摘　　要：提出了一种新的基于OSPF的ASON路由实现方案,扩展了波长链路状态公告和网络节点链路状态公告,用于在全网分发波长和网络拓扑信息。实现了拓扑的自动发现和路由信息的可靠分发,并提供了友好的RWA接口以便引入各种RWA算法和动态连接建立信令协议。通过仿真对本方案进行了验证,比较了若干RWA算法的性能,分析了两类路由信息更新触发策略和在全网分发波长信息的可行性。An OSPF-based ASON routing implementation was proposed. In the implementation a wavelength LSA and network node LSA were extended to distribute wavelength and topology information. The topology was discovered automatically and routing messages were delivered reliably. In addition, the RWA interface was designed to introduce RWA algorithms easily. The simulation results show that the routing protocol implementation could converge rapidly and could be extended easily at low protocol overhead. The routing information flooding trigger strategies and the feasibility of flooding wavelength information throughout the network are also analyzed.
