本程序设计分为服务器应用程序及客户机应用程序部分，采用Socket套接字库网络编程。（UDP）和（TCP/IP）相结合的连接方式，及解决了数据传输的时效性又能保证数据在传输的过程中不会丢失。另外程序采用多个线程来避免程序阻塞-The program design is divided into a server application and the client part of the application, using Socket socket network programming library. (UDP) and the (TCP/IP) combination of connections, and solve the timeliness of data transmission but also ensures that the data will not be lost during transmission. Another program uses multiple threads to avoid blocking procedure
