附表 國外品牌2003年中國市場銷售統(tǒng)計(jì)表

摘要：ptn（分組傳送網(wǎng)，packet transport network）是指這樣一種光傳送網(wǎng)絡(luò)架構(gòu)和具體技術(shù)：在ip業(yè)務(wù)和底層光傳輸媒質(zhì)之間設(shè)置了一個(gè)層面，它針對分組業(yè)務(wù)流量的突發(fā)性和統(tǒng)計(jì)復(fù)用傳送的要求而設(shè)計(jì)，以分組業(yè)務(wù)為核心并支持多業(yè)務(wù)提供，具有更低的總體使用成本，同時(shí)秉承光傳輸?shù)膫鹘y(tǒng)優(yōu)勢，包括高可用性和可靠性、高效的帶寬管理機(jī)制和流量工程、便捷的oam和網(wǎng)管、可擴(kuò)展、較高的安全性等。

關(guān)鍵詞：ptn ；sdh mstp； 優(yōu)點(diǎn) ;原理； 應(yīng)用

中圖分類號：tn915 文獻(xiàn)標(biāo)識碼：a

從傳送網(wǎng)的發(fā)展過程來看大致經(jīng)歷了pdh（準(zhǔn)同步數(shù)字體系）、sdh（同步數(shù)字體系）、wdm(波分復(fù)用)、mstp（基于sdh 的多業(yè)務(wù)傳送平臺）、ptn（分組傳送網(wǎng)）五個(gè)發(fā)展階段。

在以往的電信網(wǎng)中，多使用pdh設(shè)備。這種體系對傳統(tǒng)的點(diǎn)到點(diǎn)通信有較好的適應(yīng)性。而隨著數(shù)字通信的迅速發(fā)展，點(diǎn)到點(diǎn)的直接傳輸越來越少，而大部分?jǐn)?shù)字傳輸都要經(jīng)過轉(zhuǎn)接，因而pdh系列便不能適合現(xiàn)代電信業(yè)務(wù)開發(fā)的需要，以及現(xiàn)代化電信網(wǎng)管理的需要。sdh就是適應(yīng)這種新的需要而出現(xiàn)的傳輸體系。

sdh-容量較大，一般是16e1到4032e1。sdh是一種將復(fù)接、線路傳輸及交換功能融為一體、并由統(tǒng)一網(wǎng)管系統(tǒng)操作的綜合信息傳送網(wǎng)絡(luò)，它可實(shí)現(xiàn)網(wǎng)絡(luò)有效管理、實(shí)時(shí)業(yè)務(wù)監(jiān)控、-絡(luò)維護(hù)、不同廠商設(shè)備間的互通等多項(xiàng)功能，能大大提高網(wǎng)絡(luò)資源利用率、降低管理及維護(hù)費(fèi)用、實(shí)現(xiàn)靈活可靠和高效的網(wǎng)絡(luò)運(yùn)行與維護(hù)。
