Design And Implementation Of Shanghai Information Network Access Network Management System

With the improvement of communication technology, information technology, access network become an important platform for the technical support, a large number of network communication equipment, the operating system of each different, a variety of service agreement and the coexistence of many Internet users in the same network space, network scale expanding, increasing complexity. To establish a set of standard and efficient network management system, accurately find network operation in the process of failure, the cause of the problem, solving the problem of fault; Real-time monitoring network running status, understand the running performance of network equipment, improve the level of network maintenance and management, guarantee the operation of the system is safe and effective, has become a top priority in the electricity sector of the marshalling station network maintenance work. This topic comes from Shanghai cable NGB access project "Oriental cable NGB access network unified network management system" of a component, the project aimed at the actual situation of NGB access network, at the same time for the entire NGB access network to realize "can tube, controllable and credible" target, put forward a set of perfect unity of NGB access network management system solutions. Contents include:equipment management, business management, and content management. NGB access part unified network management system:system of universal coverage TMN FCAPS network management system is put forward by the five functional domains, implement unified management of all NGB access network equipment.Based on analyzing the current situation of Oriental NGB access cable network, combined with Oriental cable NGB access network unified network pipe system construction goal and the localization, NGB access network unified network management system specific requirements include:centralized alarm management, performance management function and configuration/topology management functions, management system four aspects, and analyze the non-functional requirements. And then presents the overall design scheme of the network management system. Respectively from the design purpose, user characteristics, requirement analysis, system architecture, module partition, business processing and database design from several aspects. Last four key modules of the system:data acquisition module, performance management module, fault management module, a topology discovery module design and implementation in detail.
