摘要
将链路波长使用数均衡的负载平衡思想引入到光网络恢复机制中,同时区分业务的可靠性,提出基于负载平衡的通路恢复算法。仿真表明,该算法不仅降低了全网阻塞率,而且能保证较高优先级的光路建立请求具有较低的阻塞率,更适合现代光网络中不同业务请求对应不同服务等级的要求。
The load balance theory that link wavelength uses number convergence is introduced in optical network recovery mechanism and business reliability is distinguishes, then the restoration algorithm of WDM network is propsoed in this paper. Simulation results shows that the algorithm can reduce blocking probability of the whole network, and ensure a high-priorith request with a low blocking rate. The algorithm is more suitable for requirements of modern optical networks.
