多域光网络 路径计算单元 域间输出策略 分段共享保护 multi-domains optical mesh networks PCE export policy segment-shared protection
摘要
研究了多域光网络中的路由保护问题。在多域光网络中, 域间路由的建立要遵从域间输出策略。在考虑域间输出策略的基础上提出了一种多域光网络中基于路径计算单元的分段共享保护算法。仿真表明, 相比传统的基于路径计算单元的多域分段保护算法, 该算法阻塞率低, 平均保护切换时间短。
Abstract
It is investigated the dynamic survivable routing problem in multi-domain WDM optical networks. Based on the path computation element (PCE) architecture, it is proposed an export policy constrained segment-shared protection approach which is called EPCSSP. Under dynamic traffic with different loads, the simulation results show that the proposed scheme is effective in multi-domain path protection with lower blocking probabilities and shorter average recovery time.
