基于容量的相对最小影响资源分配算法

Capacity Based Relative Least Influence Resource Assignment Algorithm

在对现有的波长资源分配算法进行了研究和分析的基础上,提出了一种基于容量的相对最小影响波长资源分配算法.该算法通过定义基于容量的影响因子,分析受当前波长分配影响之后各路径在各波长上的可用信道数,更为精确地描述了当前分配波长对于受影响路径的路径容量产生的影响.仿真结果表明,新的算法降低了网络阻塞率,提高了网络资源利用率.

The capacity based relative least influence （CBR） wavelength resource assignment algo-rithm is presented based on the research and analysis of existing algorithms. The CBR analyzes the influence on channel numbers of each paths at each wavelength after current assigning wave- length through defining capacity based influence factor. So the influence about influenced paths capacity from current assigning wavelength more accurately can be described. Simulation shows that the new algorithm will reduce the blocking probability and improve the utilization ratio of network resource.
