【摘要】 以光纤通信为代表的传输网构架了现代通信最重要的基础网络,为各类电信业务网提供传输通道和传输通道保护。对传输网进行管理自然是整个网络管理系统的重要组成部分。随着电信网络规模的日益扩大,网络的复杂性和异构性越来越强,传输网网络管理也面临着新的挑战。依靠那种传统的、由单个厂商提供的网元层管理系统(EMS)来管理传输网络,在容量和效率上已难以适应目前的变化。例如朔黄铁路通信网,就已装备了华为传输、中兴传输、阿尔卡特传输三套传输系统,三套厂商的网管系统孤立分散运行:一方面,不同厂商的网管系统有不同的操作界面,维护人员需要大量的时间和精力分别熟悉这些网管系统;另一方面,不同厂商的网管系统互相独立,各自管理各自设备,这为全网统一管理和调度增加了难度。为解决上述问题,我们迫切需要一种传输网综合网络管理系统实现来对不同厂家子网的宏观监测、集中管理。论文首先考察了传输网的主流技术同步数字体系(SDH),对时隙、网元、SDH复用步骤等与传输网资源管理直接相关的知识进行了重点介绍。对传输网网络管理设计开发中涉及的关键技术,如网管接口技术、Java Swing、JMS技术进行了简要描述,对作为传输网资源管理子系统设计背景而存在的朔黄铁路通信网综合网管系统进行了介绍。论文研究了传输网资源信息的采集配置接口,介绍了采集配置接口的概念、地位以及采集适配接口信息同步的设计实现。论文建立了传输网网络资源模型,结合传输网实际结构,从资源对象基本属性和资源对象相互关系两个角度,对传输网物理资源、逻辑资源、空间地理资源三大类资源分别进行资源对象建模,给出了数据库表关系。论文在资源建模的基础上,完成了传输网资源管理子系统各子功能模块的设计实现。主要包括:公共设备资源一般配置、设备面板查询、设备资源关联查询,重点介绍了对通道、电路等重要业务资源的配置,特别是通道创建和电路创建的流程。更多还原

【Abstract】 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.更多还原
