Here , the managed objects are classified into four types : m - based ( storing all resource information in memory ) , md - based ( storing the base managed object in memory and the list of attribute in persistent storage ) , mr - based ( storing the base managed object in memory and accessing the resource directly ) and d - based ( storing all resource information in a database ) . to achieve those , a generic class is designed for the need of the basic managed object ; as a result , the managed object class abstracted from the managed objects mentioned above can be derived from this generic class when corresponding attributes and methods are added . finally , a mib storage structure of a real application inherited from its super classes can be constructed 該實現(xiàn)方法首先根據(jù)管理系統(tǒng)中被管對象的特點將其分為基于內(nèi)存( m - based ) ,基于內(nèi)存?數(shù)據(jù)庫( md - based ) ,基于內(nèi)存?指針( mr - based )和基于數(shù)據(jù)庫( d - based )等四種類型;其次,定義被管對象基類用于描述通用的被管對象,然后以此基類為基礎,繼承并添加與具體模式有關(guān)的數(shù)據(jù)成員和方法成員,實現(xiàn)其它類型的被管對象類;對于具體的網(wǎng)管應用,則根據(jù)具體要實現(xiàn)的被管對象特點,從合適的被管對象類衍生,添加與具體應用有關(guān)的代碼,即可實現(xiàn)相應的mib存儲結(jié)構(gòu)。
This paper addresses how to introduce the corba techologies into the tmn , meanwhile , it also addresses the possible applicatioin of corba in tmn . finally , this paper also introduces the detail design of how to apply a corba middleware tao into alcatel ' s forth generatioin project , using corba as the network management interface between the qaf and nef , the functions in tmn . this paper especially pays attention to the detail design of the netowrk management ' s softweare framework , managed object class and notifciation management , try to find a more elegant design pattern in network management development 隨著電信網(wǎng)絡技術(shù)的不斷發(fā)展,各種新業(yè)務的日新月異,傳統(tǒng)的基于osi協(xié)議棧的電信管理網(wǎng)tmn在開放性,分布式,互操作性和實現(xiàn)的復雜程度上都日漸不能滿足需求,為了解決這樣的問題,國際電信聯(lián)盟itu - t將corba技術(shù)引入電信管理網(wǎng)中,本文就如何在tmn電信管理網(wǎng)中引入corba技術(shù),引入后的實際設計問題,以及corba技術(shù)在tmn中可能的應用做了一定程度的探討,并結(jié)合alcatel4g網(wǎng)管子項目介紹了如何將基于corba的中間件tao ,應用在網(wǎng)元層網(wǎng)管系統(tǒng)中,作為q接口適配層qaf和網(wǎng)元功能層nef的標準管理接口。
