Design And Implementation Of Dongying Tobacco Companies Instant Communication System

Today’s social science and technology is developing rapidly, the rise of mobileinternet high-speed access and mobile phone application for development of adiversified, instant communication network applications are high-speed development ofthe situation. Through instant communications platform (Instant Messageing IM short)interaction is a network for the exchange of information of the main instant messagingapplications in such a large user base, the communication is the most basic human needs,and in fact from people inside the business Instant Messaging is also a measure of abusiness information, building of bad conditions.Designs an immediate communication system to need very many programmingability and the knowledge.This system development needs to experience the systemanalysis, the system design, realizes as well as tests four stages.This system uses the C/Sarchitecture, uses for to realize the cross platform immediate communication system,the database uses in the service end uses MySQL to use SQLite in the client side, thedevelopment integration environment uses Qt Creator, finally realizes based on the QtC/S structure cross platform immediate communication system. The key technologiesincludes: The concurrent processing technology, visits concurrently in the massiveclient sides; The rich text technology, plans with similar HTML such (in the similarHTML mark) to divide the different element with the special string, achieves theabundant and elegant effect by this; The data encryption technology, plans with AES theencryption algorithm CBC pattern to carry on the encryption to the information.Alsoguaranteed the encryption algorithm enough is formidable, the encryption speed isquick, and may counter calculate; The video frequency chats the technology, thegathering video frequency uses OpenCV, under the different platform can by the sameway convenient gathering camera data.The P2P file transfer technology, plans withUDP.This article studies the dongying tobacco companies internal instantcommunication system. Aimed at dongying tobacco company internal environment anduse requirements to develop high efficiency, stability, security, are excellentcross-platform, easier for secondary development of IM.
