摘　　要：IP/DWDM网络的综合路由中的一个重要的研究问题就是如何对跨越不同DWDM网络的IP路由进行综合路由,特别是当两个DWDM网络的容量设置不同时。本文着重解决的就是如何对从单波长带宽大的网络进入单波长带宽小的网络传输的IP业务的综合路由问题。根据尽量鼓励对波长链路的带宽进行完全使用,以减小波长链路带宽碎片的原则,我们提出了两种解决算法:1+n 算法和 m+n算法。仿真结果对两种算法的效率和性能进行了测试。One of the key issues in integrated dynamic IP and wavelength routing algorithm is the routing issue of IP traffic from one DWDM network to another DWDM network with different network capacity, especially how to route the IP traffic flow or request from a DWDM network with larger per-wavelength bandwidth to the DWDM network with smaller per-wavelength bandwidth. We define the IP traffic flow that required bandwidth is larger than the bandwidth of a wavelength capacity of the network as larger traffic first, and address the integration routing issue of large traffic in IP/DWDM network. Based on the principle of improving the logical link utilization, integer wavelength is encouraged to use. Then two basic methods are proposed: 1+n and m+n. Simulation results illustrate the effect of the two methods.1
