摘　　要：研究了WDM网状网中考虑优先级的共享通路保护问题,综合考虑了负载均衡、资源利用率和路由跳数的影响因素,提出了一种新的动态共享通路保护LRP-SPP启发式算法。仿真实验表明LRP-SPP不仅能使网络业务更均衡,资源利用率更少,而且可满足不同优先级业务的需要。This paper studies the Shared-path protection with considering priority in WDM mesh networks, Consideres the impacts of load balancing, resource utilization ratio and hops of routing,and proposes a new dynamic Shared-path protection heuristic algorithm called LRP-SPP. The simulation results show that LRP-SPP not only can make the connection more balanced, less resource utilization,but also can meet the needs of the connection with different priorities.
