摘要
为研究空间通信网络的可靠性,首先介绍了空间通信环境特点及通信网络的可靠性理论基础,然后讨论了通信网络的可靠性评价指标,包括抗毁性、生存性、有效性及其计算方法。由于网络可靠性评估涉及的因素较多且相互影响,采用建立网络可靠性模型方法以研究网络部件失效及修复的情况,应用概率分析方法得到系统可靠性的数学模型,并给出了系统可靠性与节点和链路可靠性的关系,可供空间网设计参考。
In order to research the reliability of the space communication network, the paper firstly introduces the charac- teristics of space communication environment and the theoretical basis of the reliability in communication network. Then the specifications for evaluating and calculating the reliability of communication network, including invulnerability, survivability and effectiveness, are discussed. Due to many factors to assess the network reliability involved and their interacts on each oth- er, it is necessary to establish a network reliability model to determine the network component failure and repair situations. In this paper, the probability analysis method is used to get the mathematical model of system reliability and its relationship with node and link reliability is discussed. The research results have a reference value for the design of space network.
