Abstract

Abstract: The architecture of satellite communication networks based on GEO/LEO constellations is presented considering the optimizationof network management.Management subnet and service subnet are separate physically in this architecture，which makes centralized routing strategy more adapted than that in terrestrial networks.In order to strengthen the reliability of the architecture，spare routing strategy decreasing computation load is constituted making use of the characteristics of satellites’ regular movement and regular array of Inter Satellite Links（ISL）.At last the performances of two routing strategies are validated through simulations.

Key words: satellite communication, routing, network management

摘要： 从优化卫星网络管理的角度，提出了GEO/LEO卫星通信网络体系结构，该结构将管理子网与业务子网在物理上相互分离，体现了与地面网络不同的集中式路由策略的优势，同时利用卫星运行的规律性和星际链路分布的规则性，制定了极大降低运算量的备用路由策略，保证了GEO/LEO卫星网络体系结构的可靠性，通过仿真验证了两种路由策略的性能。
