摘要

文章提出一种基于数据包频率模式-树结构（BFP-Tree）方法的负载平衡路由机制

该机制首先统计所有路径节点的使用频度;然后选取使用频度最高的节点路径

按照网络中各链路使用波长数的统计方差最小的原则

对业务请求进行路由选择。仿真结果表明:该方法在阻塞概率和传输延迟性能方面都优于BFP-Tree路由机制。

Abstract

A load-balancing routing mechanism based on BFP-Tree approach is proposed in this paper

which first counts up the use frequency of all the nodes

then chooses the most often used path and performs routing selection for the traffic request according to the principle that the statistical variance of the number of the used wavelengths for each link in the network is the minimum.Simulation results show that this mechanism is superior to the BFP-Tree routing mechanism in both blocking probability and transmission delay.
