An Ethernet device and Ethernet affair processing method based on the SDH, the device includes Ethernet affair processing unit, synchronous digital hierarchy cluster-Road processing unit, cross-connect processing unit; Ethernet affair processing unit performs the physical layer processing and MAC layer processing for the received 10G Ethernet affair data, and after performs the encoding and virtual containers mapping for the data which has been processed, outputs it; synchronous digital hierarchy cluster-Road processing unit through the cross-connect processing unit to receive Ethernet affair processing unit output of 10G Ethernet services to the SDH mapping the data ,and performs the overlap segment spending process and the renewable segment spending process for the data, then sends it to the synchronous digital hierarchy network. The device and method make the 10G Ethernet affair encode and decode at 64b/66b part of the package, such as GFP coding replaced, so that the EOS equipment will be more flexible, 10G Ethernet access will be more efficient, and smaller delay. |
