摘要
ＶＳＡＴ（甚小口径终端）卫星系统是现代卫星通信领域的新技术代表，双向ＶＳＡＴ卫星系统主要用于数据传输。它是一个稀路由的分组交换网络，支持ＯＳＩ的第１，２，３层协议。由于网络有很多协议与分组包要处理，因此网络管理系统须对通讯网进行监视、控制与维护。
The two way VSAT satellite system,which is a representation of the new technique in modern satellite communication,is used mainly in the data transmission.It is a block switch network of the single pass,which supports the first,the second and the third protocols of OIS.However,due to the network is to process many protocols and block packets,the communication network should be monitored,controlled and maintained by the network management system.In this paper,the architecture of the two way VSAT network,the functions and the implementation methods of the network management system are presented.
