    Abstract: A method includes a network device receiving a plurality of fragments of an Ethernet frame, where the plurality of fragments include an initial fragment and a first fragment, and where the initial fragment includes a destination media access control (MAC) address field. In response to an error occurring in the Ethernet frame, the first fragment is changed to a second fragment, where the second fragment includes second type indication information (TII) and second to-be-transmitted data (TBTD), where the second TII indicates that a type of the second TBTD is a control character, where a value of first TBTD is different from a value of the second TBTD, and where the second TBTD indicates that an error occurs in the Ethernet frame. The network device sends the second fragment to a destination device.

    Abstract: A packet forwarding method includes a first network device receiving a first message from a second network device via a second egress port of the second network device, where the first message measures a phase difference, and where the phase difference is a phase difference between a switching time of one of a plurality of first buffers of a first egress port of the first network device and a switching time of one of a plurality of second buffers of the second egress port of the second network device with a link delay taken into consideration. The first network device determines the phase difference based on the first message. Then, the first network device schedules, based on the phase difference, a second data packet sent via the first egress port.

    Abstract: A packet forwarding method includes receiving N Time-Sensitive Networking (TSN) packet flows, where each of the N TSN packet flows corresponds to a constraint condition that defines duration of a cycle, a maximum quantity of packets that are allowed to be transmitted in the cycle, and a maximum length of a single packet, and forwarding the N TSN packet flows based on a new constraint condition, where the new constraint condition is based on the constraint condition corresponding to each of the N TSN packet flows and defines duration of a new cycle, a new maximum quantity of new packets that are allowed to be transmitted in the new cycle, and a new maximum length of a new packet, where each of the N TSN packet flows is forwarded in a case in which a corresponding constraint condition is complied with.

    Abstract: A network configuration method includes determining an end-to-end latency upper bound of data traffic between two end nodes, determining an end-to-end latency constraint of the data traffic between the two end nodes, determining, based on the end-to-end latency upper bound and the end-to-end latency constraint, for a first network shaper, at least one configuration parameter that satisfies the end-to-end latency constraint, and configuring the first network shaper for the data traffic based on the at least one configuration parameter such that the traffic after being shaped by the shaper satisfies the network latency constraint.

    Abstract: A network device receives an Ethernet frame, checks a destination media access control (MAC) address based on a first cyclic redundancy check (CRC) code, to determine whether an error occurs in the destination MAC address. If the network device determines that no error occurs in the destination MAC address, the network device forwards the Ethernet frame based on the destination MAC address. The Ethernet frame includes the destination MAC address, the first CRC code, and a payload, a parameter of the first CRC code includes the destination MAC address, and the parameter of the first CRC code does not include the payload.

    Abstract: An embodiment of the present invention discloses a data sending and receiving method. A first FEC unit of a sending device sends, by using a first channel, a first data stream on which first FEC encoding has been performed; a second FEC unit of the sending device sends, by using a second channel, a second data stream on which second FEC encoding has been performed; and the sending device performs interleaving on the first data stream and the second data stream, to obtain an output data stream, and sends the output data stream to a receiving device and error correction capability of a receiving device could be improved. In addition, in the present invention, an operation of writing by row and reading by column does not need to be performed. Therefore, no delay is generated.
