中文摘要：
研究了多域光网络中的路由保护问题。为了避免多域光网络通路保护二步算法可能导致的多域陷阱问题,提出了一种基于Suurballe算法扩展的多域联合路由保护算法。仿真表明,相比传统的多域通路保护二步算法,该算法资源利用率高,阻塞率低,平均每连接跨域数小。
英文摘要：
The dynamic survivable routing problem in multi-domain WDM optical networks is investigated. In order to find a solution in a trap topology, an effective multi-domain joint routing protection algorithm based on expanding Suurballe＇s algorithm, called MDJRA, was proposed. Simulations show that the proposed scheme is effective in multi-domain path protection with more efficient resource utilization, lower blocking probabilities and less inter-domain cost.
