万兆以太网技术

10GB Ethernet's Technology

近年来,高速以太网技术已经超越传统的局域网范畴,越来越多地被应用于各种Internet接入网络骨干,成为推动Internet网络快速发展的技术主流。目前,以太网骨干技术已经进入万兆时代。对万兆以太网数据链路层进行了介绍,包括相关物理媒介层、广域网物理接口、SDH接入、WDM接入,以及万兆位以太网速率的QoS。

In recent years, the high speed Ethernet technology already has surmounted the category of traditional local area network, and more and more has been applied to various Internet network backbone, becoming the technical mainstream of the fast development Internet network. At present, the Ethernet backbone technology has already entered into the age of 10Gb. This article presents 10Gb Ethernet Datalilak layers, including the correlation physics medium level （P M D）, the WAN physics connection, S D H access, W D M access, as well as 10GB Ethernet＇s QoS.
