於有線電視網路中管理多類型服務之物件模型

DOCSIS是一個好的接取網路解決方案與平台以提供不同類型的服務｡然而從一有線電視系統業者的角度來看,一項服務可能跨越相異的網路或管理界線｡由於管理位於不同網路其上的多類型服務非常複雜,使得網路管理員迫切期待能擁有一追蹤工具｡所以一物件模型得以承載相應於不同服務､網路､設備､服務品質參數集之不同物件應運而生,以達此一追蹤工具,且能滿足保證服務品質之基本要求｡於本論文中,我們提出一物件模型以達成需求｡我們在模型中首先應用物件導向設計理念,如類別與繼承關係,並於實例中討論一些一般類別中的不同特例｡基於所提出之模型,稱之為DMSOM物件模型,所連接之服務品質參數集合會呈現在層狀結構的下方,並得以依服務及依網路元件為基礎,用來清楚地驗證服務品質｡再者我們將展現物件資料庫的實作｡我們亦將展現此一物件模型之附加價值 — 路由探索能力與所管理網路之網路連線清單資料庫,包含其實體連線｡最後我們將提出一套完整的程序來說明如何於實際網路市場操作此一物件模型以達到網路管理的目標｡

DOCSIS is a good access network solution and platform for provisioning multiple services. However, from cable operators’ point of view, a provisioned service may traverse the heterogeneous networks or administrative boundaries. The complexity of managing these multiple-service overlaying on multiple-network makes it more desirable for network administrators to have a general pursuing tool. Therefore, an object model that is capable of accommodating various objects corresponding to diverse services, networks, equipments, and Quality-of-Service (QoS) parameter sets is required to achieve the pursuing tool, and is also essential to guarantee the service quality. In this thesis, we propose an object model aiming at meeting these requirements. Object-oriented design concepts like classification and inheritance relationships are first employed in the generic model, and then various specializations of the generic classes are discussed along with practical service examples. Based on the proposed model, called the DMSOM model, the associated QoS parameter sets will be represented in the bottom of hierarchical architecture, and help to validate the service quality explicitly on a per-service and per network element basis. Next we will present the implementation of object database. We will also show the added value of the object model – the route discovery capability and the inventory database of the managed network, including its physical link. Finally we will present a framework how to operate the object model in the field to achieve the goal of network management.
