摘　　要：为提高电力通信网资源利用率,降低网络冗余,满足电力需求响应业务对于传输网络可靠性的要求,文章考虑需求响应的业务特性,提出一种基于报文感知的电力需求响应业务P圈保护策略(P-Cycle protection strategy for power demand response service based on message awareness,DRPS-MA)。通过负载均衡方案对网络流量进行疏导,避免网络中的业务集中至某些特定链路,可以有效降低网络阻塞,优化业务路由。保证网络可靠性的基础上通过工作路径和保护P圈联合优化算法解决需求响应业务的寻路和保护问题,为待处理的业务请求分配工作带宽和保护带宽,最大化利用网络资源。仿真结果表明所提DRPS-MA算法能够显著降低电力通信网的冗余度和阻塞率,为需求响应业务提供端到端的快速恢复。In order to improve the resource utilization rate of the electric power communication network, reduce network redundancy, and meet the requirements of the power demand response business for the reliability of the transmission network, this paper considers the business characteristics of demand response and proposes a P-Cycle Protection Strategy for Power Demand Response Service Based on Message Awareness(DRPS-MA). Through the load balancing scheme to guide the network traffic, which can avoid the concentration of services in the network to certain specific links, effectively reduce network congestion, and optimize service routing. On the basis of ensuring network reliability, the joint optimization algorithm of working path and protection P-Cycles are used to solve the problem of path finding and protection of demand response services. Allocate working bandwidth and protection bandwidth for pending service requests, and maximize the use of network resources. Simulation results show that the proposed DRPS-MA algorithm can significantly reduce the redundancy and blocking rate of protection resources in the power communication network, and provide end-to-end rapid recovery for demand response services.
