Problems solved by technology

Even if all users on a node leave, because the ring network port is still in the multicast group, according to the mechanism of the last user leaving in Proxy mode, no leave message will be sent to the source port at this time, so the multicast cannot be interrupted on the ring network. The traffic always occupies the network bandwidth, and the service cannot be converged.

Embodiment 1

[0081] Such as figure 1 As shown, the Ethernet ring network consists of 4 nodes, in which node 3 is connected to the multicast source, and ports 2, 3, 4, 5, 7, 8, 9, and 10 are ring network ports. Among them, port 6 is configured as the source port, 1 is configured as the receiving port, and 2, 3, 4, 5, 7, 8, 9, and 10 are both source ports and receiving ports. The STP status of ports 9 and 10 is block.

[0082] The user on node 1 sends a join message to join the multicast group 224.1.1.1, adds port 1 as a member port of the multicast group 224.1.1.1, and sends a join message from source port 2 at the same time; node 2 receives the join message and sends Port 3 joins the members of the multicast group, and at the same time sends join messages from source ports 3 and 4, and all interconnected ring network ports are added as member ports of the multicast group 224.1.1.1 in turn, and node 3 sends join messages to port 6 For the multicast source, make the multicast data stream e...

Abstract

The invention provides a fast convergence method and device of Ethernet ring network multicast Proxy mode business, and relates to the field of Ethernet ring networks. The method comprises the following steps: when a departure message is received, deleting a packet receiving port from a multicast group member; and checking the multicast group member, if the multicast group member only has one ring network port left, sending the departure message to the ring network port, and deleting the ring network port from the multicast group member. According to the fast convergence method and device provided by the invention, the ''ping-pong effect'' in the ring network Proxy multicast is effectively solved by processing upper nodes, intermediate nodes and edge nodes in an IGMP Proxy mechanism, and the multicast flow can be converged within a relatively short time, thereby avoiding long-term occupation of network bandwidth.

Description

technical field [0001] The present invention relates to the field of Ethernet ring network, in particular to a method and device for quickly converging services in the Ethernet ring network multicast proxy mode. Background technique [0002] The Ethernet ring network is a typical networking application of Ethernet on the metropolitan area network. It solves the problems of weak protection capability and poor recovery time of traditional data networks. reliability. [0003] The Ethernet ring network has the advantage of supporting multicast applications. The traditional data network needs to replicate the multicast stream on each downlink port of the multicast branch node, while the Ethernet ring network only needs to replicate the multicast stream once on the entire ring network. Thus, the effectiveness of multicast data flow replication is greatly improved. [0004] Such as figure 1 As shown, any node device in the Ethernet ring network (except the root node connected to...
