本文主要介紹了如何開發(fā)基于TCP/IP 協(xié)議網(wǎng)絡(luò)編程的自定義通訊協(xié)議，在QNX，Linux 和Windows 三種不同的操作系統(tǒng)平臺(tái)下實(shí)現(xiàn)多節(jié)點(diǎn)間的互相通訊。測(cè)試結(jié)果表明，該協(xié)議可以方便高效地實(shí)現(xiàn)多平臺(tái)下控制節(jié)點(diǎn)間的相互通訊，并且在長(zhǎng)時(shí)間、高頻率的通訊過程中，具有良好的實(shí)時(shí)性和可靠性。

Study and development of the User Defined Protocol Based on TCP/IP Jiang Min1,2 Shan Jiangfang1 Kong Jun2 1（Institute of Plasma Physics, Chinese Academy of Sciences, Hefei Anhui, 230031） 2（Southern Yangtze University, Wuxi Jiangsu, 214125） [Abstract]This paper mainly presents how to communicate between QNX，Linux and Windows with a user-defined protocol based on TCP/IP protocol. Some results of the experiment are gained to show that it is quite easy to construct a rapid and stable communication with long time and high frequency between different operating
systems .
