结合ＴＣＰ通信和ＵＤＰ广播通信的优点，实现了在局域网内既灵活又可靠地进行通信的方法。该方法使用一个唯一的标识号ＩＤ来标识通信各方，使得ＩＰ地址对于用户透明，从而实现了通信程序与具体计算机的无关性；同时，通过在应用程序之间保留多条虚连接的方法，实现了可靠的广播通信。 Combined with the advantages of TCP communication and UDP broadcast communication, it realizes a flexible and reliable communication method in LAN. The method uses a unique identification number (ID) to identify the communication parties so that the IP address is transparent to the user, so that the communication program has nothing to do with the specific computer. At the same time, by reserving multiple virtual links between applications, Achieve a reliable broadcast communications.
