Embodiment Construction
[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0016] Embodiment 1 of the present invention describes a method for determining a multicast proxy node. The method includes the following steps:
[0017] 101. The multicast source node sends a multicast proxy node discovery request, and the discovery request carries a destination group identifier. The multicast proxy node discovery request can be sent in a broadcast form.
[0018] 102. After receiving the discovery request, the member nodes of each group determine their routing cost to the multicast source node, and then return it to the multicast source node.
[0019] Before the discovery request reaches each group member node, it usually passes through an intermediate node, which may be a group member node or a non-group member node. After a node receives the...
