摘要
以卫星数据广播作为背景,设计一个基于UDP/IP的数据传输协议。由于卫星传输网只支持网络层以下各层的数据包传送业务,传输协议的设计将重点放在传输层和应用层。传输层采用UDP协议,是因为目前卫星数据广播大都是单工通信方式,只能采用UDP进行传输;应用层采用类FTP协议,实现断点续传机制。最后通过一个软件在局域网内模拟卫星数据广播,对该协议进行了测试。
In this paper,a reliable data transfer protocol based on UDP/IP for the Satellite Broadcasting environment is addressed.Since the satellite transmission network can only transfer the data below the network layer, concentration of the protocol design is the transport layer and application layer.Satellite Broadcasting provides simplex communication mode,so UDP protocol is chosen in the transport layer and the FTP-like is used in the application layer.The protocol was validated in the LAN simulating the Satellite Broadcasting Environment.
