MULTICAST GROUP OPTIMIZATION METHOD AND ANCHOR |
摘要 |
Provided are a method for optimizing the multicast group and an anchor. A set of nodes requesting for the same multicast group data and sharing the same Access Gateway (AG) is identified in a multicast group, and the same multicast group data is transmitted to each node in the set of nodes via the same AG, thereby forwarding multicast data to different nodes via the same gateway, saving traffic of a network side, and optimizing the multicast group. In addition, the node optimization method allows the anchor to optimize multicast routing of the nodes requesting for the same multicast group data and sharing the same AG to the same shared gateway for forwarding if a node has a plurality of access interfaces in the present application, thus reducing unnecessary multicast routing, reducing the scale of a multicast forwarding tree, and reducing waste of network resources of the network side to the largest extent. |
