摘要
在SDH网络上传送以太网业务 (EOS)具有巨大的优势。EOS能利用现有的SDH网络为以太网业务传送提供完善的OAM性能。在EOS系统中 ,透明传输以太网业务有非常重要的作用。详细分析了时钟、故障传递、流量控制和自协商相关的透明传输问题 ,相应的解决方案也同时提出。
There is considerable interest in using Ethernet ove r SDH(EOS) for Ethernet transport in a wide area network. EOS leverages the existi ng SDH infrastructure to provide efficient Ethernet transport with excellent OAM capabilities. Transparent transport of Ethernet information plays an important role in the deployment of EOS. Some issues such as clock, fault propagation, flo w control and auto-negotiation are analyzed in detail and solutions to the prob lems are also presented.
