Abstract:
1. A method for implementing multicast services, comprising: setting up, by a Resource and Admission Control Subsystem (RACS) at bearer control layer, a mapping relationship information between an original multicast address ID of multicast service data and a multicast address ID inside a bearer network; sending, by the RACS, the mapping relationship information to an ingress node and an egress node of a multicast path; converting, by the ingress node, the address of the received multicast service data from the original multicast address ID into the multicast address ID inside the bearer network according to the mapping relationship information and sending out the multicast service data; and converting, by the egress node, the address of the received multicast service data from the multicast address ID inside the bearer network into the original multicast address ID according to the mapping information and sending out the multicast service data; wherein the step of setting up the mapping relationship information between the original multicast address ID of multicast service data and the multicast address ID inside the bearer network comprises: mapping the multicast address pairs to multicast address pairs inside the bearer network when multiple multicast address pairs correspond to a same multicast service package; and wherein multicast addresses in the internal multicast address pairs of the bearer network are the same.
