对具有业务流量疏导能力的WDM(波分复用)网状网进行了深入的研究,提出了2种基于固定备选路由的动态流量疏导算法,其可以在路由预计算的过程中考虑疏导业务的均衡,得到较低的阻塞率,而且具有较低的时间复杂度.仿真结果表明,这些算法可以有效地改善网络性能.
The traffic grooming problem in wavelength division multiplexing(WDM) mesh optical net- works was investigated. Two dynamic traffic grooming algorithms using the fixed alternate routing (FAR) were proposed. The average block probability could be reduced by pre-balancing the traffic in the network, and lower time complexity could be acquired simultaneously with the algorithms. The simulation results show that the network performance can be improved significantly by these algorithms.
