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...
