摘要： Methods, apparatuses and systems for transporting multi-lane Ethernet signal are disclosed. The method primarily includes utilizing a plurality of timeslot channels and justification bytes configured in the OPUk-Xv to build up multiple virtually concatenated transport lanes; and transporting a lane of independent Ethernet data via each lane in the multiple transport lanes. Such schema allows to transparently transport multi-lane Ethernet signal over OTN and addresses the uncontrollability of the time delay occurred when multi-lane Ethernet signal traverse over OTN. In addition, the problem that the frequency offset does not fit the IEEE definition of the Ethernet interface is solved.

摘要： The embodiments of the present disclosure provide a method, an apparatus, and a system for transmitting service data on an optical transport network. The method includes: mapping the service data into a low order flexible optical channel data unit (ODUflex); multiplexing multiple low order ODUflexs into a high order ODUflex; adding a forward error correction (FEC) overhead into the high order ODUflex to generate a flexible optical channel transport unit (OTUflex); and splitting the OTUflex into multiple data channel signals, and modulating the data channel signals to orthogonal frequency division multiplexing subcarriers to send the orthogonal frequency division multiplexing subcarriers. The foregoing solution provides OTUflexs. Therefore, the network adapts service data for flexibly variable line rates of the optical transport network through a control protocol, and transmits service data of different rates to meet the development requirements of higher-rate optical transport networks.
