Abstract

The embodiment of the invention provides synchronization method and device for MAC (Media Access Control) address table information of a distributed network processing system. In the method, during the transmission of a service message of the same service, a service processing board receiving the service message learns or updates the MAC address table information corresponding to the MAC address according to the MAC address of the service message, the MAC address table information is the corresponding relationship between the MAC address and the port of the service processing board; at the same user network interface side or the same network interface side of the distributed network processing system, the MAC address table information is synchronized to another service processing board of the distributed network processing system if the transmission port receiving the service message and the transmission port transmitting the service message are not located on the same service processing board. The efficiency for the synchronization of the MAC address table information is improved, and the space occupied by the MAC address table information is saved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for synchronizing MAC (Media Access Control, Media Access Control) address entry information of a distributed network processing system. Background technique [0002] A distributed network processing system, such as a distributed network bridge, is used to connect isolated local area networks into a local area network, and to transmit service packets between each area network. The transmission of the service message needs to be realized according to the MAC address of the service message and the MAC address entry information of the service processing board. The MAC address of the service message includes the source address and the destination address, and the MAC address entry information records the correspondence between the MAC address and the port of the service processing board. [0003] When the service message is transmitted, according t...
