摘要
如何实现全网负载平衡一直是卫星网路由策略的难点之一。首先,根据路由策略运行位置将非静止轨道IP卫星网路由策略研究成果分成了源路由、集中式、分布式和层次式路由;然后,系统阐述了各路由策略的主要思想,对比分析了其优缺点;接着讨论了与非静止轨道卫星网负载平衡路由策略相关的一些关键问题;最后指出了设计非静止轨道卫星网负载平衡策略应考虑的几个主要方面。
How to achieve load balancing over satellite networks is one of several difficulties during designing satellite routing strategies. Firstly,routing strategies for Non-Geostationary Earth Orbit (Non-GEO) satellite networks are classified into four categories according to the place where the routing is performed:source-based, central ,distributed,and hierarchical load balancing routing. Secondly, main ideas are illustrated systematically and their advantages and disadvantages are discussed. Thirdly,several key issues about load balancing of Non- GEO satellite networks are given. Finally, some further research aspects are pointed out.
