中文摘要：

自适应路由算法能够根据网络状态选择路径，可以最大限度地提高网络的性能。构造了一种新型的路由表，设计了基于粒子群优化的自适应网络路由算法（PSORA）。在局域网环境下，对PSORA和基于跳计数准则的RIP的模拟试验表明，在相同的网络负载下PSORA的路由表构造时间略大于RIP，但当网络拓扑变化时，PSORA的收敛速度明显优于RIP。提出的自适应的路由算法能够根据网络变化快速收敛，具有较好的应用价值。

英文摘要：

Adaptive routing algorithm can select optimal route is given,adaptive routing algorithm based on particle swarm to improve network performance up to the hih.A new routing table optimization（PSORA） is designed and realized.Simulation tests of PSORA and RIP in WAN show that PSORA take little more time than RIP in constructing router table,but it has good conver- gence rate when changing net topology in the same network load.The algorithm given in this paper has advantages of good convergence, and applying prospect.
