路由算法的优劣直接影响到通信网络的性能。传统的卫星路由算法基于最短路径算法，单纯考虑时延最小、跳数最少或链路带宽利用率最佳。针对信息网络的实时性要求，提出了一种综合考虑卫星链路间时延和带宽的路由算法BDSR （bandwidth-delay satellite routing）。并在NS2仿真平台上证明了该路由算法是一种理想的、适用于LEO卫星网络的路由算法。
The merits of the routing algorithm will have a direct impact on the performance of a communication network. Traditional satellite routing algorithms are based on shortest path algorithm, the simply considering least delay, the least hop or the best link-bandwidth utilization. For the request of real-time in information network, a routing algorithm BDSR (bandwidth-delay satellite routing) comprehensively considering both delay and bandwidth between satellite-link is proposed in this paper. Moreover, we prove that the routing algorithm is an ideal one that is suitable for LEO satellite network on NS2 simulation platform.
