摘　　要：由于电力行业的特殊性,承载其业务传输的电力通信网的可靠性逐步受到了重视,随着电力通信网架建设不断完善,网络逐渐表现出垂直分层化的特点,使得跨层联合保护成为可能。文中针对电力通信网设计了一种基于网络编码的跨层保护策略(CLPBNC)。在IP层利用网络编码为链路提供保护,在光传输网中利用预置圈恢复链路故障,并研究跨层联合保护的条件,进而提高保护效率。仿真结果表明,CLPBNC可以有效降低保护冗余度,提高保护效率进而优化网络的整体性能。Due to the particularity of power industry,the reliability of power communication network carrying its business transmission has been paid more and more attention.With the continuous improvement of the communication network structrue,the network gradually presents the characteristics of vertical layering,which makes cross-layer joint protection possible.A cross-layer protection based on network coding(CLPBNC)strategy is proposed for power communication network.In IP layer,network coding is used to protect links.In optical transmission network,preconfigured cycle(P-cycle)is used to recover link failure.And conditions of cross-layer joint protection are studied to improve protection efficiency.The simulation results show that CLPBNC can effectively reduce the redundancy of protection,improve the efficiency of protection and optimize the overall performance of the network.
