A Distributed Routing Algorithm for LEO Networks
LEO卫星网络中的一种分布式路由算法

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.
