Embodiment 1

[0036] see figure 1 , the embodiment of the present invention provides a digital subscriber line multicast method, including:

[0037] 101: identifying a bundled digital subscriber line;

[0038] 102: Establish a multicast distribution relationship between the bundled DSL and the multicast data;

[0039] 103: Distribute the multicast data according to the multicast distribution relationship.

[0040] The method is described in further detail below:

[0041] see figure 2 , in this embodiment, the IGMP message sent by the host arrives at the network-side binding device from different uplink physical ports of the RG (Remote Gateway, remote gateway) or CPE (Customer Premise Equipment, customer premise equipment), that is, the network-side binding The device where the module MUX (multiplexer, multiplexer) / DeMUX (demultiplexer, demultiplexer) is located. The network-side binding module may be located on an IP edge device or an aggregation node (Aggressive Node). The DSLs conn...

Abstract

The invention discloses a method, a system and a device for multicasting digital subscriber lines, belonging to the technical field of communication. The method comprises the following steps: identifying binding digital subscriber lines; establishing a multicasting and distributing relationship between the binding digital subscriber lines and multicasting data; distributing the multicasting data according to the multicasting and distributing relationship. The system comprises network side binding equipment and an access node. The device comprises an identification module, an establishment module and a distribution module. By identifying the binding of the digital subscriber lines, forming the multicasting and distributing relationship for the binding digital subscriber lines, and distributing the multicasting data according to the multicasting and distributing relationship, the invention realizes the multicasting of binding subscribers, and fully utilizing network bandwidth.
