Analysis of QoS Requirement of Satellite Network Satisfying Applications Demands of Users and Tasks
满足用户与任务应用需求的卫星网络服务质量QoS需求分析

In this paper,QoS(Quality of Service)requirements of satellite network satisfying applications demands of users and tasks are analyzed in order to support the design and construction of satellite network satisfying applications demands.At first,the characteristic of architecture and operation of satellite network is analyzed,then the key QoS in- dexes satisfying applications demands of users and tasks such as delay and delay varying are analyzed emphatically,in- cluding the reason and type of forming,affections to communication in satellite network,steps of improving,etc.At the end,the cooperation satellite network that is composed of GEO/MEO two-layer satellite constellations and terres- trial is proposed on the based of the design and construction requirement of space-based warn system.
