A method for cyclic code encoding includes: generating, based on a first symbol sequence related to a first part of symbols in the K payload symbols, a first parity sequence corresponding to the first symbol sequence; generating, based on a second symbol sequence related to a second part of symbols in the K payload symbols, a second parity sequence corresponding to the second symbol sequence, where the first part of symbols are different from the second part of symbols; and generating the (N−K) parity symbols based on the first parity sequence and the second parity sequence.

Method and chip for cyclic code encoding, circuit component, and electronic device

Embodiments of this application disclose a synchronization method and a device. A device marks, based on a preset period, a periodic code block in a data bitstream to be sent from a MAC layer to a PHY layer. The device sends the data bitstream to a peer device through the PHY layer, records a sending time of each periodic code block as a first timestamp during sending, and returns the first timestamp to the MAC layer. By marking a timestamp for the periodic code block received from the MAC layer, the device sets a PHY-layer-based time reference scale (namely, the first timestamp) at the PHY layer.

Synchronization method and device

A method includes: sending, by a first device, a first bit stream to a second device, where the first bit stream is sent over N logical lanes of a physical layer of the first device; sending, by the first device, a first trigger marker group to the second device, where the first trigger marker group is used to indicate that the sending of the first bit stream ends; and sending, by the first device, a second bit stream to the second device in response to the sending of the first trigger marker group, where the second bit stream is sent over P logical lanes of the physical layer of the first device, and both N and P are positive integers.

Ethernet data transmission method and communications device

A flexible Ethernet (FlexE) frame forwarding method, including receiving a first frame through a FlexE client input channel, obtaining a first channel identifier used to indicate the FlexE client input channel and a first subchannel identifier carried in the first frame, where the first subchannel identifier is used to indicate a logical subchannel of the FlexE client input channel, searching a preset forwarding table based on the first channel identifier and the first subchannel identifier to obtain a second channel identifier and a second subchannel identifier, where the second channel identifier is used to indicate a FlexE client output channel, and the second subchannel identifier is used to indicate a logical subchannel of the FlexE client output channel, and forwarding the first frame based on the second channel identifier and the second subchannel identifier.
