Abstract: Embodiments of the present disclosure provide a data transmission method, which can meet a requirement for an Ethernet network with diversified rate levels. The method includes: grouping media access control (MAC) layer data into a plurality of MAC layer data groups; allocating, according to a bandwidth required by a target MAC layer data group and a reference bandwidth of a logical channel, at least one target logical channel to the target MAC layer data group; encoding the target MAC layer data group to generate target physical layer data, where the target logical channel corresponds to the target MAC layer data group and the target physical layer data; and sending the target physical layer data and first indication information, where the first indication information is used to indicate a relationship between the target physical layer data and the target logical channel.

Abstract: Embodiments of the present invention disclose a method for generic mapping procedure (GMP) mapping, which includes: first the information about a adjusted time slot to be occupied by a second GMP block container is carried in the GMP overhead of a first GMP block container; then, the size of the second GMP block container is adjusted in accordance with the inforamtion; eventually, a client signal is mapped into the adjusted second GMP block container adopting a GMP scheme. This GMP mapping method, when working with a corresponding demapping method, provides lossless mapping and demapping of client signals during the process of bandwidth adjusting.

Abstract: The embodiments of the present disclosure relate to the field of communications technologies, and disclose a lossless adjustment method of ODUflex channel bandwidth and ODUflex channel. The lossless adjustment method includes: respectively adjusting, according to bandwidth adjustment indication request information, a time slot occupied by an ODUflex frame in a higher order optical channel data unit at an egress side of each network node on an ODUflex channel; and adjusting, according to rate adjustment indication information, a transmission rate of the ODUflex frame of each network node on the ODUflex channel, to enable the transmission rate of each network node on the ODUflex channel to be unified.
