Design and Implementation IP Messenger Based on LAN
Abstract
The network communication already do not calculate the new things now, but the majority network communication all need to be support by the server on the Internet, this make these user have the large-scale internal network who many problems, such as waste network resources, be attacked by network, dissemination virus, destruction defense system and so on. Because the interconnection network communication facilities on the interior communication brought inconveniently for the enterprise, in order to facilitate internal communication between network user's, needs to develop one based on the local of instant message area network information receiving and dispatching system instant message facilities, realizes carries on the information which network the exchange. This topic design mainly aims at the local area network communication to develop the design, uses is the C/S skeleton,like IP Messenger, for chat and files transmission.
LAN against the text chat, documents and folders transmission, the design of a fake IP Messenger of LAN software, and analyze it in their areas of advantage. The design is developed by C program it can make in the cnvironment of windows 2000/net/xp of topic selection, in the environment The design altogether divides into five big modules, respectively is: First, introduction selected topic background and significance and domestic and foreign research present situation; Second, introduces the TCP/IP point to point protocol technology; C/S construction technique and sockt network programming technology; Third, carries on the demand of the current local area network file transfer to analyze and propose the solution; Fourth, carries on the design according to the solution to the system; Fifth, statistic the work plan, awalys and test the system and obtains the testnesult.
