摘要 对波分复用(Wavelength Divisi on Multiplexing,WDM)网状网中的动态域间流量疏导问题进行了深入研究.在源路由模式下,提出了一种基于固定备选路由方式的动态域间流量疏导算法,并在其基础上提出了只考虑波长均衡和同时考虑波长均衡与业务均衡的改进方法.该算法可以有效地避免路由环,得到较低的阻塞率,节省全网的收发器数目和波长资源.仿真结果表明,这种算法可以有效地改善网络性能. The dynamic inter-domain traffic grooming problem in WDM（wavelength division multiplexing） mesh optical networks is investigated. Based on source routing, a dynamic inter-domain traffic grooming algorithm with two improved methods using the fixed alternate routing （FAR） is proposed. The average block probability can be reduced ,and the routing loops can be avoided efficiently and the network resources （wavelength and transceiver） can be saved by the proposed algorithms. The simulation results show that the network performance can be improved significantly by these algorithms.
