Based On Itil Network Operation And Maintenance Management System Design And Realization

With the rapid development of e-government, local governments required a high performance and qualified information system to enhance the lead management and innovation, especially under the background to construct the service-driven government. But they met a lot of issues when setting up the platform internal, which was conflicted with a large quantity of applications, devices, unit types and device vendors. In general, a Chief Operating Officer requires high quality in reliability, accessability and security. So it is urgent to have such a dependable network operation and maintenance system in order to increase work efficiency and to guarantee the operating security of e-government. With a reference of successful experience oversea in ITIL (Information Technology Architecture Library) field, they made clear to develop a ITIL-based system to solve the current issue.Firstly, the essay discussed about the architecture and components. The system is divided into three parts, polling components, server components and console components. The polling part is to implement the collection of device data and monitor through various communication protocols. There are different functional polling components to gather the device status, to discover the network topology, to receive the trap data and to early warn by the threshold judgement. The server part is core. Its main function is to maintain the overall database, which stores data collected by the polling part so as to provide a console interface to operate. The data contains information in the aspects of network topology, configuration and event log. The console part runs on the work station. It is a graphical UI.Secondly, it mainly discussed the design and implement of the management of device, early warn and log in the console. Device management module includes the device's addition, classification, modification and deletion. Early warn module contains early warn data collection, storage, analysis and many kinds of presentations. There is sound, color, note and external program invoke. Log management module includes collection, classification, history and current log list.Finally, it argued the issue and solution in the process of the deployment and implement. It also made a comparison of various network management products in the market and look forward to the future's trend. To draw a conclusion, it is highly estimated to develop such a custom-made, extendible and continuable supported system.
