摘要： A forwarding table generation method is provided. The method includes: determining, by a forwarding device, a first timeslot set, where the first timeslot set includes multiple timeslots during which the forwarding device sends, to a first device by using a first flexible Ethernet group, multiple encoded data blocks generated by a physical coding sublayer; determining, by the forwarding device, a second timeslot set, where the second timeslot set includes multiple timeslots during which the forwarding device receives, by using a second FlexE group, the multiple encoded data blocks sent by a second device; and generating, by the forwarding device, a forwarding table, where the forwarding table includes a mapping relationship between the second FlexE group and the multiple timeslots included in the second timeslot set, and between the first FlexE group and the multiple timeslots included in the first timeslot set.

摘要： A method includes: a first chip receives a first data stream from a second chip, where the first data stream is obtained through encoding by using a first forward error correction (FEC) code type; and the first chip re-encodes the first data stream at least once, to obtain a second data stream, where the second data stream is a concatenated FEC code stream obtained through encoding by using at least the first FEC code type and a second FEC code type. This application provides a concatenated coding scheme, so that a gain is higher, an FEC code type conversion process is simplified, a delay and device power consumption that are required during FEC code type conversion are reduced, and a data transmission distance and a data transmission rate are increased.

摘要： This application provides an encoding method, comprising: encoding first data to generate a first encoded sequence; encoding second data to generate a second encoded sequence, where a quantity of bits comprised in the first data is greater than a quantity of bits comprised in the second data, and a quantity of bits comprised in the first encoded sequence is equal to a quantity of bits comprised in the second encoded sequence; generating a symbol sequence by performing a PAM-4 modulation on an input signal, the first encoded sequence corresponds to a high bit of the input signal, and the second encoded sequence corresponds to a low bit of the input signal; and sending the symbol sequence. The method helps reduce a quantity of redundant bits, helps improve a code rate, and can reduce redundant information carried in a modulated symbol sequence.

摘要： A data sending method, where the method includes receiving, by a forwarding device using a first flexible Ethernet (FlexE) group and in multiple timeslots included in a first timeslot set, multiple first encoded data blocks from a physical coding sublayer (PCS), determining, by the forwarding device according to the timeslots included in the first timeslot set and the first FlexE group, a second FlexE group and multiple timeslots included in a second timeslot set, and sending, by the forwarding device, the first encoded data blocks using the second FlexE group and in the timeslots included in the second timeslot set. The forwarding device does not need to process the first encoded data blocks in a conventional layer 2 or layer 3 forwarding mode. Therefore, a processing delay can be reduced, and a transmission delay can be reduced.
