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.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a multicast method, system and device for digital subscriber lines. Background technique [0002] The traditional DSL (Digital Subscriber Line, Digital Subscriber Line) technology uses a pair of twisted-pair wires to complete data transmission. Even if a user has more than one pair of twisted-pair wires, they can only use them independently and transmit data independently. Combined to transfer the same data at high speed. Therefore, in order to increase the user's access bandwidth, a multi-twisted-pair bundle based on a single user appears. [0003] Traditional multicast technology requires the receivers to join the IP multicast network and join the corresponding multicast group in order for the multicast packets to reach each receiver. IGMP (Internet Group Management Protocol, Internet Group Management Protocol) is a signaling mechanism for hosts to routers used by IP m...
