本文采用统计的方法对以网络最小所需波长数为优化目标的路由和波长分配算法进行了修正.数值模拟计算表明
经过统计方法修正之后
可以求得更接近波长下限的网络所需波长数.另外本文还首次提出用统计的方法对路由和波长分配算法进行比较
通过比较两个算法在经过统计修正之后求得的网络所需波长数的分布可以知道它们的优劣.
In this paper
a statistical method is proposed to modify the routing and wavelength assignment (RWA) algorithms whose optimum object is the minimum number of wavelength required (MNWR) in wavelength division multiplexing all optical network.With this statistical method
a smaller NWR can be acquired through numerical simulation.And
it is the first time that the statistical method is proposed to compare the performance of different RWA algorithms.Two RWA algorithms can be compared by contrasting the distribution of the NWRs obtained by each RWA algorithm.
