Abstract: 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.

Abstract translation: 提供了一种用于优化多播组和锚的方法。 在多播组中识别请求相同组播组数据并共享相同接入网关（AG）的一组节点，同一组播组数据通过相同的AG被发送到该组节点中的每个节点，从而转发组播 通过同一个网关向不同节点发送数据，节省网络流量，优化组播组。 另外，节点优化方法允许锚点优化节点的组播路由，请求相同的组播组数据，并且如果节点在本应用中具有多个接入接口，则将相同的AG共享到相同的共享网关进行转发。
