     One is the application of T/TCP protocol that is known by few people. T/TCP protocol is the attached one of TCP and has been defined in the standard RFC 1644 in 1994. T/TCP is a middle course, which can not only speed up the transaction of short length data but also can preserve the nature, stability, reliability and non- repetition of TCP protocol.
     针对这一出发点,作者提出了两种解决方法,一种是传输层采用罕有人知的T/TCP协议,该协议是TCP/IP协议的补充协议,1994年就以RFC1644标准定义,这是一种对小量数据加速交互的进程而又保留了TCP稳定、可靠、无重复传输的择中方案;

According to Similar FT3frame format and its checkout mode of DNP Data Link Layer,the relationship between FER(Frame Error Rate)and BER(Bit Error Rate),frame length is deduced.In addition,the computation formulas of average transmission times and repeat transmission times guaranteeing the correct transmission of telecontrol information are given.Based on the computation formulas and the real time performance demand of information transmission,the real time perfor-mance of three transmission modes is analyzed.The design considerations and optimization means of three modes are proposed according to their transport characters.In polling mode,the selection way and extension of polling interval of master polling outstation are illustrated in order to ensure the real time performance of Class1data.In cyclic data transition mode,the feasibility and necessity of outstation repeatedly transferring important information three times is discussed in giving atten-tion to reliability and validity of information transmission,and the choice range of optimized repeat transmission times is confirmed.In un solicited response mode,the constraint relationship between transmission velocity and BER is presented in the case of station configuration.
