SDH是一種將復接、線路傳輸及交換功能融為一體、并由統(tǒng)一網管系統(tǒng)操作的綜合信息傳送網絡，是美國貝爾通信技術研究所提出來的同步光網絡（SONET）。國際電話電報咨詢**會（CCITT）（現(xiàn)ITU-T）于1988年接受了SONET 概念并重新命名為SDH，使其成為不僅適用于光纖也適用于微波和衛(wèi)星傳輸?shù)耐ㄓ眉夹g體制。它可實現(xiàn)網絡有效管理、實時業(yè)務監(jiān)控、動態(tài)網絡維護、不同廠商設備間的互通等多項功能，能**提高網絡資源利用率、降低管理及維護費用、實現(xiàn)靈活可靠和***的網絡運行與維護，因此是當今世界信息領域在傳輸技術方面的發(fā)展和應用的熱點，受到人們的***重視。

<p> 若此時C到A的路由是C→D→A，那么業(yè)務從A到C和業(yè)務從C到A的路由不同，稱為分離路由。 </p> <p> 我們稱一致路由的業(yè)務為雙向業(yè)務，分離路由的業(yè)務為單向業(yè)務。常見組網的業(yè)務方向和路由。 </p> <p>
