Research And Application Of Xi’an Railway Communication Integrated Network Management System

With the high speed development of China Railway, the railway communication network and equipments increased in a great deal, and distributed more widely.It is important to establish an efficient and comprehensive railway communication network management system, but the current situation of the railway communication network is:the complicated network environment and variety network protocol along with the increase of network nodes and the expand of kinds reflect the limitations of devices network management system. Thus produced the railway communication integrated network management.The railway communication integrated network management system is not a simple repetition with the equipment network management system witch adopts a series of communication protocols (such as Socket) to exchange data through its northward intefaces, then integrate network management system filters and abstracts the data that equipment network management system provides through its northward interfaces, so the integrated network management system can master the entire network in the overall situation.The integrated network management system mainly consists of two tasks:one is to monitor the running state of the network, the second is to control the operation of the network state. we can found bottlenecks and crisis in real network environment by monitoring the running state, and we can ensure the normal operation of nodes efficiently through controlling and regulating network node status. The railway communication integrated network management system makes the network resource allocation optimization, reliable and effective based on network monitoring and controlling.However the diversity of model and no unity of architecture make the railway communication integrated network management system lacking of an effective mechanism and the standard model when the integrate network management to manage the network. According to the above problems, this thesis deeply study the model of Xi’an railway communication integrated network management system in the application layer and establish one kind of effective management model and make the model to use in actual projects. The system use "More better services for railway communication" as the center to change the management from network-oriented to use-oriented. The system can master the entire network timely by combinating the railway communication and integrated network management.This thesis analysis the factors detailedly such as the demand of the Xi’an railway communication integrated network management system and studies the model architecture in-depth and the detailed designning and implementation of the system. Starting from the overall requirements of the system, it makes the solution based on the distributed environment of the system combining the analytical framework technology and communication technology.Main research contents are as follows:1.This thesis provides a new type of efficient model for the system witch is suitable for general railway communication integrated network management system;2. This thesis analysis and designs each layer in the system model;3. This thesis achieves the system and tests it to evaluate evaluation theory and practice of the system.
