Achieved Based On The Ip Protocol Network Polling

When internet is coming, the distance between people in different regions is no longer remote. For a network in managing, maintain a monitor system is necessary. That is, the server can monitor the running status of the clients, if necessary, can add some control function. This subject besides realizes the monitor function based on the polling principle, based on monitor function add the services of immediate correspondence between server and client and file transfer(The server provides the function of upload files and download files for clients), the server can also maintain running log. The design of this software system based on these principles: high efficiency, uses small memory, practical and high independence. The subject has a very wide range, it mainly involves the TCP/IP protocol and its programming interface, the design of server in network service, development under the Win32 platform, and the data file system's design, the use of MFC construction, the multi-thread development and so on. In the network service programming, the efficiency is a very crucial question, so in the development, I often set strict requirements to upgrade the running efficiency and reduce the use of memory, try my best to make the use of memory and the running efficiency achieves the best combination.This subject studied network polling implement based on IP protocol, through this research results we can do the second development to meet the needs of different users, such as: the development of network monitoring and controlling, the development of network hackers software, the development of immediate correspondence software and so on.
