摘要
研究了网状WDM网中双链路失效下共享通路保护(SPP)和共享链路保护(SLP),以及新的保护方式—共享段保护(SSP)的模型,并分析了静态和动态保护算法。动态保护算法可以根据当前网络状态动态调整链路代价,使它们具有较高的资源利用率和较低的阻塞率。
We studied the shared path protection（SPP） and the shared link protection（SLP） under the condition of the double-link failures in meshed WDM networks.Furthermore,we presented a new protection method-shared segment protection（SSP） model,and analyzed the static and dynamic protection algorithm respectively.The dynamic protection algorithm can dynamically adjust link costs according to the current network status,so it has a higher resource utilization and lower blocking probability.
