摘要
UDP是一种实时性很强的网络通信协议。针对遥操作数据传输中数据乱序、丢包的问题以及传输的数据种类多、传输需求不同的特点,在UDP协议的基础上做了添加和改善,解决了UDP无法保证数据传输质量的问题,使传输协议可以根据不同的数据类型灵活地选择传输控制策略,同时又保留了UDP本身具有的传输速度优势。在实际的数据传输实验中,验证了对协议修改的有效性。
UDP is a kind of real-time transport protocol. Considering the problem of packet disorder and packet dropout in data transmission, and various data in transmission, as well as their different demand for transmission of teleoperation, improve- ment is made to ensure quality of data transmission in teleoperation, and to make it possible for protocol to choose strategies of transmission control, according to different kinds of data. Meanwhile, the advantage of UDP in transmission speed is kept. The significance of improvement made in transmission protocol is demonstrated in experiment.
