| In large network centralized monitoring, network administrators comparative headache problem is how to real-time understand not around network equipment status. Network centralized monitoring system can help network managers control network real-time state, however, with the rapid development of the computer network and the widespread application, today's network scale and the increasing structure is complicated, safety situation becomes increasingly serious, these factors are greatly increased the network monitor of difficulty.Network centralized monitoring system structure based on SNMP has simple, extensible characteristic, research network monitor system based on SNMP has important realistic significance. This article analysised SNMP and it's centralized monitoring model, introduce network centralized monitoring system's design and realize process based on SNMP. The main contents include:(1) Expounds he principle of SNMP and relevant knowledge, this is the basis for the development of the system and protocol standards that must be followed.(2) From analyzing the structure of network centralized monitoring software, analyzed and summarized the system's functional requirements and non-functional requirements.(3) Put forward the basic structure model of network centralized monitoring system based the feature of SNMP centralized monitoring model, according to the function, actual centralized monitoring system structure be layered for four layers layered framework, thus the system is divided into four function module, and in each module realization methods for design.(4) Through the system function performance test and analysis verify the realization of the function.To a provincial Highway Administration analysis of network monitoring system as an example application of the system.(5) Through this summary and the outlook for future research work, and summarized the work of this paper and the main achievements and proposed future research directions. |
