US 2010/0142530 A1 · Method, Apparatus, and System for Implementing Multicast Services

Abstract

A method, device and system for implementing the multicast service are provided, and the method comprises: at the ingress node and exit node of the multicast path, establishing the mapping relationship information between the original multicast address identifier of the multicast service data and the multicast address identifier inside the bearer network; when the multicast source sends the multicast service data, the ingress node maps the original multicast address identifier of the multicast service data to the multicast address identifier inside the bearer network according to the mapping relationship information, and sends the multicast service data to the exit node along the multicast path; and the exit node maps the multicast identifier of the multicast service data inside the bearer network to the original multicast address identifier according to the mapping relationship information, and sends it to the receiving side of the multicast service data.

Dependent claims

A method for implementing multicast services, comprising:

setting up a mapping relationship information between an original multicast address ID of multicast service data and a multicast address ID inside a bearer network at 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.

1 more element

A data transmission device, comprising:

an external interface module and an internal interface module, wherein the external interface module or the internal interface module is configured to exchange multicast service data with an external device and an internal device on a bearer network respectively;
a multicast address mapping receiving module, configured to receive a mapping of multicast addresses, which is a mapping between an original multicast address ID of multicast service data and a multicast address ID inside the bearer network;
and
a first multicast address mapping module, configured to convert an ingress multicast address ID of the received multicast service data into an egress multicast address ID according to the mapping information, and send the multicast service data.
