文章主要研究WDM（波分复用）光网络中动态业务流量疏导的选路算法，提出了基于拓扑融合的动态流量疏导算法。该算法的最大特点在于融合了物理拓扑及其抽象出来的虚拓扑，利用最小权重优先方法进行选路。仿真结果表明,该算法在不增大建路时延的基础上，可以有效提高资源利用率，降低阻塞率，尤其是在高负载情况下，效果显著。

This paper mainly studies on the route selection for the dynamic traffic grooming in Wavelength Division Multiplexing (WDM) optical networks and proposes a topology-integration-based dynamic traffic grooming algorithm. Its most important feature is merging physical topology and virtual topology and using the minimum-weight preferred method for route selection. Simulation results show that this algorithm improves resource utilization and reduces congestion rate without increasing link-setup delay, especially effective in high load conditions.
