[0029] Functional Overview
[0030] Considering the problem that the multicast source in the related art needs to copy multiple data streams for transmission on the PW, resulting in waste of bandwidth, the present invention provides a solution for multicast data forwarding. The processing principles of the solution are as follows: After the join request, determine the multicast VSI corresponding to the user information according to the user information carried in the join request; determine the information of all users requesting to join managed by the multicast VSI according to the forwarding table, and determine the The information forwards the multicast data from the multicast VSI to all users who request to join managed by the multicast VSI, wherein the forwarding table is used to record the correspondence between the multicast VSI and the information of all users who request to join. Through the embodiment of the invention, the bandwidth of the network can be saved and th...
