摘要
提出了一种用于波分复用(WDM)网络中的新型自适应路由算法。引入蚁群算法解决动态路由问题,通过改进寻路中链路综合权重的设置、优化蚁群寻路的原理以及考虑波长优先级来设计算法。仿真结果表明,这种算法对光通道建立比较有效,使用这种算法,不仅可以使拥塞率更小,负载分布也更加均衡。
In this paper, a novel adaptive routing algorithm is introduced for WDM optical networks. The ant colony algorithm is adopted for dynamic routing assignment. And the novel algorithm is designed based on the load balancing strategy and on improving the set of the link weight and the wavelength priorities. The simulation results show that the novel algorithm improves the average blocking probability and the degree of load balance.
