The Design And Implementation Of The Net Resource Monitoring System For Enterprise Campus Based On SNMP

With the development of computer technology and internet technology,the informalization level of enterprise is higher and the network resources of enterprise campuses are more than before.Network devices has been widely used and play an important role in the production,operation,official business and management of enterprise.Therefore,to monitor and manage the network resources in the enterprise campuses efficiently and to keep the effective operation of enterprise network provide important foundation for enterprise to function continually.In this paper,we design and realize a set of network resources monitoring systems for enterprise campuses based on SNMP protocol.The proposed systems have the following advantages:first,they can monitor and supervise the internet resources of campuses efficiently;second,they can improve the use of network resources;third,they strengthen the management and maintaining of network devices;fourth,these systems normalize the behavior of users in enterprise;finally,the stability and reliability of the network in enterprise have been enhanced by using these systems.Meanwhile,the proposed systems add module in internet of things(IOT),which can improve the extent of information and is useful for enterprise to carry out "wisdom campuses" and "wisdom enterprise" with the aid of IOT.Firstly,this paper analyses the development background for the monitoring and management system of enterprise net resources briefly,summarizes the current conditions of the system,based on which the paper also analyses the requirement of the system,propose four operational function modules of MIB Query,SNMP Setting,Equipment Abnormity Warning and IOT Management,and supportive function modules of Authority Management,System Setting and Diary Management.Secondly,this paper describes the design principle and target of the system,and designs the technical structure based on SNMP,including the logical structure and physical structure.The paper also designs the function structure of the system and describes the general implement methods according to the four layers of user,SNMP manager,SNMP agent and net device.Thirdly,the paper designs the system in detail,describes the modeling of the system,including business module,static structure and dynamic structure,and divides the system into some functional modules according to the use cases.The paper also detailedly describes the work patterns of the modules and the communication methods between them.Fourth,the paper introduces the implementation of the system,including the general implementation project,tools and environment.On the basis of functional modules,the paper also introduces the particular implementation methods for functional modules,database,interface and 10 modules,and shows some interfaces of the system.The paper describes the white-box testing,black-box testing(function testing)and performance testing for the system and describes the testing procedures and results.Finally we conclude the experience when systems used in requirement analysis,design,realization and test.Then we sum up the conclusions of system development,analyze the disadvantages of the systems in practical application,and look into the future of the systems based on IOT and "wisdom campusus".In conclusion,this paper design and realize the network resources monitoring systems of enterprise based on the SNMP protocol and the requirement analysis of network resources monitoring work of enterprise.The proposed systems are tested and operated in this paper.
