摘要 文章研究了WDM光网络中动态业务下的波长分配问题,提出了一种改进的动态门限算法。该算法不仅能保证高优先级的请求有较低的阻塞率,同时还能优化低优先级请求的阻塞率,从而改善全网的平均阻塞率。此外,该算法利用相对最小影响算法,能更加精确地描述波长分配对全网状态的影响,从而更加有效地利用了网络资源。计算机仿真表明,该算法性能较好。 In this paper,a novel heuristic algorithm is proposed for dynamic wavelength assignment in WDM networks without wavelength conversion.It not only guarantees the lower average blocking rate,but also can make network resources utilized more efficiently.Simulation results show that the proposed algorithm performs better than other algorithms.
