摘要

链路保护方案以非常有限的信令量提供高光路可用性。当这些保护方案应用于具有p周期的网状网络时,也可以在故障检测后50毫秒内达到服务恢复。在本文中,我们比较了专用和共享链路保护方案在基于网格的ASON/GMPLS网络具有定义的p-环。在交通容量和光路可用性方面进行了比较。讨论了计算光路可用性的解析模型。

Capacity and availability comparison of OMS protection schemes in ASON/GMPLS mesh networks
Link protection schemes provide high lightpath availability with very limited amount of signaling. When these protection schemes are applied over mesh networks with p-cycles it is also possible to reach service recovery within 50 ms after failure detection. In this paper we compare dedicated and shared link protection schemes over mesh-based ASON/GMPLS networks with defined p-cycles. The comparison is performed in terms of traffic capacity and lightpath availability. An analytical model to calculate the lightpaths availability is also discussed.
