Method and apparatus for classifying querying nodes

本发明公开了一种用于对查询节点分类的方法，包括：从该节点接收查询消息；检查该查询消息；当该消息是第一消息类型，并且节点未被分类或被分类为第二节点类型，就将该节点分类为第一节点类型；以及当该消息是第二消息类型并且该节点未被分类，就将该节点分类为第二节点类型。本发明还公开了一种用于对查询节点分类的装置。 Method and apparatus for classifying querying nodes.

Zusammenfassung:	本发明公开了一种用于对查询节点分类的方法，包括：从该节点接收查询消息；检查该查询消息；当该消息是第一消息类型，并且节点未被分类或被分类为第二节点类型，就将该节点分类为第一节点类型；以及当该消息是第二消息类型并且该节点未被分类，就将该节点分类为第二节点类型。本发明还公开了一种用于对查询节点分类的装置。 Method and apparatus for classifying querying nodes. A querying node is classified as a multicast router if it transmits a multicast routing protocol query message and the node is either unclassified or classified as a multicast querier. The node is classified as a multicast querier if it transmits a multicast group query message and the node is unclassified. IGMP multicast group membership reports are transmitted to both multicast queriers and multicast routers. IP multicast routing protocol data packets, however, are transmitted to only multicast routers.
