WDM全光网自适应路由和波长分配算法

摘要

研究了无波长转换WDM全光网的路由和波长分配算法（RWA）.通过对已有算法的分析和比较，提出了一种自适应最小跳数路由算法（ADMH）.此算法以最小跳数路由为基础，同时考虑网络状态的变化，因而不仅能尽量少使用网络资源，也能使网络资源的分布保持均衡.计算机模拟仿真的结果表明，这种算法性能在各种网络参数条件下优于或等于已有算法.%Routing and wavelength assignment algorithms for NCWDM all-optical networks are studied in this paper. Through analysis and comparison, a new adaptive dynamic minimum-hop routing algorithm (ADMH) is proposed. The algorithm is based on DMH and takes the network statement into consideration, so that it can not only use network resources as little as possible but also keep the network resources as balanced as possible. The simulation results show that the performance is good than or equal to some existent algorithms for different network parameters.
