    摘要: The present invention discloses a method and an apparatus for transporting an ultra-high-speed Ethernet service. The method includes: distributing an ultra-high-speed Ethernet service data flow into n virtual channels, where a rate of the ultra-high-speed Ethernet service data flow is higher than a rate of 100GE; synchronously adding a marker to data of each of the n virtual channels; mapping the data of the n virtual channels channel by channel; and framing and transmitting the data of the n virtual channels. The method adopts a channelized transport manner to transparently transport an ultra-high-speed Ethernet service, and implements mapping processing on the ultra-high-speed Ethernet service, so as to reduce its complexity to a level for processing a low-rate Ethernet service and reduce implementation difficulty.

    摘要: A method and an apparatus for transmission using an interface, and a device. The method includes: obtaining a byte block stream, where byte blocks in the byte block stream are of a predetermined byte length; mapping the byte block stream to corresponding timeslots, where each timeslot corresponds to one byte block; distributing the byte block stream mapped to the timeslots; processing the distributed byte block stream based on an interface type configured for a physical interface; and sending the processed byte block stream. In the embodiments, data is transmitted based on a byte block distribution mechanism, to support different interface types, and a coupling relationship between service adaptation and a physical layer is decoupled, so that evolution and extension of transmission interface types do not affect a service adaptation procedure, thereby simplifying a transmission system.
