摘要(Abstract):
电力业务因其行业特殊性,承载其传输的电力通信网的生存性逐步被重视。该文为了提高电力通信网络的可靠性研究了P圈(preconfigured cycle,P-cycle)在电力通信网中的应用,提出了一种考虑链路风险的保护策略(riskconsidered link protection strategy,RCLPS)。首先对链路失效风险进行建模,随后针对P圈的物理结构限制及链路风险对电力业务进行负载均衡(load balance, LB),将网络中的业务向风险较低的链路上进行疏导,并且使网络中的业务分布更加有利于使用P圈进行保护,从而提高保护效率和网络资源利用率。仿真结果表明,RCLPS算法可以有效降低保护冗余度,并可以实现对网络中资源的高效利用。
