摘要(Abstract)：

有向网络中,最短路径的计算在交通、通信等实际问题中有着重要的应用.通过对现有动态最短路径算法的深入研究,提出一种处理网络拓扑变化的全动态最短路径算法(Increase or Decrease of Edge Weight for Shortest Path Tree,IDEWSPT).该算法利用初始最短路径树(Shortest Path Tree SPT)的信息,建立一个SPT的更新队列,当网络拓扑发生变化时,将更新范围局限在受拓扑变化影响的节点中,从而达到控制冗余更新的目的.算法复杂度分析和仿真结果显示,IDEWSPT算法具更高的时间效率.

关键词(KeyWords)： 最短路径;SPF算法;动态更新路由协议
