基于P2P技术的企业即时通信平台开发研究

将即时通信技术与企业信息管理系统相结合建立企业即时通信平台、网络虚拟社区,实现企业职工之间的信息同步,职工之间进行信息交互、沟通.采用基于P2P技术即时通信的客户/服务器架构,使用从MFC类中的Casync Socket类的派生类实现底层通讯,底层利用UDP数据报协议进行通讯.各个用户之间采用对等网络技术(点对点网络技术)进行通信,它让用户可以直接连接到其他用户的计算机,进行资源共享与交换.

Research on Implementing Instant Message Platform of Enterprises Based on P2P Technology

Based on technology of the IM and information management system of enterprises, IM platform and virtual community constructed for staff keep message instant and communicate in more direct way. The mold of a server of instant correspondence is the backstage database, C/S between the customer and server structure is adopted, what of each customer adoption is a technique of P2P to carry on the correspondence, and use the ADO technique realization to the operation and the management of the database. The system uses the class derived from CAsyncSocket class which belongs to MFC to carry out the ground floor communication, the ground floor makes use of the UDP data report protocol to carry on the communication, makes use of the P2P way and carry out the un-line instant communication for any staff who has logged in the server.
