摘要： This application provides a packet processing method and a device. In this application, a control identifier field is added to a packet, and the control identifier field indicates whether forwarding of the packet is allowed when a resource corresponding to a slice identifier fails to be matched. The control identifier field and a slice identifier of a network slice are carried in the packet, so that the slice identifier and the control identifier field are transmitted on a network together. When a receive end fails to match the resource corresponding to the slice identifier, the receive end can discard the packet based on the control identifier field, instead of forwarding the packet by using routing information.

摘要： A user group-based packet forwarding method and a device are provided. The method includes: a first network device receives a first service packet sent by first user equipment, where the first service packet includes information about the first user equipment; the first network device determines whether the first network device includes a first user group corresponding to the information about the first user equipment; and the first network device determines, based on a determining result, a value of first group information, generates a first segment routing over internet protocol version 6 (SRv6) packet, and sends the first SRv6 packet to a second network device, where the first SRv6 packet includes the first group information and the first service packet, and the first group information indicates an interworking policy that is determined based on the first user group.

摘要： This application provides a packet forwarding method, apparatus, and system, and belongs to the field of communication technologies. In a scheme provided in this application, a packet includes both a destination address and a behavior instruction, and at least two nodes in a packet forwarding system may identify the behavior instruction in the packet, and may forward the packet based on a first forwarding behavior indicated by the behavior instruction. Therefore, when a plurality of nodes in the packet forwarding system each need to perform a forwarding behavior on the packet, an SID does not need to be allocated to each node, but only the behavior instruction needs to be carried in the packet.

摘要： Embodiments of this application provide a data transmission method and apparatus. The method includes receiving, by a first device, a data packet, and extracting first address information of the data packet, where the first address information indicates a VNF; retrieving, by the first device based on the first address information, an SRv6 tunnel policy that corresponds to the first address information and that is from a SRv6 tunnel list; obtaining, by the first device, a forwarding path corresponding to a first SRv6 VPN SID, where the forwarding path is used as a data transmission path when the first device communicates with a second device corresponding to the first SRv6 VPN SID; and forwarding, by the first device, the data packet to the VNF based on the forwarding path.

摘要： 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.

摘要： This application discloses a method, an apparatus, and a system for processing a transmission path fault. In this application, after a first network device receives a packet, and when the first network device determines that a third network device is faulty, a difference between an initial value of a segment routing global block SRGB of the first network device and an initial value of an SRGB of the third network device is determined, and a backup path is determined based on the difference and a backup forwarding table. The first network device sends a first packet based on the backup forwarding table.

摘要： A first network device receives an association relationship sent by a second network device, where the association relationship includes an association relationship between a first path and a second path. The first network device generates first routing information between the first network device and a target network device based on the association relationship, where the first routing information is used by the first network device to send a packet to the target network device through the first path, and when a cross-slice condition is met, the first routing information is used by the first network device to send a packet to the target network device through the second path.

摘要： A communication method includes a first network device obtaining a first route and a second route from a second network device. A first network segment corresponding to the first route is a subnet segment of a second network segment corresponding to the second route. The second route is an aggregated route, and the first route indicates that the first network segment is unreachable. The first network device switches a next hop of the aggregated route based on the first route.
