Research And Development Of A Distributed Network Monitoring System

As the rapid development of computer network, it has already become a popular computation environment. But at the same time, the problems were following the computer network unceasing development, in which all sorts of securities hidden danger also seriously threaten each unit, the staff or the student accesses to the net. The net management already caused personnel headache to various network stuff. Insensible management, the violence, the cults, and the pornography and other bad information and virus are bringing consequences beyond estimation to every unit. To research a new distributive network management supervisory system under this background has great practical value and social efficiency.After studying the system structure, function and the characteristics of present domestic network management supervisory system structure, this paper proposed one distribution network supervisory system design method in view of existence questions of the central network monitor and control system.The paper will analyze the overall frame of the distribution network supervisory system, and offer a detail illustration of the functional design, the module design and the flow design of this system. The system consists of 3 sub modules: Control Module, Configuration Module and Interface Agent Module .The data packet interception technology has been adopted to develop the DLL controller independently, which can be inserted into the system essence of the monitored machine. Through which data packet interception and function of network control have been achieved, meanwhile, reliability has been enhanced.The paper thoroughly studied the port technology, which has been successively applied to the controlling end procedure. In this way, communication speed and the movement stability of control end and the large capacity pitch point end have been promoted. Based on the research of the ADO database programming technology, the paper studies direct database programming through the API function whichCOM provides, which has solved the database operation problems caused by the control end and the disposition end. At the same time, visiting speed of database has been enhanced.Finally, under the local area network circumstances of Windows operating system, the computation distributed distribution network supervisory system has been established. Live operation has proved that the function of this system has achieved the anticipated goals as convenient manipulation and stable and reliable operation.
