Abstract: A controller obtains request messages. The controller creates at least two network slices based on the request messages. The at least two network slices include a first network slice and a second network slice. The first network slice and the second network slice share a resource object at each layer in a network slice architecture. The controller sends information including information about the first network slice and information about the second network slice to one or more target forwarding devices. The information about the first network slice indicates a resource object that is at each layer in the network slice architecture and that is associated with the first network slice. The information about the second network slice indicates a resource object that is at each layer in the network slice architecture and that is associated with the second network slice.

Abstract: This application discloses a transmission path fault processing method and apparatus, and a system, to resolve a problem that a packet fails to be forwarded because a previous-hop node of a faulty node cannot process a stitching label. The method includes: receiving, by a first network device, a stitching label and a stitching label stack list corresponding to the stitching label that are sent by a stitching network device; determining, in a process of sending a packet through a primary path, that the stitching network device is faulty, where the packet includes a label stack list, and the stitching network device is a next-hop network device of the first network device; and replacing, by the first network device, the stitching label in the label stack list with the stitching label stack list, and switching, based on the updated label stack list, the packet to a backup path for sending.

Abstract: Embodiments of this application provide a network optimization method, a network optimization system, and a network device, and relate to the communications field. A first network device adjusts, if it is detected that a communications link between the first network device and a second network device is in an abnormal state, a metric of at least one data flow received by the first network device; and the first network device selects a transmission path for the at least one data flow based on adjusted metric, and transmits the at least one data flow to the selected transmission path. In this way, load of the communications link is reduced, and the communications link is restored to a normal state.

Abstract: In a data transmission control method, one or more pieces of identification information are added to determine an interface resource object for forwarding a data packet on an interface of a network device. The added one or more pieces of identification information include one piece of global identification information. The global identification information may correspond to a network slice, and different network slices correspond to different values of global identification information. A global network identifier corresponds to one or more interface resource objects. One interface resource object may be occupied by one network slice alone, or one interface resource object may be jointly shared by a plurality of network slices.

Abstract: This application describes a tunnel establishment method. The method may include receiving, by a first network device, a first request message sent by a previous-hop network device, where the first request message is used to request to obtain an RSVP-TE label of the first network device, the first network device supports RSVP-TE and SR-TE, and the previous-hop network device supports RSVP-TE. The method may also include that when the first network device determines that at least one network device in downstream network devices of the first network device on a path of a to-be-established tunnel supports SR-TE, establishing an SR-TE tunnel from the first network device to a second network device, and generating a tunnel identifier used to identify the SR-TE tunnel. Furthermore, the method may include sending a first response message to the previous-hop network device, where the first response message includes the tunnel identifier.

Abstract: A communication method implemented by a first network device, the method includes receiving, by the first network device, a first packet. The first packet may include a first segment identifier (SID) and a second SID. Determining, by the first network device whether the first SID is unavailable. If the first SID is unavailable, the first network device obtains the second SID based on the first SID, and updates a destination address in the first packet with the second SID, to generate a second packet.
