摘要:

为了很好地满足战术训练模拟器对网络数据实时性和可靠性的要求，提出AUDP(Augme nted UDP)模型。该模型在程序的应用层，通过增加用于可靠传输的协议头，采用智能重发机制、大数据包智能分包重组机制、多线程数据处理机制，实现了数据高效可靠地传输。同时，从原理和实验数据详细比较了AUDP与TCP和普通UDP方法之间的差别，分析了各自的优缺点。实验数据表明，传输小于50 kbyte时，AUDP的效率要高于TCP约20%；而在一次性传输的数据大于3 Mbyte时，TCP的效率要高。结果说明AUDP比较适合战术训练模拟器网络通信需要。

Abstract:

For the reliable and realtime data interchanging of tactical training simulators, a new AUDP model (Augmented UDP) is proposed. It adds a new protoco l in the application layer for reliable data transmission on UDP, and presents t he software architecture which uses the mechanism of autosending unconfirmed d a ta packets, dividing and reassembling large message automatically, and arranging huge data blocks with multithread, to realize reliable high capacity communic a tion.The advantages and disadvantages of AU DP, TCP and UDP are analysed.Experiment results show that AUDP is faster than TC P about 20% while working with normal commands whose sizes are less than fifty t housand bytes. But TCP is better for large commands whose sizes are more than 3M byte. It demonstrates AUDP is more effective for tactical training simulators  communication.
