The Design And Implementation Of Computer Network Management System In Guangdong Department Of CAPF

With the advance of computer network technology and the popularization of information system constructions in militaries, computer network is greatly developed and widely used in Guangdong department of CAPF (GCPF). Meanwhile, quite a lot new issues come forth in network management, especially in applications of network-based on-duty inspections. The network management is of the primary importance as the inspection is directly effected by the network status. The functions of network management system include: monitoring network performance, configuration parameter, alarms displaying and fault treatment, etc. And it could improve network security and efficiency. Therefore, the design and implementation of a network management system for the GCPF is of great importance to improve network performance.Based on in-depth analysis and comparisons of international and native network management systems, and taking the characteristics of GCPF network into consideration, a multi-layer distributed network management system for GCPF is designed and implemented using the NetInsight Pro platform, in which the SNMP protocol is adopted. The main advantages of the system are:1,The GCPF network is dispersed in multiple layers of large area, and independent in management. Therefore, a multi-layer distributed management system is used, which could effectively solve problems in multi-layer network managements.2,Considering the fewer species and small scale of network devices, SNMP and ICMP (ping) protocol are used to develop the algorithm for automatic topology discovery of networks, which can improves the finding accuracy.3,Configurable loop query intervals and the way the data transmitted between different layers are used to decrease the bandwidth occupancy of the network management system, which could improve the efficiency of network management system.4,To guarantee the network security and diminish the effect of environment, IP address bound monitoring technology is used to automatically prevent the connection of illegal device and dial-up internet connection. Therefore, the shortages of management through human beings are resolved.At the end of this paper, test results and its analysis are presented.
