The Socket Programming and Software Design for Communication Based on Client/Server

This paper introduces the application of the client/server(C/S) mode, the concept and the programming principle of the socket based on C/S. The method of software design for the communication between the client, server-process using the socket mechanism is mainly analyzed, and gives examples of connection-oriented service program. The transmission layer can provide connection oriented to use TCP protocol, connectionless-oriented to use UDP protocol. There are two different kinds of services with different kinds of sockets. Only by understanding the characters of TCP protocol and UDP protocol, the service provided by the two protocols for application, can we know what deal with in these protocols, what need to deal with in application, can we easier compile vigorously and healthily, highly efficient client service program.
