摘　　要：为实现局域网内多个终端间信息、文件互通,同时满足用户对数据传输的即时性需求,结合P2P、Socket等通信技术,设计了一个多线程即时通讯系统。系统实现了局域网络中用户登录、在线用户列表实时更新、即时性信息传输以及文件传输等功能。系统摒弃第三方集中服务器,有效提升了数据传输的安全性;同时,数据传输不需第三方中转,其传输速率可得到大幅提升。此外,系统采用多线程通信技术,进一步加速了大文件的传输速率。To achieve the message and file interchange among multiple clients, as well as the immediacy demand of data transmission of the clients in a local area network, a multi-thread real-time communicating system is designed using technologies such as peer-to-peer, socket and so on. The system realized the functions of user login, real-time updates of online user list, real-time message and file transmission, etc. The system eliminates the third-party centralized server, which effectively improves the security of data transmission;In the meanwhile, since there is no need for a third party to transfer data, the data transmission rate can be greatly increased. In addition, the system uses multi-thread technology, which further accelerates the transmission rate of large files.
