Design and implementation of chat room based on UDP

Abstract

As a common technology used in modern computer network communication, Socket network programming is one of the most popular technology to develop based on TCP/IP because it can customize packets communicate with each other effectively [1]. Network communication uses the interface which provided by operating system at different levels of communication to implement the secure communication in the process of network. Socket communication belongs to the bottom level of network communication, and API is used to program for network communication. This paper provides a method about a chat room using socket based on UDP (User Datagram Protocol). This design includes two parts, Server and Client. After client and server set up to connect, you can achieve many machines to communicate. It is equivalent to a dedicated chat server, a simplified WWW server. This system designed with C++ achieves a satisfying effect by experimental verification. © 2009 Springer Berlin Heidelberg.
