自復環電信網路模擬系統之設計與實作

Abstract

環電信網路是新一代的電信網路﹐具有高頻寬､高可靠度之特性﹐而在 架設自復環電 路之時﹐也應同時發展管理自復環電信網路的整合型網管 系統以便網路架設完成後 ﹐ 迅速作有效管理﹐本論文之目的即是設計與 實作一個自復環電信網路模擬系統，以作 路管理系統之測試平台。 文分 析自復環電信網路上各種網路元件之特性以及標準電信網路對於網路管理 所提供 援﹐找出欲模擬對象之特徵､提出模擬時的假設以及模擬系統之 功能需求﹐在 SUN RC Workstation + UNIX 平台以及 IBM Compatible 統。模擬系統之主要功能如下： 模擬電信網路上的各種網路元件支援網 路管理之功能 提供設定網路事件產生的界面 提供各種網路元件將事件 通報給網管系統之界面 提供網管系統下達操作命令以及接收操作回應之 界面 未來網管系統進行測試時﹐將架在模擬系統之上﹐接受各種網路事 件之通報並下達管 理操作命令及接收操作回應﹐來驗證網管系統之各項 功能。 The "Self-Healing Ring (SHR) Telecommunication Network" is the one of newgeneration telecommunication network that has the feature of high bandwidthand reliability. Along with the establishment of the SHR telecommunicationnetwork, an associated integrated network management system should also bedeveloped in order to do effective management. The goal of the thesis is todesign and implement a simulation system for SHR telecommunication networkas the test platform of the network management system. In this thesis, weanalyze the feature of each kind of network element and its supporting networkmanagement functions in the standard telecommunication network. The character-istics of the objects to simulated, the assumptions and the functionalrequirement of the simulation system are thus acquired. Then, we design andimplement the SHR telecommunication network simulation system on SUN SPARCWorkstation with UNIX and IBM Compatible PC with Windows 95, both of whichhave the communication function the TCP/IP Socket service. The main functionsof the implemented system include:(1) Simulate the network management functions supported by the various network elements.(2) Support the interface to generate the network events.(3) Support the interface to notify the network events to the network manageme system(4) Support the interface for the network management system to deliver the operations and to receive the operation responses. When the network management system is to be tested and be validated its functions, the simulation system will deliver the notification of the network events and the operation responses to the network management system, and receive the operations from it.
