摘    要:在LEO卫星网络中,由于卫星高速运动导致的网络拓扑变化和不同卫星覆盖城内流量的非规整性给设计其特殊路由算法带来很大挑战。结合卫星网络的固有特点,本文提出一种基于路径信息压缩的分布式路由算法CPDR(Compressed Path Information based Distributed Routing)。该算法使用分布式分层链路状态收集策略和简洁的路径信息编码机制,能够在不引入额外信令开销基础之上提供多路径路由能力,实现卫星网路中的流量负载平衡、优化网络带宽应用、提高星际链路利用率。

关 键 词:卫星网络  路由算法  链路状态  路径信息压缩

Abstract:Due to high-speed movement of satellites around the regions, the dynamic topology of LEO satellite networks and earth and temporal variation of traffic intensity in certain variable traffic load in different satellite coverage areas pose special requirements to routing in ISL segment of network. Considering inherent characteristic of LEO satellite networks, a compressed path information based distributed routing algorithm is proposed in this paper. The algorithm can support multi-path routing capability without introducing additional signal overhead by using a distributed hierarchical link state collection policy and a compact path information coding scheme, so as to realize traffic load balancing and optimize utilization of costly spatial network resources.
Keywords:Satellite network  Routing algorithm  Link state  Path information coding
