Problems solved by technology

In addition, for the local MAC address allocation scheme, the host can obtain the MAC address through self-declaration, but the entire network architecture is a client and server (C / S, Client / Server) architecture, so a centralized server is adopted In other network architectures, the local MAC address cannot be assigned

Embodiment 1

[0127] see figure 1 , which shows a flow of a method for allocating a local MAC address provided by an embodiment of the present invention. The flow is applicable to a device to be assigned a local MAC address in the network, and the flow may include:

[0128] S101: The device to be allocated sends a registration message of the local MAC address;

[0129] Specifically, in the embodiment of the present invention, the device to be allocated can realize the acquisition of the local MAC address by self-declaring to the whole network. Therefore, the registration message can be sent to all device nodes in the whole network, or through unicast sent to the database server. The database server stores the allocated and in-use MAC addresses, and the database server can be used to centrally manage the allocation of MAC addresses in the entire network. The registration message may include: a message identifier for uniquely identifying the registration message and a MAC address block to b...

Embodiment 2

[0146] Based on the same technical idea of ​​the foregoing embodiments, see figure 2 , which shows a flow of a method for assigning a local MAC address provided by an embodiment of the present invention, the method may be applicable to allocated devices in the network that have been assigned a local MAC address, and the flow may include:

[0147] S201: The allocated device receives the registration message sent by the device to be allocated;

[0148] Specifically, the registration message may be sent to the entire network by a device to be assigned a local MAC address in the network, and the registration message may include: a message identifier used to uniquely identify the registration message and an ID for which the device to be assigned needs to register. MAC address block to be allocated.

[0149] S202: The allocated device performs conflict detection between the MAC address block to be allocated in the registration message and its own local MAC address;

[0150] It sh...

Embodiment 3

[0158] Based on the same technical idea of ​​the foregoing embodiments, see image 3 , which shows a flow of a method for assigning a local MAC address provided by an embodiment of the present invention, the method may be applicable to a network device performing forwarding in the network, and the flow may include:

[0159] S301: The network device receives the registration message sent by the device to be allocated;

[0160] 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 for registration.

[0161] S302: The network device determines whether to forward the registration message to other network devices in the network other than the device to be allocated according to a preset forwarding strategy;

[0162] S303: When the network device receives the conflict failure message for the registration message, forward the conflict failure message to the device t...

Abstract

The embodiment of the invention discloses a local media access control address allocation method and system and equipment. The method may comprise the steps that to-be-allocated equipment sends a registration message of a local MAC (Media Access Control) address; and when the to-be-allocated equipment does not sense any collision, a to-be-allocated MAC address block is determined as the MAC address of the to-be-allocated equipment, and a declaration message of the MAC address is sent.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a method, device and system for allocating local Media Access Control (MAC, Media Access Control) addresses. Background technique [0002] The expansion of data center scale and the introduction of virtualization not only bring about the increase of physical equipment, but also bring about the exponential growth of virtual equipment. The growth of these devices has led to a sharp increase in the consumption of MAC addresses. However, the current traditional MAC address is a fixed 48-bit MAC address assigned to the above-mentioned devices when they are manufactured or shipped out of the factory, so as to facilitate communication between devices. [0003] However, traditional MAC addresses will have many problems in specific applications, such as: the capacity of MAC address space can no longer meet the increasing consumption of MAC addresses; MAC addresses are fixed; MA...
