【正文】 abstract II 寬帶接入網(wǎng)設(shè)計(jì)方案研究與分析論文 摘要 電信網(wǎng)發(fā)展到今天，正在進(jìn)入一個(gè)新的轉(zhuǎn)折點(diǎn)，呈現(xiàn)出寬帶化、 IP 化及業(yè)務(wù)融合化的趨勢。電信網(wǎng)寬帶化首當(dāng)其沖的就是接入網(wǎng)的寬帶化。近幾年，為了適應(yīng)新時(shí)期下社會(huì)發(fā)展的需求 ,并且滿足人們?cè)谏钪信c工作中對(duì)網(wǎng)絡(luò)的要求，接入網(wǎng)的寬帶化加快了步伐，正在向著多樣化的方向發(fā)展，涌現(xiàn)出各種各樣的寬帶接入技術(shù) ,這些寬帶接入技術(shù)各自有著自身的一些特點(diǎn) ,在選擇的時(shí)候應(yīng)該結(jié)合實(shí)際的需要來進(jìn)行選擇?，F(xiàn)對(duì)寬帶接入網(wǎng)進(jìn)行了探討。 本文首先敘述了接入網(wǎng)的基本概念，然后介紹了主流寬帶接入技術(shù)，接著著重描述了 ADSL 的可行性分析及其接入網(wǎng)的網(wǎng)絡(luò)設(shè)計(jì)，并對(duì)它進(jìn)行性能分析，提出改進(jìn)方式。 關(guān)鍵詞 ：接入網(wǎng)，發(fā)展， ADSL abstract IV Abstract The telemunication work development to today, is entering a new turning point, showing a broadband, IP and business integration trend. Tele broadband work is be the first to bear the brunt of the broadband access work. In recent years, in order to meet the needs of social development in the new period, and meet the requirements of work in life and work, and broadband access work to speed up the pace, is developing towards the direction of diversification, the emergence of a variety of broadband access technology, the wide band access technology have their own some characteristics the, in the choice of when should be bined with the actual to choose. The broadband access work is discussed. This paper describes the basic concept of access work, then introduces the main broadband access technology, and then focuses on the work design feasibility analysis and access work ADSL, and its performance analysis, put forward the improvement way. Keywords:Access work, development, ADSL 1 目 錄 摘要 ................................................................................................................................
