摘要
卫星综合信息网是一种天地一体化网络,是卫星通信与传统网络技术融合的必然发展趋势.空间中的卫星以及星地通信链路都是高成本的网络资源,如何充分利用有限的网络资源、保证服务质量则是研究这类网络时必须考虑的问题.本文为解决这一问题,提出了卫星综合信息网服务级管理的体系结构,并着重对服务拓扑管理、服务一致性管理进行了深入的研究,同时概括性的提出了服务安全管理和服务故障管理的模型.文章最后建立了卫星综合信息网服务级管理演示验证系统,对文中提到的服务拓扑算法的有效性进行了验证.
Integrated Satellite Information Network （ISIN） includes those nodes in space and those on ground. It is the way to realize fusion of satellite communication and traditional network technology. The satellites in space and the communication links between the satellites and ground nodes are expensive network resources, so it is very important to make full use of that in order to guarantee quality of service. In this paper, architecture of service level management in ISIN is proposed, and service topology management and service level agreement are deeply researched as well as service security management and service fault management are briefly discussed. At last, the simulation system of service level management applied to ISIN is accomplished and service topology algorithm is validated.
