2. Video networking packet definition
2.1 Access network packet definition
The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.
As shown in the following table, the data packet of the access network mainly includes the following parts:
DA SA Reserved Payload CRC
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;
the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);
the reserved byte consists of 2 bytes;
the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;
the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
DA SA Reserved label (R) Payload CRC
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.

Referring to fig. 6, on the basis of the system shown in fig. 5, a flowchart of a first step of a videophone dialing method according to an embodiment of the present invention is shown, which may specifically include the following steps:
step S601: the streaming media server 502 receives a first videophone request sent by the mobile terminal 501; wherein, the first videophone request is generated by the mobile terminal 501 when receiving a trigger operation of dialing the target videophone network terminal 506;
in various embodiments of the present invention, the mobile terminal 501 may be an internet terminal, for example, a terminal device capable of playing audio and video, such as a smart Phone, a tablet, a Personal Digital Assistant (PDA), and the like, and an operating system of the terminal device may include Android (Android), IOS, Windows Phone, Windows, and the like, which is not limited in this embodiment of the present invention.
The internet of view terminal 506 is an internet of view service ground device, the actual participant or server of the internet of view service. The video network terminal 506 can be developed based on a Ti816x chip, is positioned as a development platform of a high-end video network terminal 506, can support various functions in the video network, supports full-high-definition audio and video coding and decoding by hardware, and has superior multi-channel coding and decoding capability and a stable system. The video networking terminal 506 may include various conference set-top boxes, video telephony set-top boxes, surgical trial set-top boxes, and the like.
The mobile terminal 501 has a plurality of display interfaces, such as a dial interface, an address book interface, and the like.
The triggering operation of dialing the target video network terminal 506 may be that a user using the mobile terminal 501 inputs a terminal number of the target video network terminal 506 on a dialing interface of the mobile terminal 501, and then clicks a call button; or a voice call button that a user using the mobile terminal 501 selects an image or number of the video network terminal 506 in the address book interface of the mobile terminal 501 and then clicks.
The mobile terminal 501 generates a first video phone request according to the triggering operation, where the generated first video phone request includes the terminal number of the target video network terminal 506 and the area code of the area where the target video network terminal 506 is located. Then, the mobile terminal 501 sends the first videophone request to the streaming server 502 through the internet.
Step S602: the streaming server 502 sends the first videophone request to the 16-bit videophone network server 503; the 16-bit video networking server 503 is configured to send the first video telephony request to the service bridging server 504; the service bridging server 504 is configured to convert the first videophone request based on the 16-bit video networking protocol into a second videophone request based on a 64-bit video networking protocol, and send the second videophone request to the 64-bit video networking server 505; the 64-bit video networking server 505 is configured to send the second video telephony request to the target video networking terminal 506; the target video networking terminal 506 is configured to return first audio and video data based on a 64-bit video networking protocol for the second video telephone request;
the video network server is a core server in the video network, and devices (such as the video network terminal 506 and the like) accessing the video network are registered in the video network server in advance to perform video network services. In various embodiments of the present invention, the video networking server comprises a 16-bit video networking server and a 64-bit video networking server, the 16-bit video networking server 503 can access the 16 th power video networking terminal 506 of 2, and the 64-bit video networking server 505 can access the 64 th power video networking terminal 506 of 2.
According to the access characteristics of the video network server, aiming at the technical problem of the present invention, in order to communicate with the video network terminal 506 under the 64-bit video network server 505, the mobile terminal 501 needs to communicate with the 64-bit video network server 505 first, but due to the difference between the 64-bit and 16-bit video network protocols, the mobile terminal 501 cannot perform video telephone service with the terminal under the 64-bit video network through the video network.
In the embodiment of the present invention, the 16-bit video network server 503 includes a plurality of 16-bit virtual terminal numbers;
the step of the streaming server 502 sending the first videophone request to the 16-bit videophone server 503 further comprises the following sub-steps:
substep 1: the streaming media server 502 generates a video networking access instruction according to the first video telephone request;
substep 2: the streaming media server 502 sends the video networking instruction to the 16-bit video networking server 503; the 16-bit internet-of-video server 503 is configured to determine, according to the internet-of-video instruction, a target 16-bit virtual terminal number in an idle state from the plurality of 16-bit virtual terminal numbers;
substep 3: the streaming media server 502 receives the target 16-bit virtual terminal number sent by the 16-bit video network server 503;
substep 4: the streaming media server 502 sends the first videophone request to the 16-bit video networking server 503 through the target 16-bit virtual terminal number.
In the embodiment of the present invention, the streaming media bridge server is not always connected to the video network server, and only when a video telephone request is sent to the streaming media server 502, the streaming media server 502 is triggered and then registers on the 16-bit video network server 503, so as to access the video network for video network service. After registration, the video server may allocate information such as a 16-bit virtual terminal number, a Media Access Control (MAC) address, and the like to the streaming server 502.
Therefore, in this embodiment of the present invention, after receiving the first videophone request, the streaming server 502 processes a protocol packet of the first videophone request, converts the first videophone request based on the internet protocol into the first videophone request based on the video networking protocol, and then sends the first videophone request to the 16-bit videophone networking server 503 through the target 16-bit virtual terminal number.
Further, the streaming server 502 converting the first internet protocol-based videophone request into the first video internet protocol-based videophone request may include the following steps:
first, the streaming media server 502 removes the internet packet header in the first video telephone request, and encapsulates the body of the first video telephone request and the video network packet header.
Second, the streaming server 502 encapsulates a video network header outside the first video phone request.
Next, the 16-bit video network server 503 sends the first video telephone request to the service bridging server 504.
The service bridging server 504 can make up the shortage that the video network server which is based on 16-bit development and has the length of 0xFFFF (65535 numbers) does not meet the use requirement of actual large data volume. The bridging server may use bridging software, and may implement operations such as data forwarding between different video network terminals 506. In the embodiment of the present invention, the service bridging server 504 communicates with the 16-bit video network server and the 64-bit video network server 505 respectively, and is used for bridging between the 16-bit video network server and the 64-bit video network server 505 with different protocols, so as to ensure cross-protocol forwarding of service data. For specific implementation, the service bridging server 504 includes two video networking ports, a 16-bit video networking port and a 64-bit video networking port, where the 16-bit video networking port is connected to the 16 video networking server through the first video networking switch; the 64-bit internet-of-view port is connected to a 64-bit internet-of-view server 505 through a second internet-of-view switch. The service bridging server 504 can upgrade the service data in the 16-bit network card of the video network and package the upgraded service data into service data which can be identified by the 64-bit network card of the video network and is based on the 64-bit protocol of the video network.
Therefore, after receiving the first videophone request sent by the 16-bit video networking server 503, the service bridging server 504 converts the first videophone request based on the 16-bit video networking protocol into a second videophone request based on the 64-bit video networking protocol, and then sends the second videophone request to the 64-bit video networking server 505. Specifically, the service bridging server 504 in the embodiment of the present invention converts the first videophone request into the second videophone request, which can be implemented by bridging the box number. Namely, the service bridging server 504 finds a 16-bit bridging box number to generate a binding relationship with a 16-bit video network server, finds a 64-bit bridging box number to generate a binding relationship with a 64-bit video network server, and then encapsulates the packet header of the first video telephone request into a second video telephone request based on a 64-bit video network protocol by referring to the method for converting the first video telephone request based on the internet protocol into the first video telephone request based on the video network protocol, and then uses the two bridging box numbers to realize data forwarding of the 16-bit and 64-bit protocols. The embodiment of the invention adopts the mode of forwarding the bridging box number, does not need to change the architecture of the original video networking server, does not need to transform the video networking system by a large amount of manpower and material resources, does not need to consume a large amount of resources to carry out data interaction between external equipment and the video networking system, improves the compatibility of the video networking system, and avoids unnecessary resource consumption.
Of course, in the internet of view, there are many service bridge servers 504, there may be one service bridge server 504 in the area where one 16-bit internet of view server 503 is located, and there may be one in many areas where 64-bit internet of view server 505 is in the development stage and may be less than 16-bit internet of view server 503. Therefore, the service bridging server 504 according to the embodiment of the present invention may also register in the 64-bit video network server 505, and after the service bridging server 504 sends the second video telephone request to the 64-bit video network server 505, the 64-bit video network server 505 may identify the service bridging server 504 and establish a long-time connection with the service bridging server 504, so that data may be quickly returned to the service bridging server 504 at a later stage.
Since the generated first videophone request includes the terminal number of the target video network terminal 506, after receiving the second videophone request, the 64-bit video network server 505 determines the MAC address registered by the target video network terminal 506 itself according to the terminal number, and then sends the second videophone request to the target video network terminal 506 according to the MAC address. If the target video network terminal 506 is not in an occupied state, for example, when the target video network terminal is not in a call with another person or in a conference, after receiving the second video network request, the target video network terminal 506 automatically returns the currently collected local audio and video (i.e., the first audio and video data in the embodiment of the present invention) to the 64-bit video network server 505.
Step S603: the streaming media server 502 receives second audio and video data sent by the 16-bit video network server 503; the second audio/video data is converted into a 16-bit video networking protocol by the service bridging server 504, and is sent to the 16-bit video networking server 503; the first audio/video data is sent to the 64-bit video network server 505 by the target video network terminal 506, and is sent to the service bridging server 504 by the 64-bit video network server 505;
step S604: the streaming media server 502 sends the second audio/video data to the mobile terminal 501; the mobile terminal 501 is configured to decode the second audio/video data.
In step S603, the method for the 64-bit video network server 505 to convert the first audio/video data sent by the target video network terminal 506 into the second audio/video data through the service bridging server 504, and then return the second audio/video data to the streaming media server 502 is a reverse process of step S602, and the principle is the same, which is not described herein again. Then, after receiving the second audio/video data based on the video networking protocol sent by the 16-bit video networking server 503, the streaming media server 502 converts the second audio/video data based on the video networking protocol into the second audio/video data based on the internet protocol, and then sends the second audio/video data based on the internet protocol to the mobile terminal 501, the mobile terminal 501 decodes and plays the second audio/video data, and simultaneously sends the currently acquired local audio/video data to the target video networking terminal 506 through the methods provided in steps S601 to S602, so that the way that the mobile terminal 501 performs the video telephone service with the terminal under the 64-bit video networking through the video networking is realized, and the service range of the video networking is widened.
The scheme provided in the first embodiment is directed to a scenario in which the streaming media server 502, the 16-bit video networking server 503, the service bridging server 504, and the 64-bit video networking server 505 are all located in the same area, so that the streaming media server 502 can determine the bridging number of the service bridging server 504 according to the area code where the 16-bit video networking server 503 is located, and is in communication connection with the service bridging server 504 through the bridging number, thereby further completing the scheme of performing video telephone communication with the video networking terminal 506 under the 64-bit video networking server 505.
In practical applications, the 64-bit video network server 505 and the service bridging server 504 connected to the 64-bit video network server 505 are usually not located in the same area as the 16-bit video network server 503, and at this time, the streaming media server 502 does not know the bridging number of the service bridging server 504, so how to implement the communication with the service bridging server 504 connected to the 64-bit video network server 505 is provided in the embodiments of the present invention as follows:
referring to fig. 7, a schematic structural diagram of a cross-region videophone dialing system according to an embodiment of the present invention is shown, in the system, there are a plurality of service bridge servers 504, each region where the 64-bit video network server 505 is located is provided with one service bridge server 504, and the service bridge server 504 has a unique bridge number; the video network further comprises a built-in bridge server 701, and the built-in bridge server 701 is respectively in communication connection with the 16-bit video network server 503 and the plurality of service bridge servers 504;
the first videophone request comprises an area code of an area where the target 64-bit videophone server 505 is located;
based on the system of fig. 7, referring to fig. 8, a flowchart of steps of a method for dialing a cross-regional videophone according to an embodiment of the present invention is shown, where the method further includes the following steps:
step S801: the streaming media server 502 sends the area code to the 16-bit internet of view server 503; the 16-bit internet of view server 503 is configured to send the area code to the built-in bridge server 701; the built-in bridge server 701 is configured to determine a bridge number of the target service bridge server 504 according to the area code, and send the bridge number to the 16-bit video network server 503;
step S802: the streaming media server 502 receives the bridge number sent by the 16-bit video network server 503;
in the embodiment of the present invention, a default bridge number is embedded in the streaming media server 502, and the default bridge number is a bridge number of the built-in bridge server 701, and the streaming media server 502 can communicate with the built-in bridge server 701 through the default bridge number. The built-in bridge server 701 stores bridge numbers of a plurality of service bridge servers 504, and since one service bridge server 504 is arranged in the area where each 64-bit video network server 505 is located, after the streaming media server 502 sends the area code of the area where the target 64-bit video network server 505 is located to the built-in bridge server 701 through the 16-bit video network server 503, the built-in bridge server 701 can find the bridge number of the target service bridge server 504 corresponding to the area code through the area code, and then returns the bridge number to the streaming media server 502 through the 16-bit video network server 503.
The streaming server 502 sends the first videophone request to the 16-bit videophone network server 503; the step that the 16-bit video networking server 503 is configured to send the first video telephony request to the service bridging server 504 further includes:
step S803: the streaming media server 502 adds the bridge number to the first videophone request, and sends the first videophone request added with the bridge number to the 16-bit video networking server 503; the 16-bit video networking server 503 is configured to send the first video telephony request to the target service bridging server 504 corresponding to the bridging number.
Next, after the streaming media server 502 adds the bridge number to the first videophone request, the 16-bit video networking server 503 may analyze the first videophone request to obtain the bridge number, and then the first videophone request is sent to the target service bridge server 504 corresponding to the bridge number. Next, the target service bridging server 504 completes the operation as described in step S602, and the built-in bridging server 701 is not used in the subsequent operation.
In the following, a specific example is adopted to further explain the cross-area videophone dialing method, in this example:
the a user dials the 0991-210050 telephone number using a mobile phone (the mobile terminal 501 according to the embodiment of the present invention) and requests communication with the B user (the video network terminal 506 according to the 64-bit video network protocol according to the embodiment of the present invention) using a 64-bit terminal with a terminal number of 210050. The mobile phone transmits 0991-. The streaming media server 502 adds 42276 to the first videophone request which is sent out 0991-210050, then sends the first videophone request added with 42276 to the 16-bit video networking server 503, and the 16-bit video networking server 503 sends the first videophone request to the Sinkiang bridge server according to 42276. The Sinkiang bridge server converts the first video telephone request into a second video telephone request based on a 64-bit video networking protocol, sends the second video telephone request to the 64-bit video networking server 505, the 64-bit video networking server 505 determines an MAC address corresponding to 210050 according to the terminal number of 210050, and then sends the second video telephone request to a video networking terminal 506 corresponding to the MAC address.
Next, when the video network terminal 506 used by the user B is not in an occupied state, the currently acquired first audio/video data is sent to the 64-bit video network server 505, the 64-bit video network server 505 sends the first audio/video data to the Xinjiang bridge server, the Xinjiang bridge server converts the first audio/video data into second audio/video data based on a 16-bit video network protocol, then the second audio/video data is sent to the streaming media server 502 through the 16-bit video network server 503, and the streaming media server 502 sends the second audio/video data to the mobile phone, so that the user a and the user B can communicate through the video phone.
In summary, the embodiment of the present invention can solve the problem that the built-in bridge server 701 is used to communicate with the service bridge server 504 across areas in two independent video networking environments, and the bridge number of the service bridge server 504 does not need to be input during dialing, thereby shortening the length of the number input by the user and simplifying the operation of the user. The built-in bridge server 701 and the service bridge server 504 of the embodiment of the invention use the video networking protocol in each node communication, and the security of the video networking protocol structure ensures that the network is not attacked.
