Description

Method, equipment and system for distributing local media access control address

Technical Field

The present invention relates to network communication technologies, and in particular, to a method, a device, and a system for allocating a local Media Access Control (MAC) address.

Background

The expansion of the scale of the data center and the introduction of virtualization bring about not only the increase of physical devices but also the exponential growth of virtual devices. The proliferation of these devices has resulted in a dramatic rise in the consumption of MAC addresses. Whereas the conventional MAC address is a MAC address of 48 bits that the above-mentioned devices have been assigned to at the time of manufacture or shipment to facilitate communication between the devices.

The conventional MAC address has many problems in specific applications, such as: the capacity of the MAC address space cannot meet the increasingly consumed MAC addresses; the MAC address is fixed; the MAC addresses are not hierarchical and cannot provide other device-related information, such as location information. To solve the problems of the conventional MAC address, the Institute of Electrical and Electronics Engineers (IEEE) has proposed a concept of a local MAC address, i.e., a MAC address is no longer a globally unique 48-bit address in some network environments, but is a localized address unique within a network. And a unified address allocation mode can be adopted to uniformly allocate the local MAC address to each network element in the network.

Currently, for the allocation of the local MAC address, the local MAC address is usually applied in a form of sending a request data packet, so that the address allocation of the network device to the host and other devices is only involved, and the method is suitable for a small network, such as a vehicle-mounted internal small network scenario. For a large network, how to obtain the MAC address in multiple network devices needs a relevant protocol to complete. In addition, for the local MAC address allocation scheme, the host may implement MAC address acquisition in a self-declared manner, but the entire network architecture is a Client and Server (C/S) architecture, so that a centralized Server manner is adopted, and local MAC address allocation cannot be performed under other network architectures.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example one

Referring to fig. 1, it shows a flow of a method for allocating a local MAC address according to an embodiment of the present invention, where the flow is suitable for a device to be allocated in a network, where the local MAC address needs to be allocated, and the flow may include:

s101: the equipment to be allocated sends a registration message of a local MAC address;

specifically, in the embodiment of the present invention, the device to be allocated may implement obtaining the local MAC address in a self-declaration manner to the entire network, and therefore, the registration message may be sent to all device nodes in the entire network, or may be sent to the database server in a unicast manner. The database server holds the assigned and in-use MAC addresses, and can be used to centrally manage the overall network of MAC address assignments. The registration message may include: a message identifier for uniquely identifying the registration message and a MAC address block to be allocated to be registered. It is easily understood that the MAC address block to be allocated may contain one MAC address or a plurality of MAC addresses.

It can be understood that the MAC address block to be allocated, which needs to be registered in the registration message, may be obtained after the device to be allocated selects according to a preset selection policy. And the preset selection policy may preferably include: the device to be allocated learns the MAC address block that has not been used from the history of the data transmission over the entire network.

S102: when the device to be allocated does not sense any conflict, determining the MAC address block to be allocated as the MAC address of the device to be allocated, and sending a declaration message of the MAC address;

it should be noted that, the device to be allocated does not sense any conflict, and in particular implementation, it may preferably include:

when the device to be allocated transmits the registration message according to a preset interval period for a preset number of times, and does not receive a conflict failure message aiming at the registration message or a declaration message verified as an address conflict, determining that the device to be allocated does not sense the MAC address conflict to be applied;

wherein the collision failure message comprises: a message identifier for uniquely identifying the collision failure message and a MAC address block where a collision occurs; therefore, when the device to be allocated reselects the MAC address block to be allocated, the MAC address block with conflict included in the conflict failure message is avoided, and the retransmitted registration message has higher probability to avoid receiving the conflict failure message. In addition, the message identifier in the collision failure message and the message identifier in the registration message have a corresponding relationship, so that the registration message to which the collision failure message is directed can be known.

Specifically, the declaration message includes a message identifier for uniquely identifying the declaration message and a MAC address to be declared. It should be noted that, after receiving the declaration message, the network device in the network may establish and retain a forwarding mapping relationship between the receiving port that receives the declaration message and the MAC address that needs to be declared in the declaration message, and a specific retention form may be to update an existing forwarding table of the network device according to the established forwarding mapping relationship, so that when a subsequent network device needs to forward a message to the MAC address that needs to be declared, the message that needs to be forwarded is forwarded from the receiving port by querying the forwarding table, and thus broadcast transmission is not required.

For example, when the device to be allocated senses a conflict, the above scheme may further include:

the equipment to be allocated reselects the MAC address block to be allocated and retransmits the registration message;

it should be noted that the retransmitted registration message may include a message identifier for uniquely identifying the registration message and a reselected MAC address block to be allocated.

It will be appreciated that, based on the preceding description that no conflict is perceived by the device to be allocated, it can be seen that: when the device to be allocated receives a conflict failure message for the registration message or a declaration message that the registration message is verified to be an address conflict, the device to be allocated may determine that a conflict is perceived; the collision failure message may include a message identification for uniquely identifying the collision failure message and a MAC address block where the collision occurred,

illustratively, when the device to be allocated sends the registration message, then the process may further include: when the device to be allocated receives declaration information sent by other devices, the MAC address needing declaration in the declaration information sent by other devices and the MAC address block to be allocated which needs to be registered in the registration information are subjected to conflict detection, and whether conflict occurs is determined:

if the conflict occurs, reselecting the MAC address block to be allocated, and replacing the original MAC address block to be allocated, which needs to be registered, in the registration message with the reselected Mac address block to be allocated;

if no conflict occurs, the registration message is not processed; preferably, the registration message may also be continuously transmitted.

It can be understood that, the specific collision detection method may be to determine whether an intersection between the MAC address to be declared in the declaration message sent by the other device and the MAC address block to be allocated that needs to be registered in the registration message is empty, and if the intersection is empty, it indicates that a collision occurs; otherwise, no conflict is indicated.

The embodiment provides a local MAC address allocation method applied to equipment to be allocated, which is characterized in that the equipment to be allocated sends an MAC address block to be allocated to network equipment of the whole network, and the MAC address used by the equipment to be allocated is declared according to feedback of other network equipment of the whole network aiming at the MAC address block to be allocated, so that registration of the local MAC address and conflict detection of the local MAC address are realized, a local MAC address allocation protocol is realized in a plurality of network equipment, and the method can be suitable for different local network architectures.

Example two

Based on the same technical concept as the foregoing embodiment, referring to fig. 2, a flow of a method for allocating a local MAC address according to an embodiment of the present invention is shown, where the method may be applied to an allocated device to which a local MAC address is allocated in a network, and the flow may include:

s201: the distributed equipment receives a registration message sent by the equipment to be distributed;

specifically, the registration message may be sent to the whole network by a device to be allocated, which needs to allocate a local MAC address in the network, and the registration message may include: and the message identifier is used for uniquely identifying the registration message and the MAC address block to be allocated, which needs to be registered by the equipment to be allocated.

S202: the distributed equipment carries out conflict detection on the MAC address block to be distributed in the registration message and the local MAC address of the distributed equipment;

it should be noted that, since the native MAC address is a unique MAC address in the entire network, the devices in the network have only one corresponding native MAC address in the entire network. When the MAC address to be allocated in the registration message is not used by all allocated devices in the network, the device to be allocated can use the MAC address to be allocated in the registration message; when the MAC address to be allocated in the registration message is already used by the allocated device in the network, it indicates that the MAC address to be allocated in the registration message conflicts with the used MAC address, so that the device to be allocated cannot use the MAC address to be allocated in the registration message, and the MAC address to be allocated needs to be reselected. Therefore, collision detection by the allocated device has two results:

s203: when a conflict occurs, the distributed equipment sends a conflict failure message to the equipment to be distributed;

it should be noted that the collision failure message may include a message identifier for uniquely identifying the collision failure message and a MAC address block where the collision occurs.

It can be understood that the message identifier in the collision failure message may have a corresponding relationship with the message identifier in the registration message, so that the registration message to which the collision failure message is directed can be known.

Illustratively, when no conflict occurs, the technical solution of the present process may further include: the assigned device terminates the registration message.

It can be understood that after the allocated device terminates the registration message, the device to be allocated continues to send the declaration message when the collision failure message for the registration message is not received, so that the device to be allocated takes the MAC address to be declared in the declaration message as the local MAC address of the device to be allocated.

The embodiment provides a local MAC address allocation method applied to allocated equipment, which includes the steps that the allocated equipment receives an MAC address block to be allocated sent by the allocated equipment, collision detection is carried out according to the MAC address of the allocated equipment and the MAC address block to be allocated, a collision failure message is fed back to the allocated equipment when collision occurs, registration of the allocated equipment is terminated when no collision occurs, registration of local MAC addresses and collision detection of local MAC addresses are achieved, a local MAC address allocation protocol is achieved in a plurality of network equipment, and the local MAC address allocation method can be suitable for different local network architectures.

EXAMPLE III

Based on the same technical concept as the foregoing embodiment, referring to fig. 3, it shows a flow of a method for allocating a local MAC address according to an embodiment of the present invention, where the method may be applied to a network device for forwarding in a network, and the flow may include:

s301: the network equipment receives a registration message sent by the equipment to be distributed;

it should be noted that the registration message may include: a message identifier for uniquely identifying the registration message and a MAC address block to be allocated to be registered.

S302: the network equipment determines whether to forward the registration message to other network equipment except the equipment to be distributed in the network according to a preset forwarding strategy;

s303: when the network equipment receives the conflict failure message aiming at the registration message, the conflict failure message is forwarded to the equipment to be distributed.

It should be noted that the collision failure message may include a message identifier for uniquely identifying the collision failure message and a MAC address block where a collision occurs; the message identity of the collision failure message may typically be set to coincide with the message identity in the registration message. Therefore, the network device can query the corresponding relationship established in step S301 according to the message identifier in the collision failure message, so that the forwarding message can send the collision failure message to the device to be allocated from the receiving port of the registration message.

S303: when the network equipment receives the declaration message, the forwarding mapping relation is established according to the declaration message.

It should be noted that the declaration message includes a message identifier for uniquely identifying the declaration message and a MAC address to be declared. Therefore, the network device can establish a forwarding mapping relationship between the receiving port receiving the declaration message and the MAC address to be declared in the declaration message, and store the mapping relationship, and the specific storage form may be a form of a forwarding table entry. It can be understood that the network device has usually established a forwarding table, and after a new forwarding table entry is established, the new forwarding table entry may be updated to an existing forwarding table, so that when a subsequent network device receives a message to be sent to an MAC address that needs to be declared, the forwarding table may be retrieved to query a corresponding sending port, the message is directly forwarded from the sending port, and broadcast sending of the message is reduced.

For the technical solution shown in fig. 3, optionally, for the network device that determines whether to forward the registration message to other network devices in the network except the device to be allocated according to a preset forwarding policy in step S302, the method may include:

when the network equipment is provided with an agent of the allocated equipment, the network equipment carries out conflict detection on an MAC address block to be allocated in the registration message and a local MAC address of the allocated equipment of the network equipment agent; and the number of the first and second groups,

when a conflict occurs, the network equipment sends a corresponding conflict failure message; and the number of the first and second groups,

when no conflict occurs, the network device forwards the registration message to other network devices except the device to be distributed in the network.

It is understood that after the network device sends the corresponding collision failure message, the collision failure message is finally received by the device to be allocated.

Specifically, for the above alternative, the network device forwarding the registration message to other network devices in the network except the device to be allocated may include:

after the network equipment acquires a receiving port for receiving the registration message, establishing a corresponding relation between a message identifier of the registration message and the receiving port; and the number of the first and second groups,

It can be understood that, when the network device agent has other allocated devices, the behavior of the allocated devices is executed first, that is, collision detection is performed on the MAC address block to be allocated in the registration message, and a process of specifically performing collision detection may be as described in step S202 in embodiment two, which is not described in detail in this embodiment. And after the network equipment sends the conflict failure message to the equipment to be distributed, the registration message is not forwarded any more. After receiving the declaration message, the network device with proxy capability still needs to establish a forwarding mapping relationship according to the declaration message, so as to retain the MAC address to be declared in the declaration message.

Example four

In a specific implementation process, a MAC address registration message sent by a device to be allocated may not be sent to an allocated device or a network device in a network, and when a database server for centrally managing MAC address allocation is provided in the network, referring to fig. 4, a method for allocating a local media access control MAC address may include:

s401: a database server receives a registration message sent by equipment to be distributed;

wherein the registration message comprises: the message identifier is used for uniquely identifying the registration message and the MAC address block to be allocated, which needs to be registered;

specifically, for step S401, when the device to be allocated sends the registration message to the database server, the registration message may be sent in a unicast manner, so that the database server can receive the registration message.

S402: the database server carries out conflict detection on the MAC address to be distributed and the stored MAC address:

wherein, the saved MAC address is the MAC address in the use state in the whole network;

s403: when a conflict occurs, the database server sends a conflict failure message to the equipment to be distributed;

wherein the collision failure message comprises a message identifier for uniquely identifying the collision failure message and a MAC address block where collision occurs.

It should be noted that when no conflict occurs, the database server does not respond to the registration message, which is terminated at the database server.

Illustratively, the method further comprises:

It can be understood that, after the database server stores and sets the MAC address to be declared in the declaration message to the use state, the database server updates the stored MAC address, so that collision detection can be performed subsequently through the updated stored MAC address.

EXAMPLE five

Based on the same technical concept of the foregoing embodiments, the present embodiment explains the technical solutions of the foregoing three embodiments by a specific example. The embodiment is implemented by extending the MRSP Protocol based on the MRP Protocol, and may be referred to as a Multiple MAC Assignment Protocol (MMAP); three types of messages may be included in the MMAP: MAC address registration messages, MAC address collision messages, and MAC address declaration messages. In addition, the three types of messages can be carried by an MMAP Data Unit (MMAPDU), and in the MMAPDU, three values are added to an AttributeType field to correspond to the three types of messages; the vectorattetbute byte in the AttributeList field can be defined as two kinds: the message identifies a messageID attribute and an MAC address attribute; the message ID attribute contains a message ID for distinguishing different messages. In this embodiment, 48-bit MAC address start value plus 16-bit random ID may be preferably used for representation; and the MAC address attribute comprises a MAC address starting value and the number of the MAC addresses.

The present embodiment is explained based on the networking structure shown in fig. 5, where in fig. 5, the device to be allocated is T; the allocated device is L; the network equipment for forwarding is B; it should be noted that when the Network device is provided with an agent, B may play a role of T or L, and the devices are connected through a Local Area Network (LAN), as shown by a circle in fig. 5.

When T needs to apply for a part of MAC address, a MAC address registration message is sent; the AttributeList carried in the registration message is shown in fig. 6, and includes a messageID attribute and a MAC address attribute; the MAC address attribute comprises an MAC address space to be allocated, which needs to be registered;

and B, after receiving the MAC address registration message, storing the corresponding relation between the messageID in the MAC address registration message and a receiving port for receiving the MAC address registration message, forwarding the MAC address registration message to other ports, and receiving the MAC address registration message sent by T by other L through the forwarding of B.

It can be understood that the above sending process for the MAC address registration message is shown in fig. 7, the direction of the arrow is the transmission direction of the MAC address registration message, R near the arrow represents the MAC address registration message, and S in the block of B represents that B stores the correspondence between the messageID in the MAC address registration message and the receiving port that receives the MAC address registration message.

After receiving the MAC address registration message, the L may check whether the MAC address to be allocated that needs to be registered conflicts with the MAC address of the present device: if not, terminating the MAC address registration message; if so, sending an MAC address conflict message; the AttributeList carried in the MAC address collision message also carries a messageID attribute and a MAC address attribute as shown in fig. 8, but the MAC address attribute at this time indicates a MAC address space with collision. Generally, the messageID attribute value in the MAC address collision message is the same as the messageID attribute value in the MAC address registration message, so that the registration message for which the collision failure message is intended can be characterized.

After receiving the MAC address collision message, B forwards the MAC address collision message to T according to the messageID in the MAC address collision message and the correspondence relationship stored in B shown in fig. 7.

It can be understood that the above-mentioned transmission process for the MAC address collision message is shown in fig. 9, the direction of an arrow is the transmission direction of the MAC address collision message, C near the arrow indicates the MAC address collision message, and P in the block of B indicates that the correspondence relationship stored in B is stored.

T can wait for the sending of MAC address registration message once in the preset interval period, after the MAC address registration message is sent for a plurality of times continuously, if no MAC address conflict message is received, the MAC address declaration message is sent to the whole network; if the MAC address conflict message is received in the period of time, a new MAC address to be allocated needs to be reselected and the MAC address registration message needs to be retransmitted, and at the moment, the message ID also changes along with the reselected MAC address.

After receiving the MAC address declaration message, the network device B may establish a forwarding mapping relationship between the declared MAC address and the receiving port according to the MAC address declared in the MAC address declaration message and the receiving port that received the declaration message, and update the forwarding mapping relationship to a forwarding table of the network device B itself. The specific preservation form can be as follows: the declared MAC address is saved to the destination address and the receive port is saved to the output port. Therefore, after a message of the MAC address to be declared is received subsequently, the forwarding table can be searched to find the output port, the message is directly forwarded to the T, and the message is reduced from being sent in a broadcasting mode.

It is to be understood that the above-mentioned transmission process for the MAC address declaration message is shown in fig. 10, the direction of the arrow is the transmission direction of the MAC address declaration message, and a near the arrow represents the MAC address declaration message.

EXAMPLE six

In addition to the fifth embodiment, in this embodiment, the explanation of the specific implementation procedure is performed by the agent whose B has L, and in the case of the agent whose B has L, since the MAC address of the proxied L is stored in B, the MAC address collision message can be replied instead of the proxied L. The specific implementation process of this embodiment is as follows:

after receiving the MAC address registration message, B may store a correspondence between the messageID in the MAC address registration message and the receiving port that receives the MAC address registration message, and for B that does not have an agent, may transmit the MAC address registration message according to the process shown in fig. 7, which is not described in detail in this embodiment.

For B provided with an agent, the behavior of L is performed first, namely:

b, detecting whether the MAC address stored by the B and the MAC address to be distributed which needs to be registered conflict or not by the B provided with the agent: if there is a collision, B will proxy L to send a MAC collision message. Otherwise, terminating the MAC address registration message and not forwarding.

It is to be understood that a schematic diagram of the B provided with the agent sending the MAC address collision message is shown in fig. 11, the B provided with the agent is shown as a hatched block with oblique lines, and the arrow direction is the transfer direction of the MAC address collision message sent by the B provided with the agent.

For the L that receives the MAC address registration message and the B that is not provided with the proxy, the specific implementation process of this embodiment is similar to that of the fourth embodiment, that is:

For B without agent, after receiving MAC address declaration message, according to MAC address declared in MAC address declaration message and receiving port receiving the declaration message, establishing forwarding mapping relation between declared MAC address and receiving port, and updating the forwarding mapping relation to self forwarding table of B. The specific preservation form can be as follows: the declared MAC address is saved to the destination address and the receive port is saved to the output port. Therefore, after a message of the MAC address to be declared is received subsequently, the forwarding table can be searched to find the output port, the message is directly forwarded to the T, and the message is reduced from being sent in a broadcasting mode.

For the B device provided with the agent L application, if the MAC address declaration message is received, the MAC address declared in the MAC address declaration message is stored.

For the L device, if the MAC address of the L device has not been declared, when the MAC address declaration message of another T is received, the declared MAC address in the MAC address declaration message is also stored, and is used as a basis for selecting the MAC address to be allocated that needs to be registered, so that collision repetition is avoided.

For other T, after the MAC address to be allocated which needs to be registered by the device is selected, when the MAC address registration message is sent, if the MAC address declaration message sent by other T is received, the conflict detection is carried out on the life MAC address in the MAC address declaration message sent by other T and the MAC address to be allocated which needs to be registered and is selected by the device; if there is a conflict, the MAC address to be allocated that needs to be registered needs to be reselected, and the process of sending the MAC address registration message begins again.

EXAMPLE seven

For some lightweight devices, the MRP Protocol may not be supported, and this embodiment is implemented in an Edge Control Protocol (ECP) Protocol based on a Link Layer Discovery Protocol (LLDP), and the specific implementation process is the same as that in the fourth embodiment and the fifth embodiment, and the content is different from that in the fifth embodiment and the sixth embodiment: the message content in the different messages is carried in the form of Type-Length-Value (TLV) in LLDP Data Unit (LLDPDU, LLDP Data Unit), as shown in fig. 12, the field TLVtype indicates the Type of TLV, for the embodiment, three TLV types are defined, namely TLV Type — Register, indicating that it is for MAC address registration message; TLV type ═ Conflict, which indicates that it is a MAC address collision message; TLV type ═ Announce, indicates that it is a MAC address declaration message. The field TLV Length is a Length indicating this TLV. The field TLVValue mainly includes two kinds of information: message ID and MAC start address; for the Message ID, the unique identity of the Message is indicated, and for the MAC start address, the start value of the MAC address block has different meanings in different Message types. If the message is in the registration message, the MAC address block which needs to be registered is indicated; if the MAC address block is in the conflict message, the MAC address block is used by other equipment, and a conflict exists, so that a new MAC address block needs to be reselected; if the message is a declaration message, the MAC address block is formally used by the device, and other devices cannot use the MAC address block. The number of fields indicates the number of addresses of the address block.

Example eight

The technical solutions of the fifth embodiment and the sixth embodiment may also be implemented based on a Gratuitous Address Resolution Protocol (Gratuitous ARP), and the specific implementation process is the same as that of the fourth embodiment and the fifth embodiment, except that the existing free ARP packet needs to be expanded. Therefore, the expanded free ARP message can bear the message content in different messages. The embodiment provides a preferred extension scheme, which is to extend the gratuitous ARP packet, but is not limited to the extension scheme. In a preferred extension scheme, for the MAC address registration message, the following attribute values in the gratuitous ARP message are set, specifically:

opcode 10, which indicates a type of MAC address registration message;

sender MAC: filling in the initial address of the MAC address block;

sender IP: if yes, filling, and if not, 0 is obtained;

destination MAC: filling the final address of the MAC address block;

destination IP: fills in the same address as Sender IP.

In a preferred extension scheme, for a MAC address collision message, the following attribute values in the gratuitous ARP message are set, specifically:

opcode is 11, and the type is MAC address conflict message;

sender MAC: filling the initial address of the conflict MAC address block;

sender IP: if yes, filling, and if not, 0 is obtained;

destination MAC: filling the final address of the conflict MAC address block;

destination IP: fills in the same address as Sender IP.

In a preferred extension scheme, for the MAC address declaration message, the following attribute values in the gratuitous ARP message are set, specifically:

opcode 12, indicating a type of MAC address declaration message;

sender MAC: filling in the initial address of the stated MAC address block;

sender IP: if yes, filling, and if not, 0 is obtained;

destination MAC: filling in the last address of the claimed MAC address block;

destination IP: fills in the same address as Sender IP.

The technical scheme has the advantages that the technical scheme can be combined with the IP address based on the free ARP, and the corresponding relation between the MAC address and the IP address can be directly established after a declaration message for the condition that the equipment T to be allocated already has the IP address.

It can be understood that the fifth to eighth embodiments only disclose implementation processes of the technical solutions of the first to third embodiments under different protocols, and are not specific limitations on the embodiments of the present invention.
