一种用于MPLS光波长路由器的自适应路由策略

A novel adaptive routing policy for photonic MPLS routers

针对现有 MPLS 光波长路由器存在 IP 层和光层分别路由的不足,提出了一种使用了联合路由算法的自适应路由策略,该路由策略可以适应流量疏导端口资源的变化,合理利用波长和流量疏导端口,提高网络性能和资源利用率。同时为了支持该路由策略,还提出了一种辅助拓扑的构造方法。仿真结果显示,该自适应路由策略具有更好的性能,可以承载更多的业务。

Considering that routing policy for existing photonic MPLS routers have defects because of the separate routing schemes for IP and optical layers, this paper proposes an adaptive routing policy for photonic MPLS routers, which adopts the integrated routing method and is capable of adapting the change of grooming ports. An auxiliary topology construction method is also proposed to support this adaptive routing policy. Simulation results show that the adaptive routing policy has a better overall performance in resource utilization.
