DVB-RCS卫星互动网络的研究

Researching of an interactive network via satellite DVB-RCS

DVB-RCS卫星互动网络,应用前景广阔。DVB-RCS标准是为了在单向的卫星广播网络中(DVB-S)实现双向互动网络而采纳的一系列技术规范,但标准中仅规定了空中接口,没有提到如何实现一个网络的MAC接入层。卫星网络的实现结构是其MAC接入层协议的重要组成部分。本文设计了一个DVB-RCS卫星互动网络的网络结构,重点解释了它的多址接入方式和资源分配方式,最后描述了它的入网过程。

A Network via satellite DVB-RCS is booming in Satellite communication. DVB-RCS standard is proposed for turning the DVB-S broadcasting network into an interactive network. DVB- RCS only defines the air interface. VSAT network is a bidirectional communication network. In this paper, basing on the researching of VSAT network, it designs a network framework for the interactive network via satellite DVB-RCS and explains its multiple-address method and resource allocation. At last, this paper shows a description about logon a DVB-RCS Satellite Network.
