Embodiment Construction

[0059] The implementation of the technical solution will be described in detail below in conjunction with the accompanying drawings.

[0060] The method described in this discovery is based on implementing the user group management of the optical network through the service management module of the management plane or the UNI-N (user network interface network side) equipment of the control plane, and adopts the optical network management plane based on the management plane and the control plane. The multicast mechanism, through the dynamic establishment of multicast routes, the addition and deletion of leaf nodes, the link summary, and the method of establishing connections one by one, can save a lot of path establishment and bandwidth when the network scale is relatively large, and can avoid network scale. Problems such as waste of resources brought about by the increase, greatly increase the efficiency of multicast optical network establishment and management, increase servic...

Abstract

A method for realizing light multicast in intelligent light network includes forming user group management base by utilizing service management module in management layer; applying light multicast mechanism managed by management layer and control layer and utilizing manner of dynamically setting up multicast route, adding and deleting leaf node, summing ¿C up link and setting up connection one by one to achieve light multicast on large network for saving a lot of routes and bandwidth.

Description

technical field [0001] The invention belongs to the communication field, in particular to a method for realizing multicast group establishment and fully utilizing link resources in the field of intelligent optical networks. technical background [0002] With the continuous deepening of data transmission requirements, the transmission network system is constantly developing, and related technologies are also developing rapidly. In fact, the transmission network architecture based on the automatic switching optical network creates conditions for the provision of new services and promotes the evolution from the transmission network to the service network. With the development and research of automatic switching optical network technology, operators widely request to support the provision of new services such as OVPN (Optical Virtual Private Network, Optical Virtual Private Network) and BOD (Bandwidth on Demand), thereby promoting the provision of various new services Modes are...
