Abstract: This application discloses a packet forwarding method and apparatus, a system, a device, and a storage medium. The method is applied to an in-vehicle network and includes: obtaining, by a network device, a plurality of packets carried on an Ethernet link in the in-vehicle network, where the plurality of packets are packets of one or more application categories; determining a traffic class of each packet based on an application category of each packet in the plurality of packets; adding each packet to a forwarding queue corresponding to the traffic class based on the traffic class of each packet; and scheduling and forwarding packets in all forwarding queues based on an absolute priority and a traffic class corresponding to each forwarding queue, and using a shaper in a forwarding queue of at least one traffic class in intermediate traffic classes in the scheduling and forwarding process.

Abstract: This application discloses a service level configuration methods and apparatuses, and belongs to the field of communications network technologies. According to an example method, a target service level used by a first forwarding node to forward a data flow is directly determined based on a transmission parameter of the data flow and service level information of the first forwarding node, and service level configuration is performed on the first forwarding node. Because a transmission parameter of the target service level of the first forwarding node and the transmission parameter of the data flow meet a first target condition, if the first target condition is a delay requirement required by a special service and the first forwarding node transmits the data flow by using the target service level, transmission of the data flow may meet the delay requirement required by the special service.
