基于卫星广播的IP组网技术

针对采用资源预分配（PAMA）卫星信道构建IP网不能动态分配各站信道资源以及网络结构复杂的问题,提出了一种基于广播的IP组网技术。采用＂一发多收＂的通信方式,地面站以广播方式发送对其他地面站的信息,同时接收其他地面站发来的信息,保留发给本站的信息（其他信息丢弃）,实现任意2个地面站之间的双向通信。采用广播方式组网,能够减少卫星载波的占用数量,简化网络配置,提高卫星信道资源利用率。

IP Networking Technique Based on Satellite Broadcast

This paper puts forward a networking technique based on broadcasting for the situation of complex network structure and that channel resources can not be allocated dynamically in IP network constructed by SAT channels by means of PAMA. Bidirectional communication between two earth stations is realized by mode of single-transmitting multi-receiving,i. e. one earth station sending information to others by broadcasting while receiving information from others,and information for local station being stored. Networking by broadcasting can reduce occupation of satellite carrier,simplify configuration,and improve utilization of channel.
