Embodiment Construction

[0066] Hereinafter, some terms used in this application are explained to facilitate the understanding of those skilled in the art.

[0067] 1) Multi-homing networking, which is an emergency disaster recovery mechanism that can provide normal communication in the event of a sudden disaster in time. The multi-homing function means that one CE can belong to multiple different PEs at the same time. When one of the PEs fails, the services of the CE can be forwarded through other PEs.

[0068] 2) A unit in this application refers to a functional unit or a logic unit. It may be in the form of software, and its functions are realized through the processor executing program codes; it may also be in the form of hardware.

[0069] 3) "Multiple" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists ...

Abstract

The present application provides a message synchronization method and device, the method comprising: the first service provider edge router PE receives the first message sent by the customer edge equipment CE; the first PE adds the Ethernet The network segment identifier ESI obtains the second message; the ESI is the ESI corresponding to the access port of the first PE; The virtual link tunnel corresponding to the ESI; the first PE sends the second message to the second PE through the virtual link tunnel, and the second message is used to instruct the second PE to send the The CE sends a data packet, and both the first PE and the second PE are connected to the CE. The message synchronization method provided by this application can ensure the correct forwarding of data messages, thereby ensuring the normal operation of services in the network.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message synchronization method and device. Background technique [0002] With the development of communication technology, users have higher and higher requirements for the reliability of data transmission in the network. For the faults that occur during the transmission process, there are many protection methods in the existing technology, among which the dual-homing technology is very important. a method. [0003] figure 1 It is a schematic diagram of CE dual-homing networking in the prior art, such as figure 1 As shown, in this networking, customer edge device 1 (customer edge device, CE) is connected to service provider edge router 1 (provider edge device, PE) through port (PORT) 1, and connected to PE2 through port (PORT) 2. Both PE1 and PE2 are connected to PE3 through a network (such as a WAN), and PE3 is connected to CE2. In this way, there will ...
