摘要： This application provides a method for forwarding a service packet, a method for sending an SR policy, a device, and a system, and belongs to the field of network technologies. In the solution provided in this application, a network device may forward, according to a first candidate path in an SR policy through a sub-interface corresponding to a first network slice, a service packet, and the first candidate path and a first identifier of a first network slice corresponding to the first candidate path are encapsulated in the service packet. In this way, it may be ensured that the network device that receives the service packet can also continue to forward, according to the first candidate path, the service packet through the sub-interface corresponding to the first network slice. In this way, a network slice technology and the SR policy are combined, which effectively improves flexibility of forwarding the service packet.

摘要： This application belongs to the field of communication technologies, and discloses a packet transmission method and apparatus, a device, and a computer-readable storage medium. An example is used in which the method is applied to a first communication device serving as an intermediate node in a transmission process. The method includes: The first communication device first obtains a first packet; selects, based on a network quality condition corresponding to the first packet, a first physical interface from at least two physical interfaces corresponding to a logical interface to send the first packet. A network quality parameter of the first physical interface corresponds to the network quality condition. In this application, the network quality parameter of the first physical interface for sending the first packet corresponds to the network quality condition. Therefore, cases such as a large delay and a high packet loss rate are reduced in a process of transmitting the first packet.
