Title Design and Implementation of The Network Traffic Monitoring
Abstract
With the rapid development of Internet, network safety has become people’s concern. virus, vigorous attack, illegal visit and so on can easily affect the normal network performance. Various kinds of network defending technology have been comprehensively applied into the management system of network safety. Network traffic system is one of the effective measures to analysis network condition. From the angle of analyzing packet traffic, it can examine the safety violation and the abnormal performance of network by timely collecting and monitoring packets information.
By using the way of object-oriented, this design makes a needs analysis and ability designing based on the study of network packet collecting and TCP/IP theory. Under the environment of Visual C++6.0, this system adopts VC program technologies of Socket-Raw, Windows register and IpHelper API. On the basis of system analysis, it makes a deliberate analysis and test of plans and details to implement packets collecting, protocol analysis and traffic monitoring. So this meets our needs and makes a reference for managers to get to know the network conditions.
