卫星通信中心站在资源池化架构下的系统可靠性分析

卫星通信中心站是卫星通信系统中的核心组成部分,既担负着网系管理的控制功能,又承载了地面网络接入的业务职能。它的系统架构可靠性的高低将直接决定整个卫星通信系统的运行是否稳定,所以可靠性同通信效能、经济成本一样,已经成为衡量中心站性能的一个重要指标。因此,针对中心站现有“烟囱”式架构下存在的问题,介绍一种基于资源池化的解决方案,并通过对两种系统架构可靠性的对比分析,证明了基于资源池化的系统架构具有更高的可靠性。

System Reliability Analysis of Satellite Communication Center Station under Resource Pooling Architecture

Satellite communication center station,as a core part of satellite communication system,bears the control functions of network management,and also carries the business functions of ground network access.The reliability of its system architecture will directly affect the normal and stable operation of the whole satellite communication system.As a result,reliability,like communication efficiency and economic cost,has become an important index to measure the performance of central station.Therefore,aiming at the problems existing in the present“chimney”architecture of the central station,a solution based on resource pooling is proposed.Comparative analysis of the reliability of these two system architectures indicates that the central station based on resource pooling has even higher reliability.
