基于MTN小颗粒通道技术的电力通信CBR业务承载管控模型研究OA

At present,there are a large number of constant bit rate(CBR)services in the power communication network.Against the backdrop of traditional network equipment such as SDH/MSTP facing network retirement and the urgent need to upgrade and evolve the bearer network technology,it is necessary to solve the problem of carrying and controlling power CBR services in the new technological route.This paper first introduces the technology scheme of CBR service bearing and forwarding surface based on the small particle channel technology of metro transport network(MTN).On this basis,a new"centralized SDN+distributed control"model architecture for power CBR service carrying is proposed.In response to the high latency stability requirements of power CBR service,the processing and channel path allocation mechanism of CBR service are optimized.Based on this optimization method,the simulation design of optimal channel path planning is carried out.The results show that the proposed control model architecture and method can optimize the processing and path calculation effect of CBR service and have good scalability.
