 摘   要
 即时通讯系统是目前Internet上最为流行的通讯方式，它最基本的功能就是通过计算机之间的文本数据的互换形式，实现思想的交流和沟通，它的优点是方便快捷，为人们的沟通创建了一种新型的、廉价的、快速的、简便的沟通方式。
 然而由于目前的企业，尤其是大型的企业，大都有自己的Internet网络，其大多的工作流或内部交流都可以通过内部的Internet完成。如果企业中员工都使用目前免费的几种即时通讯软件，则必须对这些使用进行严格的审计和管理，这无疑给IT部门的工作带来了一定的麻烦。
 所以我认为，有必要也有可能开发一款即时通信软件，首先面向企业内部使用，进而发展到公网应用，以期成为一个企业内部、企业与企业之间互相交流的平台。首先在即时通讯系统服务的内部拓扑中我采用客户/客户模型（P2P）。这种模型主要用于小型局域网内客户间的互相通讯.它的特点是:使用容易,各客户上的资源可直接共享,并且容易安装和维护,不需要专用的服务器。然后我选择Visual C++进行程序编程，因为Visual C++编程语言是一种可视化开发工具，可用于开发基于Wondows操作系统的32位应用程序。
 最后，通过对即时通讯系统的研究，了解了现今即时通信系统的发展脉络，同时也指出了即时通讯研究中等待解决的问题。

  Abstract
Instant messaging systems is the most popular means of communication, it is the most basic functions of text data between computers through the exchange of forms, to achieve the exchange of ideas and communication, it has the advantage of convenience for communication between people to create a new, cheap, fast, easy means of communication.
However, due to the existing enterprises, especially large enterprises and large have their own Internet networks, the majority of the workflow or internal communication within the Internet can be completed by. If the enterprise employees are now free to use several instant messaging software, you must use strictly to these audits and management, which will undoubtedly bring to the IT departments some trouble.
So I think there is a need also possible to develop a real-time communication software, the first for internal use, then to the public network applications, in order to become an enterprise, business to business exchange platform. First of all, instant messaging services in the internal topology I used the client / customer model (P2P). This model is mainly used for small-scale local area network communicate with each other among customers. Its features are: ease of use, customers can directly share the resources, and easy to install and maintain, does not require a dedicated server. Then I select the Visual C + + for programming, because the Visual C + + programming language is a visual development tool, can be used to develop 32-bit operating system based on Wondows applications.
Finally, research on instant messaging, instant messaging systems to understand the current context of development, but also pointed out the study to wait for instant messaging solution.
Keywords：Instant messaging、P2P、Visual C++
