摘要
设计了一种基于拓扑变化预计算的多层卫星网络路由协议。与已有协议不同,该协议在网络拓扑变化前完成路由计算,并采用了自适应的链路状态报告方式。从路由计算时机和链路状态报告方式2方面分析了协议的合理性。与常规路由协议相比,此路由协议收敛更快,更能适应多层卫星网络拓扑变化频繁的特点。
A novel routing protocol based on topology precomputation is proposed. Unlike protocols, the link status reporting manner of this protocol adotps self-adapting report method existing and the route computation is accomplished before topology changes. The rationality of this protocol is analyzed from the moment of routing computation and the manner of link status reporting. Compared with conven- tional routing protocols, this protocol converges more quickly and is more adaptable to multilayer satellite networks, of which the topology changes frequently.
