摘    要:对目前几种主流的组网技术,包括异步传输模式(ATM),网际互连协议的协议栈(IP),多协议标签交换(MPLS),卫星网络与地面网络的网络构成、拓扑以及通信时延等特点作了分析比较,同时对地面网络上的主要的路由算法进行了分析,主要包括距离向量算法和链路状态算法等:给出了运行于卫星网络上的路由算法,并对路由算法的三种策略进行了分类分析,其中基于虚拟拓扑路由策略的路由算法多用于基于像ATM等面向连接的网络;而采用虚拟节点概念的路由算法常用于基于IP的路由;基于拓扑依赖策略的路由算法,对于特定的星座网络将会有较高的效率。

关 键 词:体系结构  路由算法  通信时延  卫星网络

Abstract:Analyses and compares several main techniques of constructing a network, including asynchronous transfer mode (ATM), IP protocol suite, multi-protocol label switching(MPLS), and the network components, topology and communication's time delay between satellite network and ground network. In succesion, the paper analyses the main routing algorithm of ground network, including distance vector algorithm and chain state algorithm. At last the paper presents the routing algorithms which are runing on the satellite network.It sorts and analyses the three tactics of routing algorithm. Thereinfo, a routing algorithm based on virtual topology routing rule is more used in the connected network like ATM network etc; a routing algorithm based on virtual node conception is often used in the routing based on IP network; a routing algorithm based on topology dependency tactics will generally have higher efficiency for special constellation network.
Keywords:network system structure  routing algorithm  communication's time delay  satellite network
