| 摘 要： | 提出了一种基于边界路由器的远程路由计算和查找方法，以边界路由器为核心计算远程路由信息，查找时通过路径长度比较实现最短路径的选择。该方法有效降低了远程路由表规模，提高了并行模拟器的运行效率。与PDNS相比，远程路由表规模缩减90％，初始化占用内存节省约20％，模拟运行时间减少25％。

| Abstract: | A new method which computes remote routing based on the border routers,was presented and finds the appropriate route by comparing the length of routing.It effectively reduces the size of remote routing table,and improves the efficiency of network simulation.Compared with PDNS,it reduces 90 percent of the size of the remote routing table,saves 20 percent of the memory needed during the initialization,and 25 percent of the simulation time. |
