Problems solved by technology

However, using this method to realize the forwarding process of multicast services is relatively complicated, the forwarding efficiency is poor, and a Layer 2 switching domain must be configured, the configuration process is complicated, and it is not suitable for large-scale networking requirements; because the existing Ethernet technology is a connectionless However, there is not enough QoS (Quality of Service) processing capability, so this method cannot provide good QoS support for multicast services

Embodiment Construction

[0050] The core of the present invention is: to establish multicast data messages from the source end network node based on the multi-service transmission platform to a plurality of destination end network nodes label switching path multicast tree, source end network node according to the label switching path multicast tree The multicast data message is transmitted to each destination network node.

[0051] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0052] The unicast LSP (Label Switching Path) is a point-to-point data transmission tunnel established between the source network node and the destination network node. When the present invention uses the LSP to transmit the multicast data message, according to the group The broadcast data message needs to be transmitted from the source network node to each destination network node to establish an LSP multicast tree from the source ne...

Abstract

This invention provides a multicast realizing method on a multi-service transmission platform, which sets up a label exchange path multicast tree between a source network nexus and multiple destination network nexuses based on the multi-service transmission platform, so that, the multicast data messages from the source network nexus to multiple destination network nexuses is realized based on the label exchange path multicast tree and the process of multiple forward of multicast data messages from network nexuses is simplified.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing multicast based on a multi-service transmission platform. Background technique [0002] In the construction and operation of broadband networks, it is an indisputable fact that business is the forerunner and the core. At present, with the growth of people's demand for video services, the multicast service has developed rapidly as the best way to support video services, and the multicast service is one of the services with the greatest development potential in the future. [0003] The rapid development of multicast services has put forward new requirements for network operations. On the one hand, the network is required to provide higher transmission bandwidth; on the other hand, the network is required to provide effective, operable, and manageable support for multicast services. . [0004] As one of the main carriers of service transmission...
