Optical Network Element Layer Network Management Server-side Principle And Realization

Telecommunication network management is a series of monitor, upkeep and management operation to satisfy regular telecommunication network operation and the correct telecommunication business implementation. As the telecommunication fiber transmission network develops fast, new business ceaselessness increases by, the network scale expands unceasingly, equipment is more and more multiunit, net way diversifies also, tradition network management system already can not adapt to this large-scale network management, no matter on scale, on transferring efficiency or on system stability aspect. How to build a network management system to adapt to the current telecommunication network development is a important issue now.According to the problems in the current telecommunication network management system, the thesis, taking telecommunication network management system as main object of study, discusses the design of new comprehensive network management system and studies the design and realization of several modules at server deeply. The main content includes:1. First, the thesis introduces the concept of Telecommunication Management Network, analyzes the current network management system existence issue and the development tendency and discusses the current network management system existence issue. After that the function model of Telecommunication Management Network has been discussed simply.2. Then, the thesis studies the comprehensive network management system based on distributional middleware and the emphasis is the design of server. And it discusses the way of plug-in development, multi-processes session and common configuration which simplifies business flow.3. The south adapter framework has been designed and realized.4. The alarm module and resource module have been designed and realized.The comprehensive network management, adopting Common Object Request Broker Architecture distributed middleware effectively, enhances large-scale system stability and system transmission efficiency and supports multi-platform and distributed application. The plug-in management mechanism has enabled the system extensible easily. Realization of south adapter has supplied the unified way of protocol conversion and effective communication design to the system. Realization of the alarm and resource modules has finished the relevant business function on system.
