摘　　要：为实现卫星网络的智能、自主管理,建立了一个新的基于策略的分层分布式的卫星网络管理体系结构,提出在策略执行点与全局策略服务器之间增加域策略服务器和本地策略服务器两个新的策略层的方法。该方法将域策略决策点、本地策略决策点分别放置在分管理站和具有管理功能的管理星上,实现了策略的分层管理。仿真结果表明,该卫星网络管理体系结构降低了策略执行点请求重复策略的传输时延,提高了卫星网络管理的效率.In order to accomplish the intelligent management and self-management of the satellite network,a new hierarchical distributed architecture of policy-based satellite network management is established. In the system,two new policy layers called domain policy server and local policy server are added between the policy enforcement point and the global policy server. The domain policy decision point and the local policy decision are seperately placed in the sub-management center and satellite with management functions,so the hierarchical policy management is implemented. The simulation results show that the transmission delay caused by the repeated policy request of the policy enforcement point is reduced in the new architecture,so the efficiency of the satellite network management is improved.
