Method for Optimizing Multicast Group 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.

1. A method for optimizing multicast group, comprising:
identifying, by an anchor, a set of nodes requesting for the same multicast group data and sharing the same Access Gateway (AG) in a multicast group, wherein the set of nodes comprises at least two nodes requesting for the same multicast group data and sharing the same AG; transmitting, by the anchor, the same multicast group data to each node in the set of nodes via the same AG.
