光纤通道主交换机选举算法的优化

为了消除现有选举算法中因选举优先级设置不当而造成的选举时间长、网络流量大等问题，提出一种光纤通道主交换机选举优化算法。在交换机中保存了其他交换机优先级信息的前提下，通过建立选举时间优化函数模型和消息传递数目与节点数目的映射关系模型，降低选举时间开销，减少网络通信流量。仿真实验结果表明，与原算法相比，该算法的选举时间减少了30%，消息传递数目减少了50%，有效缓解了网络延迟与拥塞。

Optimization of Principal Switch Selection Algorithm in Fibre Channel

In order to eliminate the problems in existing principal switch selection algorithm with long selection time and heavy network trafficbecause of ignoring priority, this paper gives an optimized principal switch selection algorithm.On the basis of that each switch save other switch'spriority, by building of selection time's optimized function model and the relation model between message number and node number, selection timeand network traffic are lowed.Simulation indicates that compared with other algorithm...
