Design and Realize Communication System Based on LAN of C/S Architecture

Researching for practical network communication technology, this paper designs a network communication system running under the C/S (client/server) mode. Based on the socket communication, the network communication part adopts TCP/IP protocol and UDP protocol. By the system, users in LAN could communicate with each other in real time, conveniently and safely, the function of sending instructions and transferring files between users can be realized.
