摘　　要：UDP滑动窗口协议是一种适用于现代通信系统中板间通信的应用层协议,它采用滑动窗口技术来保证数据包无重复、无丢包地按序递交。文中论述了基于UDP的滑动窗口协议并给出了实现方法,通过测试分析,该协议有效地解决了TCP的高协议处理开销和UDP的低可靠性之间的矛盾,而CPU占用率比单独采用UDP只增加约3%。UDP sliding window protocol is an application layer protocol applied to cross-board communication in modem communication system. It uses the sliding window technology to ensure data packets transmitted in right sequence, avoid packet duplication and loss. This paper discusses the UDP sliding window protocol and its implementation. The testing results show that, this protocol solves the conflict between the high protocol processing overhead of TCP and the low reliability of UDP effectively, and that CPU utilization is only about 3% higher than that in UDP.
