Design And Implementation Of Resource Management System For The Transmission Net Of Shuohuang Railway Company

The transmission system which is represented by optical fiber communication is the fundamentals network of modern telecommunication.Naturally the management of the transmission system become the most important part of Network Management.As the capacity,complexity,diversity of telecommunication network increases,the management of transmission system confronts challenges as well.It's easy to see,that the traditional way of network management provided by Vendors could no longer keep up,both in capacity and in rate.Take a look at the Network Management for Shuohuang railway company(SHNMS).There are already 3 transmission systems equipped in the Shuohuang Railway Telecommunication Network(Huawei,Zhongxing,and Alcatel). Each has its own(NMS) Network Management System.These Isolated NMS from Vendor has the following defects:First,Each NMS is different in GUIs and its operating guidelines.Second,these NMS supplied by Vendors are isolated,and only care for equipments in theirs own scopes,which make collective network management hard.Apparently,Integrated Network Management System(INMS),rather than isolated NMS are needed to implement monitoring the network from a higher perspective.To achieve this,we studied SDH,made detailed introduction about the ideas of important resources like slot,ne,and reviewed the procedures of multiplexing in SDH. We also made concise description about several key technologies used in NMS: Network interfaces,JAVA Swing JMS.SHNM,which is the background of Resource Management of transmission system,is introduced brieflyThe network interface acts as resource information collector and adaptor.We described its idea,place and gave the design of 2 main software functions. While building the information model of resources in transmission systems,both their basic attributes and interrelationships are emphasized.We divided the resources in transmission systems into 3 parts,the physical resources,the logic resources,the space resources.We then achieved their information models one after another.At last gave a simple database design focusing on the interrelationships of the different kind of resources.We also designed the software modules the resource management system, Including public configuration of physical equipment,the equipment panel,and the location of related resource.Detailed introductions about the configuration of path and circuit are given,especially the procedures to create them.Finally,demonstration of the system is presented.
