In a data transmission method, a first chip receives a first data stream sent by a second chip, where the first data stream is a data stream obtained through encoding by using a first forward error correction (FEC) code type; and the first chip 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.

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.

Forward error correction (FEC) code type conversion

This application relates to a slot negotiation method and a device. The method includes: A transmitter sends a first FlexE overhead frame to a receiver, to request active/standby calendar switching. When the receiver is in a restart state, the receiver does not respond to the received first FlexE overhead frame. In addition, the RX sends a routine update second FlexE overhead frame to the transmitter. Determining that the second FlexE overhead frame is not a response to the first FlexE overhead frame, the transmitter sends a third FlexE overhead frame to request active/standby calendar switching again. According to the method in this application, incorrect calendar switching on the transmitter side caused by a mistaken response of the receiver can be avoided. This reduces the likelihood of a service interruption caused by the existing slot negotiation mechanism.

An interface obtains basic page information from another interface. The basic page information includes N bits, the N bits include an FEC function indicator bit sequence including an FEC ability indicator bit and an FEC requested indicator bit. The interface determines, based on values of a plurality of bits in the N bits, an operation mode supported by the another interface. The FEC function indicator bit sequence includes a first FEC function indicator bit corresponding to m FEC abilities; or the FEC function indicator bit sequence includes a first FEC ability indicator bit corresponding to n FEC abilities, where both m and n are greater than or equal to 1. Because one FEC function indicator bit indicates more FEC abilities, N bits in a basic page can carry more information, so that a process of increasing auto-negotiation pages is slowed down, thereby avoiding impact on auto-negotiation efficiency.
