使用方法： 首先安装winpacp驱动，发送的时候可以选择ARP的TYPE。如果是ARP请求报文，则只要输入要问的IP地址，如果是ARP应答报文则要输入发送端的IP以及对方询问MAC地址对应的IP地址。 最后的发送速度可选参数为：（大小写敏感） fast----------最快 hear---------每60MS一个包（比较适合结合SNIFFER做监听） slowhear---每500MS一个包 auto---------每1秒一个包 slow---------每2秒个包 -Usage: First, install the driver winpacp, send when ARP can choose the TYPE. If the ARP request message, the question as long as the input to the IP address, if the ARP response packet will have to enter the sending end of the IP and MAC address of the other asked whether the corresponding IP address. The final optional parameter for sending speed: (case sensitive) fast fastest hear- a packet every 60ms (SNIFFER make more suitable combination of monitor) slowhear- every 500ms a packet auto- every one seconds a packet slow- every two seconds of packet

开发语言可以为C#,Delphi和VC，并支持面向对象的开发的支持，在服务容量增加的时候很方便的扩充，因此可以很方便的开发C/S网络应用。此外，充分利用UDP的优点并增加了通讯的可靠性。以及对用户的可管理性简化了用户的开发难度。-Development language for the C#, Delphi and VC, and to support the development of object-oriented support to increase capacity in the service when the expansion is convenient, it can be very convenient to develop C/S network application. In addition, full use of the advantages of UDP and increased communications reliability. As well as the users can simplify the management of the development of user difficulty.

UDP MFC 包含服务器和客户端，  本实验设计内容是：设计一个程序，实现聊天功能，要求有客户端和服务器端。客户端能实现消息的输入和发送、接收消息、连接服务器与断开连接等基本功能；服务器端要求能收发信息、保存客户端的IP信息地址、将接收到的消息向所有客户端转发等基本信息。
