Embodiment Construction
[0036] In order to solve the problem in the prior art that when the multicast group and its multicast member relationship change, the data sent by the multicast network convergence process occupies a large bandwidth, the embodiment of the present invention provides a multicast network convergence method. Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:
[0037] Such as figure 2 As shown, the method for multicast network convergence provided by the embodiment of the present invention includes the following steps:
[0038] Step 201, when a multicast group or a multicast member in the multicast group leaves, the node connected to the multicast forwarding device where the multicast group is located sends a Global Leave message to all groups in the multicast forwarding device broadcast group;
[0039] The nodes can be, for example figure 1 The shown user host, or access node (for example: base station and access gatewa...
