【Abstract】 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.更多还原
