摘　　要：目的研究基于ＴＣＰ／ＩＰ协议的ＤＩＳ实时通信，提高其实时性．方法通过分析ＤＩＳ特点，根据ＤＩＳ通信服务的要求，对标准ＴＣＰ／ＩＰ协议进行改进，提出ＱＴＣＰ协议．结果ＱＴＣＰ简化了ＴＣＰ协议，减少了不必要的协议开销，提高了协议效率，缩短了数据平均传输时间．结论通过对ＴＣＰ／ＩＰ协议的适当改进，使ＤＩＳ数据传输的实时性得到一定的改善．Aim To improve the real time performance of data transmission in a DIS based on TCP/IP Methods Characteristics of communication in DIS are analyzed Some improvements are made to the standard TCP/IP protocol according to the requirements of DIS communication service thus the QTCP is proposed Results QTCP,an improved protocol of standard TCP protocol,reduces some overhead of TCP unnecessary to DIS The protocol efficiency is enhanced and the real time performance of data transmission improved Conclusion Real time performance of data transmission in DIS is improved by making some necessary changes to standard TCP/IP
