Abstract: 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.

Abstract: This application discloses a network slice information transmission method and apparatus. For example, a controller performs slice division on a network based on a service requirement and then obtains slice information, and sends the slice information to a first network device in the network by using a path computation element protocol (PCEP) packet, which includes first slice information corresponding to the first network device. After receiving the PCEP packet, the first network device parses the PCEP packet to obtain the first slice information, and further performs network slice configuration based on the first slice information. That is, in this application, the controller delivers the slice information by using the PCEP packet, so that after obtaining the PCEP packet, the first network device can obtain the first slice information corresponding to the first network device in a timely manner and perform network slice configuration without waiting for a configuration command.

Abstract: The technology of this application relates to an information processing method, apparatus, and system. The method includes a controller determining network slice information corresponding to a first network device. The controller sends a border gateway protocol (BGP) packet to the first network device, where the BGP packet includes the network slice information, and the network slice information is used by the first network device to configure a network slice. According to the technical solution provided in this application, efficiency of delivering network slice information can be improved.
