according to the TLS Protocol Version 1.0 specification (January 1999). If the client Hello message includes a chat connection identifier, it may be a continuation message of the client's chat connection, otherwise it may be the start message of a client's chat connection. Similarly, a host chat connection The start message or the continuation message of a host chat connection may be a "server H e 11 〇" message according to the TLS protocol version 1.0 specification. If the server H e 11 〇 message is included in a client Hello message A chat connection identifier provided by a client, the server H e 11 〇 message is responding to the client H e 11 〇 message, but it may be a continuation message of the host chat connection. If the server H e The 丨1 〇 message responds to the client H e 11 〇 message that does not include a chat connection identifier, but it may be the initial message of a host chat connection. Further description is provided below. A chat connection identifier and an initial message for such a host chat connection. Figure 2 illustrates an exemplary method for providing and using a path selection hint containing a chat connection message. From the client 102 to the host 108 Conversation connection messages 202, 204, and 206, or vice versa, across network 104 via a network gateway component 106. Network gateway component 1 0 6 represents network gateway 1 0 6 (No. 1 Figure). Although each conversation connection message 2 0 2, 204, and 206 is displayed as selected by the network gateway component 106 path, each individual conversation connection message may be by a network gate. Different individual components of lane 106 specify the transmission path. 18 1337822 f' 96. i. ου..........,: -t As illustrated, host 108 includes processing to be sent from client 102 and One of the messages received is a message manager 2 0 8. The message manager 2 0 8 includes an incoming message manager portion 208IC and an outgoing message manager portion 208OG. The host 1 8 is associated with a host identifier 214. It is stored or accessible from the host 108. Refer to Section 3 below for more information. An example of a host identifier 214 is described in one step. The host 108 also includes a chat connection identifier generator 2 1 2 that uses the host 2 1 4 identifier to generate a chat connection identifier (eg, a conversation connection identifier) In the implementation of a description, the client 102 has a bit address "C", and the network gateway component 106 has the address NGN and NGI, including the address C located on the network 104. And NGN. Host 1 具有 8 has an address "H" which is located on the internal network 11 连同 along with the address NGI. The chat connection message from the client 102 is received at the network gateway component 106 via the network 1 〇4. At this time, the network gateway components 1 〇 6 are on the internal network 1 1 , and the path selection operation 2 1 6 specifies that these conversation connection messages are routed to the host 108. In the opposite path, the talkwire message from the host 108 is routed across the internal network 110 to the network gateway component 106, which routes the talkwire message to the client 102 in a path selection operation 216. . In particular, the client 102 sends a start message (SIM> 202) of a client chat connection to the network gateway component 1〇6 on the network 104. The start message 202 of the client chat connection does not include A chat connection identifier, since it includes a requirement as a new chat connection. Because the client chat connection start message 202 is not for an existing chat connection, the network gateway component 106 is in the path selection. At operation 216 (A), the client 19 1917 * 21 year - the repair (more) is replacing the start message of the page chat connection 2 0 2 to specify the transfer path to the host 1 0 8. For example, The network gateway component 106 may, in accordance with a current and/or associated load balancing policy, route the client talk connection initiation message 202 to a delivery path (e.g., a loop of the incoming new conversation connection request). 8 receives the start message 202 of the client chat connection at the incoming message manager part 20 8IC via the internal network 110. Without a chat connection identifier, the incoming message manager part 2 0 8 IC identifies the client The start message of the conversation connection 2 0 2 is a new conversation connection. The conversation connection identifier generator 212 causes a new conversation connection identifier to be generated for one of the new conversation connections required. The conversation connection identifier generator 2 1 2 determines / Retrieving the host identifier 2 1 4 . The chat connection identifier generator 2 1 2 uses the host identifier 2 1 4 to generate the chat connection identifier 2 1 0. For example, the chat connection identifier generator 2 1 2 will The host identifier 2 1 4 is inserted in the chat connection identifier 2 1 0. The chat connection identifier 2 1 0 may also include values other than the host identifier 21 4 . It may be generated using any one or more techniques. This conversation links additional values of the identifier 210. Such techniques include, but are not limited to, a randomly selected value, a value from an up counter, a security related value, a hash value, some combinations thereof In a description of the implementation, the first portion of the chat connection identifier 2 1 0 (i.e., the host identifier 2 1 4) is the host 108 dedicated to confirming that this currently has a corresponding chat connection. The first part is the only one that spans a hypothetical group. The set of these hosts 108 (i.e., no host 108 is sharing its host identifier 2 1 4 with any other host 1 0 8 in the same cluster) » The first part can be 20

It is an IP address owned by the host 108, an integer assigned by a manager, and the like. The second part of the conversation connection identifier 2 1 0 can increase the uniqueness (and unpredictability) of the conversation connection identifier 2 1 0. A number of techniques can be used for this second part, such as using a global count that increments each new conversation connection (with interaction effects to zero) and using pseudorandom and/or hashing techniques. Combination of.

The chat connection identifier generator 2 1 2 provides a chat connection identifier 2 1 0 to the message manager 2 0 8 . The outgoing message manager section 2 0 8 0 G prepares/defines an initial message including the chat connection identifier 2 1 0 of the host chat connection 2 0 4. The initial message 204 of the host talk connection is sent to the network gateway component 1 0 6 on the internal network 1 10 . The network gateway component 106 then uses a wraparound path selection operation 216(B) to send the initial message 206 of the host talk connection to the client 102 on the network 104. Although not exemplified, the initial message 204 of the host talk connection may be bypassed along a path that does not include the network gateway component 106, especially if the network gateway component 106 is not yet stored. - Talk about the status information of the connection and specify the delivery path for the client message. The client 102 retrieves a chat connection identifier 2 1 0 from the initial message 204 of the host chat connection, and is a chat connection that may be used to continue the establishment in the future (and the chat connection established thereby as any current) Use) to keep the chat connection identifier 2 1 0 . At some point, the actual use of the established chat connection is stopped (for example, a connection is terminated). In order to continue the connection with the established and existing conversations with the host 108, the client 102 formulates a continuation message (SCM) 206 for the client's talk connection. The client 102 talks with the client at 21 05· 05. The reserved chat connection identification message 206 is from the continuation message 206 of the client 102 1 0 6 ρ line 6 τ includes the continuation of the client chat connection 1 04 Being sent to the network gateway component when the network gateway component + 106 receives the client chat connection message 2 06, it detects the room Λ, J each terminal 102 is trying to make the existing line continue as thus included $J parent attack line identifier 2 1 0 indicated

In operation 216 (C) selected, the fine A network gateway component 106 uses the identifier 210 to revoke the continuation message 206 of the client chat connection. & In particular, 'the network gateway component 丨〇6 uses the host to recognize the client's conversation, the continuity of the line 4 206 specifies the transmission path identifier 2 1 4 疋 part and recognizes the chorus 2 i 从 from the conversation connection The host identifier 2 1 4 confirms its associated host 1 08. Since the identification of the component 1〇6 using the host 1〇8 is indicated by the host identification, the path selection operation 216(c) specifies the transmission path for the client continuation message 2 0 6 . Therefore, the client handoff message 206 crosses the internal network n from the network gateway element ^ to the host 108. The message manager department in the host 1〇8' receives the continuation message 206 of the client chat connection, and can start the previously established conversation connection state by using the connection environment (for example, 'as in the first 1 The conversation shown in the figure is equivalent to the net production [^ 2 host identifier 2] 4 can be associated with the complex bran bias mode machine 1 08.

In other words, the continuation message of the client chat connection 206 can be forwarded to the host 1 0 8 using the host identifier 2 1 4, or at least part of it, as a client. The continuation message 206 of the end-talk connection is placed on the destination address of one or more packets on the internal network 110.

Alternatively, host identifier 214 can be mapped to host 108 address. Although the pattern of this mapping involves a chart (or a calculation), the number of logins in the chart "η" may be equal to in the server cluster, on the internal network 110, in a web farm. Medium, etc. The number of hosts 108. Therefore, this chart has a limited number of logins and does not include status information for each-talk connection. Referring to the example used above, if each host 108 stores 10,000 chat connections and there are 500 hosts 108, this chart may use 500 logins (instead of 5 million) to efficiently wire these conversations. The delivery path will be required. The following chart 1 is an exemplary link data structure that links the host identifier 2 1 4 to the host 1 0 8 via the address of the host 1 0 8 .

Figure 1 - The data structure used to map the host identifier 2 1 4 to the host address. In operation, the network gateway component 106 retrieves a host identifier from the conversation connection identifier 2 1 Ο of the client's conversation connection 23 13 ---------- continuation message 2 Ο 6 2 1 4 (#), as received from client 1 0 2 . At this point, the network gateway component 106 accesses a linked data structure, such as the data structure of Figure 1, using the host identifier 214(#) to determine the host address Η# linked to this. The host address H# corresponds to the address of the host 108 (#) on the internal network 110, and is used as the destination address to connect the continuation message 206 of the client chat connection to the host 1 0 8 (#) specified transmission path. . An exemplary host identifier-network address connection diagram is further described below with reference to Figures 6 and 6Β.

Figure 3 illustrates an exemplary chat connection message 302 that can include a hint of path selection. The chat connection message 302 is a message related to one or more conversation connections. As illustrated, the chat connection message 3 02 includes a plurality of fields. These plurality of fields include the conversation line identifier 2 1 0 and one or more other fields as indicated by the other fields 304.

The chat connection identifier 2 1 0 includes at least one host identifier 2 1 4 . The host identifier 2 1 4 includes a device identifier 306 and an arbitrarily selectable application identifier 308. Device identifier 306 may include a network address 3 1 0 or a key 3 1 2 (A). Alternatively, host identifier 214 may include a key 312 (B). In a described implementation, a format or a plurality of formats for the chat connection message 302 are defined by a network or communication standard or protocol such as SSL/TLS. The chat connection identifier 2 1 0 may be found anywhere within the chat connection message 03, especially as defined by applicable standards or agreements. Other fields 304 may include a source and/or destination address, general header information, security type information, other chat connection related information, information, some combination of such, and the like. By way of example, the chat link may be a He 11 or a server H e 11 message as defined by the TLS protocol version 1.0 standard, and the chat connection identification can correspond to any TLS (Transport Layer Security) Hello. The "Identifier" field of the message. A password field for the field type 3 0 4 of the security type information indicating that the participant is connected by a conversation connection message (for example, a client or a host) Supporting the selection. The conversation connection identifier 2 1 0 includes the host identifier 2 1 4 into a chatline identifier that can be arbitrarily selected other values. This identifier resides in the chat connection information of the chat connection message 3 0 2 In the field, a host identifier 2 1 4 can be found within a field of the conversation connection identifier 2 1 0, including the divided and scattered cloth in the conversation connection identifier 2 1 0. In an implementation described for ease of retrieval, a contiguous sequence of sub-fields corresponding to the conversation line identifier 2 1 0 of symbol 2 1 4 is implemented. The contiguous sequence of this byte is connected from the conversation. 210 of the most important bytes appear a fixed The difference may be replaced by the least significant byte. For additional flexibility, the host identifier 214 may be set, for example, not by an SSL/TLS element. For example, a registration key by value It is possible to externally configure a host identifier 2. As indicated above, a manager may determine that host identifier 2 sets this registration key value or via some other mechanism. Message 3 0 2 A client symbol 210 can talk to An example of a line is the password of 302 and the connection between the two. The symbol 210 can be used anywhere, and/or the host is recognized as a byte line identifier, and the external can be read as a one. 4. As with 1 4, if the 25 nmm:~ year-end repair (more) is changed, the host identifier 2 1 4 may be embedded in the chat connection field. For example, when an existing one is being requested In time, it is possible to use a specific field sent to a client 102 and return from that < if the message format and the desired conversation connection environment 1 1 2 allow or require a main specific field Generate/select this value, this In particular, the network gateway component 106 performs the path selection operation 216 using the internals of the particular field. The host identifier 2 1 4 includes a device identifier 3 06 an application identifier 308 » device identification A device of one of the hosts 108 associated with the symbol 214, such as the device identifier 3 0 6 containing a network address 3 1 0 or a device that recognizes the host 1 0 8 . Address 3 1 0 is a network address on the internal network 1 1 0 for the device. Therefore, if the device recognizes the network address 3 1 0, a network gateway component 0 6 may be Insert into a packet or number of blocks that are forwarded to host 1 0 8. The key 312(A) is a value that is mapped to a network address of a device in the internal host 108. It is possible to query a network address, perform this calculation by performing a calculation (e.g., as an algorithm, etc.), and the like. Table 1, as described above, the key 3 1 2(A) may be linked to a host address Η. Referring to Figure 6A, in the following, the non-talking connection recovery of the client 102 does not have a protocol of 1 0 8 for this. For at least part of this selection, and possibly including the host identification example, install "312(A), which does include a token of the host 1 08, including a flag: a destination network of 3 0 6 packets. The road 1 1 0 is further described by a formula in a chart, an example, for example, a reference figure to a data structure. 26 1337822 __^ --Qg — ............... ..... 斗>]· 上竹换 u an exemplary diagram in which the key 3 1 2(A) is linked to the network address 3 1 0. When the host identifier 2 1 4 includes a device identification The host identifier 2 1 4 contains an application endpoint when the symbol 3 06 and an application identifier 3 0 8. The application identifier 3 0 8 is confirmed on a host device confirmed by the device identifier 306. a specific application. Therefore, a host identifier 2 1 4 including a device identifier 306 and an application identifier 308 can identify a particular application from a plurality of applications, and a plurality of applications The application is replicated on a single host 108 and/or across a plurality of hosts 108. Includes a device identifier 3 06 but A host identifier 2 14 without an application identifier 3 0 8 may also include an application endpoint. For example, when a device has only one application, when a device belongs to multiple locations, when a device is in a network This is especially true when the Road Information Center (NIC) has two IP addresses, etc. In either case, the host identifier 2 1 4 serves as a confirmation for a particular application and a particular host 108. Thus, The desired application for this purpose may quickly perform a path selection of the continuation message 206 of the client chat connection, and the desired application has a close relationship with the client 102 of the request. Host identifier 214 may also include a key 3 12(B). The key 312(B) is a value that is mapped to (i) one of the devices on the internal network 1 10 to a device of the host 108. Address and (ii) a particular application on top of it. Such mapping enables key 3 1 2 (B) to be mapped to an application endpoint without using a separate application identifier 308. Query a network address / pair in a chart The program identifier is implemented by performing a calculation of 27 1337^2, .05 (for example, according to a formula, implementing an algorithm, etc.), etc. For example, the key 3 1 2 ( B) may be linked to a network address 310 and an application identifier 308 in a data structure. Referring to Figure 6B, an exemplary diagram is further described below in which a key 312(B) is linked to the network. The road address is 3 1 0.

In another alternative implementation, a code may be embedded in one of the talk line identifiers 2 1 0 of the chat connection message 3 0 2 . This code may occupy a partial or entire conversation line identifier of 2 1 0. This code can be used to communicate with information from a host 1 〇 8 to a network gateway component 1 0 6 and/or a client 1 0 2 (eg, data, commands, etc.). Conversation Connection The field of this conversation connection identifier for message 3 0 2 may be in the code itself and/or a conversation connection identifier 2 1 0 generated using this code. After the pairing of this code (eg, a query, a calculation, etc.), the client 10 2 and/or the gateway component 1 0 6 of the network may retrieve the code and utilize the communicated information. As, and so on.

Figure 4 is a flow chart 4 0 0 illustrating one exemplary method for providing a choice of path selection. The process 圊400 includes seven blocks 4 0 2 - 4 1 4. Although the actions of flowchart 400 may be performed in other environments and include various hardware architectures and software plans, Figures 1-3 (and Figure 5) are used to illustrate some aspects and examples of this method. For example, Host 1 〇 8 might perform the actions described here. In block 410, a client talk connection message is received. For example, a host 108 may receive a client chat connection message from the client 102 2 2 2 or 2 0 6 (eg, a message manager 2 0 8 comes in 28 1337 disk side 1 --- ------ Year of the month (more) is the message manager part of the page 208IC). In block 404, it is determined if the received client chat connection message block includes a chat connection identifier. For example, it may be possible to check the received client chat connection message 202 or 206 (eg, in the format of a chat connection message 3 0 2) to determine if it has a conversation in the field of the conversation connection identifier. Line identifier 2 1 0.

If the received client chat connection message includes a chat connection identifier 2 1 0, the received client chat connection message is a continuation message (SCM) 206 of the client chat connection, and this The method continues in block 412. On the other hand, if the received client chat connection message does not include a chat connection identifier 2 1 0, the received client chat connection message is the start message of a client chat connection ( SIM) 202, and the method continues in block 406.

In block 406, a talk link identifier containing a host identifier is generated. For example, a talk line identifier generator 2 1 2 uses a host identifier 2 1 4 of the host 1 0 8 to generate a talk line identifier 2 1 0. The conversation connection identifier generator 2 1 2 may insert the host identifier 2 1 4 into a conversation connection identifier 2 1 0 along with other values. In block 408, the initial message for making a host talk connection contains a chat connection identifier generated. For example, an outgoing message manager portion 2 0 8 Ο G may formulate (eg, using a format such as chat connection message 3 0 2) a host chat connection initial message 204, which includes a host identifier 2 1 4 conversation connection identifier 2 1 0. In block 410, the initial message of the host talk connection is sent. For example, the host 1 0 8 may transmit the initial message 29 of the host chat connection to the client 102 via the network gateway component 106 on the network 104. On the other hand, if it is determined whether the received client chat connection message does include a chat connection identifier (at block 4〇4), then in block 412, the continuation message of the host talk connection includes This received client chat connection identifier. For example, the outgoing message manager portion 2〇8〇G may formulate (eg, use the format of the chat connection message 302) a continuation message of the host chat connection (not specifically shown in FIG. 2) The received conversation line identifier 2 1 0 (possibly including a previously embedded host identifier 2 1 4). A continuation message for this host chat connection is sent in block 4 1 4 '. For example, 'Host 1 〇 8 may pass a continuation message of a host chat connection to the client 1 〇 2 on the network 1 〇 4 via the network gateway component i 〇 6 » Figure 5 illustrates another exemplary method Use the chat connection message to provide and use hints about path selection. This exemplary method focuses on the hint of using path selection in a network gateway, component 1 0 6 . As illustrated, the clients 102 (1), 102 (2) ... 1 02 (m) request that the NGN of the network gateway component 106 located on the network 1 〇4. The network gateway component 106 routes these requirements to the host 108(1), 108(2).....108(n). Each host 108(1), 1〇8(2>···1〇8(η) is associated with a respective host identifier 214(1), 214(2)...214(n). Host identifier 2 1 4 may, for example, uniquely identify the end of an application from a set of endpoints, a particular type of conversational connection potentially pointing to the endpoint set. In a described implementation, the network gateway component 1 0 6 Related to network load balancing. With network load balancing (or other network gateways with path selection functionality), one or more path selection policies 508 may be used.

13373⁄43⁄43⁄4. 05 » * 选择 Path Selection Policy 508 may include those path selection policies. For example, a manager can write or set those path selection methods to cause a network load balancer to enter incoming packets and/or require a specified mode. Its delivery route. The path selection policy 508 may also include more flexible and/or extended path selection policies, extended path selection policies based on immediate parameters, such as health and load information for the host 108.

A network load balancing implementation for the network gateway component 106 may be implemented with full network load balancing functionality. This is a description of the continuation message 206(A) on the client's chat connection and the path selection operation 2 1 6(C). It is also possible to implement a network load balancing implementation for the network gateway component 106 with the functionality of separate network load balancing. This is a description of the continuation of the client's chat connection. 206(B) and path selection operation 512 °

In this exemplary network load balancing implemented with separate functional balances, the network gateway component 106 includes a transmitter 502, a classifier 504, and a host identifier (HI)-pair-network. A link table 506 of addresses (ΝΑ). Transmitter 502 forwards the packet between client 102 and host 108 using network 104 and internal network 110, respectively. The classifier 504 classifies packets, requests, connections, etc. to perform the path selection operation in order to implement the preservation functionality of the network load balancing functionality and/or the close relationship of the chat connections. Transmitter 502 and classifier 504 may be resident and executed on different devices of network gateway 106 or on a single device. Additionally, each transmitter 502 and classifier 504 may be distributed over a device. Moreover, perhaps 31 has a plurality of elements of the transmitter 5〇2 and/or elements of the classifier 504 in a network gateway 106. As illustrated, each classifier 5〇4 includes a host identifier-to-network address connection table 5〇6. Alternatively, a network gateway 106 may have only one host identifier for the connection list of network addresses 5〇6. The host identifier, the pair of network addresses, and the connection table 5 〇 6 may also be located and/or associated with different functional elements.

In a complete network load balancing operation, the client 102(1) sends a continuation message 2〇6(A) of the client chat connection to the network gateway element 106 on the network 104. The address ^^^ client 1〇2(1) has a previously established-talking connection at host 1〇8(1) and retains a conversation connection identifier assigned to a previously established conversation connection. 2 丨〇 (丨). The chat connection identifier 210(1) includes a host identifier 214(1) associated with the host 1〇8(1) » the client talk link's performance message 2〇6(A) including the chat connection identifier 2 I 0 (1).

In one implementation of the full network load balancing functionality, the network gateway component 106 is a continuation message for the client's chat connection. 2〇6(A) performs the path selection operation 2 1 6 (C). Since the continuation message 206(A) of the client chat connection has a talk line identifier 2 1 0( 1 ) containing a host identifier 2 1 4(1), the network gateway component 106 uses the chat connection. This host identifier 2 1 4 (1) portion of the identifier 2 1 0 ( 1 ) specifies the transmission path for the continuation message 206 (A) of the client chat connection. In general, the network gateway component 1〇6 uses the host identifier 214(1) as retrieved from the chat connection identifier 210(1) to talk to the client for the continuation message 206(A) to the host. 108 (]) specifies the transmission path" 32 page change special communication line $ & machine ignited # & machine identification 'this is, for the specified transmission path to the host 丨 08 (1) client continuation message 206 (A In the case of 'network gateway component 106', it may be inserted in the field of a destination address of the packet.

Or 214(1) Street, the network gateway component 106 may also perform a mapping of one of the host identifiers, the network address Η1. For example, it might be such a pair

& Execute - a computational operation or a query operation. For a computational operation, the host identifier 2 1 4 (1) is mapped to the network address via a formula, algorithm, etc., for a query operation, the host identifier 2 1 4 (1) is a diagram for accessing a host identifier-to-network address, the chart including a login to the host identifier 2 1 4 (1) to the network address Η 1, such as a host identifier - Pair-network address link table 506. Referring to Figure 6, an example of such a chart is further described below.

In a separate network load balancing operation, client 102(2) sends a continuation message 206(B) of the client talk connection to the address of network gateway component 106 on network 104. NGN. Client 1〇2(2) has a previously established talk connection at host 108(2) and retains a talk line identifier 210(2) assigned to the previously established talk line. This conversation connection identifier 210(2) includes the host identifier 2] 4(2) associated with the host 1〇8(2). The continuation message 206(B) of the customer's knowledge of the connection to the connection is the conversation connection identifier 2 1 0(2). In one of the implementations of the respective network load balancing functionality, the forwarder 502 receives the continuation message 206(B) of the client's chat connection. Because the client 33 13 two: year ^

The continuation message 206(B) of the conversation connection is an unknown connection (and possibly a new connection) to the transmitter 5〇2, and the continuation of the client conversation connection in the transmission 5〇2 in the pass 5 10 Message 2〇6(B) is forwarded to 5〇4. The continuation message 206(B) of the client chat connection has a talker identifier 21(2) of the charter identifier 214(2), so 504 uses a chat link to identify more in the path selection operation 512. This host identifier 214 (2) is divided into sections 206 (B) of the client chat connection. Also in the communication exchange 51, the classification returns a continuation message of the client's conversation connection 2〇6(B) to and/or adds a path selection login at 502 to indicate that the conversational continuation/packet is to be forwarded to the conversation. Host 1 〇 8 (2 ;). Therefore, the classifier 504 and the forwarder 5〇2 use the host identifier 214(2) as retrieved from the talker 210(2) to jointly connect the continuation message 206(B) to the host 108 ( 2) Specifying the transmission path In the above description of the path selection operation 216(c), the transmitter classifier 5 0 4 (1) may insert the host identifier 2丨4 (2) into the address of the address, (11) It is possible to execute the host identifier 2 1 4 (2) to map one of the nets H2 (eg 'one calculation, one query, etc.). The host identifier-pair-network address link table 5 〇 6 is described as part of the classifier 504. Although the host identifier-to-network address table 506 is shown as being located at the network gateway component 1 〇 6, it can reside in a different device (e.g., a proxy host device). One of the proxy devices in place is 'having a separate or integrated (eg, phase-load-balance) functionality. The network gateway component 丨〇6 can include a primary classifier from its conversational communication classifier. ^ 210(2) Transit 5 04 Transmitter line communication line to identify the intersection of the terminal.

The sixth and sixth diagrams are exemplary table 506 (A) and table 506 (B), respectively, which illustrate that the host identifier 214 and the network address 310 contain hints of path selection as a link. Host ID - Pair - Network Address Link Table 506 (A) generally corresponds to the implementation of the device mapped by host identifier 214. The host identifier-to-network address connection table 5 0 6 (Β) generally corresponds to the implementation of the application endpoint mapped by the host identifier 2 1 4 . However, referring to Fig. 3, as described above, the host identifier-to-network address join table 506(A) may also be mapped to the implementation of the application endpoint. As illustrated, the host identifier-to-network address connection table 5 06(A) links the respective host identifiers 214 to their respective network addresses 310. Table 506 (A) includes a plurality of registrations 602 (1Α), 602 (2Α)·.· 602 (ηΑ), each of the respective registrations 602 (1Α), 602 (2Α), 602 (ηΑ) including a respective Host identifiers 214(1), 214(2)...214(n) and a network address 310(1), 3 10(2)...31 0(n) each coupled thereto.

On the other hand, if in the same application Type application 36 program application sharing application identifier 3 Ο 8, then z can be less than w ifcb 〇 Figure 7 is a flow chart 700, which is described as using path selection An exemplary method illustrated in flowchart 700 includes eight blocks 702-716. While it is possible in other environments and with various hardware architectures and software plans to perform the actions of flowchart 700, in particular, some aspects and examples of this method are illustrated using Figures 1-3 and 5-6. For example, one or more of the network gateway elements 106 may perform the actions described herein.

In block 702, a client message is received. For example, network gateway component 106 may receive a client message from client 102 via network 104. In block 704, the contents of the received client message are checked. For example, network gateway component 106 may check one or more fields of a talkwire message 300, such as a field for a talkwire identifier 2 1 0.

In block 706, a determination is made as to whether the received client message is related to the chat connection. For example, if the received client message includes a chat connection message 3 0 2 having a field for a chat connection identifier 2 1 0, then the received client message chat connection is related to Conversation connection. On the other hand, if the received client message does not have a field for a chat connection identifier 2 1 0, then the received client message is not related to the chat connection and is in block 708. This method continues. In block 708, the received client message uses a predetermined policy to specify the transmission path. For example, the network gateway component 1 〇 6 may use the generic path selection policy of the path selection policy 508, such as a predetermined network-load-balance policy, to specify its transmission path for the received client message. 37 D 3pm 丄—os—___ Year Month Day (More) Page Change As indicated by the dashed arrow symbol 7 1 8 A, the network gateway component 1 0 6 may wait for the next client message reception. Alternatively, (in block 706) a determination is made as to whether the received client talk connection message is related to the chat connection, and a field of the talk link identifier is checked in block 71. For example, the network gateway component 106 may check the field of the conversation connection identifier of one of the received client chat connection messages 032. In block 712, a determination is made as to whether the client specifies a talkwire identifier for a field that uses the talkwire identifier. For example, the network gateway component 106 may determine whether a conversation connection identifier 2 1 0 is in the field of a conversation connection identifier of the conversation connection message 3 0 2 . If it is determined (at block 7 1 2) that no talk connection identifier is specified, then a default policy in block 708 may be used to specify the client chat connection start message 02 of the received client. Its transmission path. On the other hand, if it is determined (at block 7 1 2) that a chat connection identifier is specified by the client, then a host identifier in block 714 is retrieved from the specified talk link identifier. For example, network gateway component 106 may retrieve a host identifier 2 1 4 from a talkwire identifier 2 1 0 as specified in the continuation message 206 of the received client talk connection. In block 716, the host identifier retrieved is used to specify the transfer path for the received client message. For example, the continuation message 206 of the received client's talk connection may be routed to the host by the gateway element 106. The host 1 0 8 is associated with the host identifier 2 1 4 . This path selection may require a unpacked one of the host identifiers 214 to be inserted into a destination bar for a packet or packets forwarded to the host 108 38 Ι 33-782δι. t>5 -1- il ί ]

The bit, or this path selection, may require a pair of host identifiers 2 1 4 to at least one network address 310. It is possible to query the network address 3 1 0 using the host identifier 2 1 4 in a table 506, by performing a calculation on the host identifier 2 1 4 (eg, according to a formula, a real algorithm, etc.) It generates a network address 3 1 0, etc. to implement this mapping.

In particular, with respect to the implementation of the network gateway component 106 as a network load balancer, the network gateway component 106 may have robust and/or access to load information for a plurality of hosts 108. This robust and/or loaded information may indicate that a purpose associated with a retrieved host identifier 2 1 4 (eg, such a host 108 and/or an application terminal) is inappropriate or cannot handle a conversation. The continuation of the line, for reasons of soundness and / or load. In such a case, even when a client 102 has specified a talk line identifier 2 1 0 including a host identifier 2 1 4, the network gateway component 1 0 6 may select a policy for the preset path. Execute the action of block 7 0 8.

After the action of block 716, as indicated by the dashed arrow symbol 718, network gateway component 1 〇 6 may wait for the next client message reception. The network gateway component 106 may use the host identifier 2 1 4 retrieved in many methods depending on the type of host identifier 2 1 4 retrieved, and the continuation of the received client chat connection The message specifies its delivery path. For example, if a host identifier 2 1 4 includes a device identifier 3 0 6 and an application identifier 308, or if a host 3 1 2 (B) is mapped to a device and application for a host 108 Then, the network gateway component 106 may directly specify the transmission path to the intended application for the continuation message of the received client chat connection. In addition, the network gateway component 1063 may be able to use a network identifier 310 of a device identifier 3 4 6 of a host identifier 2 1 4 to implement the continuation of the received client's conversation connection. Message 2 0 6 specifies the host to which the transmission path is to the same relationship. 1 0 8 'The network address 310 is used as the destination address for the packet or packets of the specified transmission path. Alternatively, the network gateway component 106 may use one of the device identifiers 3 4 6 of the device identifier 3 4 6 to implement a key 312 (A) for querying the device of the cohort of the host 1 0 8 Network address 3 1 〇 ° For example '~Key 3 1 2(#) may be used to access a table 506 (A) (eg, a data structure) that will key 3 1 2 (A) The network address 310 is mapped to the host 1-8. A login 602 (#Α) with key 3 12(#) is located in this data structure. In the login 602 (#Α) in which it is located, a network address 3 10(#) linked to the key 312(#) is retrieved 'and used as a continuation of the client's conversation connection' message 2 06 Specify the transfer path to the host 1 of the family relationship 〇8. In addition, the network gateway component 106 may use a special key 3 1 2 (Β) implementation of an application endpoint of a device identifier 306 and an application identifier 3 1 of the host identifier 2 1 4 8 Querying a network address 3 1 0 with the host 1800 device and application identifier 308 for the genre relationship. For example, a key 312 (#) may be used to access a table 506 (B) (e.g., a data structure) that maps the key 3 1 2 (B) to the application endpoint of the host 108. A login 602 (#Β) with key 312(#) is located in this data structure. In the login 602 (#Β) where it is located, connect to the application endpoint of the secret record 3 12 (#) (for example, a network address 3 1 0 (#) and an application identifier 308 (#) The continuation message 206 that is retrieved and used to host/connect to the client's peer-to-peer relationship, to the continuation message 206 of the client-side conversational connection to the particular application, specifies its delivery path.
