摘要： This application provides a packet forwarding method, a forwarding device, and a network device. The method includes: receiving N Time-Sensitive Networking TSN packet flows, where each of the N TSN packet flows is corresponding to a constraint condition that defines duration of a single cycle, a maximum quantity of packets that are allowed to be transmitted in a single cycle, and a maximum length of a single packet; and forwarding the N TSN packet flows based on a new constraint condition that defines duration of a single cycle, a maximum quantity of packets that are allowed to be transmitted in a single cycle, and a maximum length of a single packet, where each TSN packet flow is forwarded in a case in which a corresponding constraint condition is complied with, and the new constraint condition is determined based on the constraint condition corresponding to each of the N TSN packet flows. The method in this application helps reduce jitter of a packet during forwarding, and can improve resource utilization and forwarding efficiency of forwarding the packet by a system.

摘要： This application discloses a data transmission method and apparatus, relates to computer network technologies, and is used to prevent a network device from forwarding an Ethernet frame in which an error occurs. A specific solution is as follows: A network device receives an Ethernet frame, and checks a destination MAC address based on a first 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. The embodiments of this application are used in a process of forwarding the Ethernet frame.
