Multicast message processing method and switch chip in distributed link aggregation network

Abstract

The invention, which is applied to the technical field of network communication, discloses a multicast message processing method and switch chip in a distributed link aggregation network. The method comprises: a multicast message is copied to a switch chip of each switch with a multicast group member port; the switch chips copy the multicast message to the multicast group member ports in the switches; a port convergence group in the multicast group is configured to each switch with the multicast group member port, wherein the member port configuration sequences of the port convergence groups are kept to be consistent and selection strategies of the member ports in the port convergence groups are kept to be consistent; and whether the selected member ports in the port convergence groups are ones of the switch chips; if so, the multicast message is forwarded; and if not, the multicast message is abandoned. Therefore, effects of reducing the design cost of the switch chip and lowering the maintenance cost can be realized.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a multicast message processing method and a switching chip in a distributed link aggregation network. Background technique [0002] In a distributed system, ports on different switches need to be added to the same port aggregation group, and the packets sent to this port aggregation group should only be forwarded through a member port in this aggregation group. For unicast packets, There is only one destination port, so the unicast message sent to the port aggregation group only needs to select the only member port according to the rules of the port aggregation group to select the member port, and then the message can be forwarded. [0003] For multicast packets or broadcast packets, after the packets enter the distributed system, they may be copied to multiple exits of multiple switching chips. In order to ensure that only one packet in the link aggregation group i...

[0004] The current implementation method requires an additional storage device in the switch chip to save the configuration of the multicast isolation table, and software is required to maintain the multicast isolation table of each port aggregation group. When the port aggregation group has When the member port changes, the multicast isolation table corresponding to the port aggregation group needs to be adjusted, and the software maintenance cost is high
