Abstract

In the existing GMPLS-based distributed control switching network, each network node needs to bear the traffic pressure, not only to calculate the service transmission path, but also to be responsible for data forwarding. In software-defined networking (SDN), the control plane is decoupled from the forwarding plane, which simplifies the network structure and facilitates network maintenance and management. The multi-granularity network is combined with SDN, and the stateful PCE is used as a controller of the network control plane to implement soft control of the network and ensure that the information of the network traffic is controlled in real time. The standard PCEP protocol is extended to add optical code granularity and CGRE (Code Group Routing Entity) related messages, making it suitable for code group switching networks, thereby enabling network services to be transmitted more efficiently and intelligently.
