    Abstract: A method for processing a packet on an SR network is provided, including: receiving a packet, where a packet header of the packet includes a destination address field, a first pointer, a second pointer, and a list used to process the packet, the list includes a plurality of sequentially arranged identifiers, and a value of the first pointer and a value of the second pointer jointly indicate a location of a first identifier in the plurality of identifiers in the list; determining the first identifier based on the value of the first pointer and the value of the second pointer; and copying the first identifier to the destination address field. In this method, a CL pointer is set in the packet header to jointly form a two-dimensional pointer with an SL pointer, to indicate a location of a C-SID in a SID list.

    Abstract: Embodiments of this application disclose a packet sending method. A first IP packet may be obtained, where a packet header of the first IP packet includes a tenant identifier of a tenant corresponding to the first IP packet. After the first IP packet is obtained, the first IP packet is sent to a VAS device, where the VAS device is configured to perform, based on the tenant identifier, a value-added service corresponding to the tenant. Because the packet header of the first IP packet includes the tenant identifier of the tenant corresponding to the first IP packet, after receiving the first IP packet, the VAS device may obtain the corresponding tenant identifier of the tenant by parsing the first IP packet, and further perform, based on the tenant identifier, the value-added service corresponding to the tenant.

    Abstract: Embodiments of this application disclose a method for verifying an SRv6 packet. An egress node of an IPsec tunnel may receive an SRv6 packet, where the SRv6 packet is a packet encapsulated in an IPsec transport mode. The SRv6 packet includes an AH and at least one SRH. The SRv6 packet carries first indication information, where the first indication information indicates the egress node to perform AH verification on the SRv6 packet. A verification range of the AH verification includes the at least one SRH.

    Abstract: A packet forwarding method is disclosed. The method includes: After an edge node in a trusted domain receives an SRv6 packet whose destination address is a BSID, the edge node may verify the packet based on a BSID in the packet and a destination field in an SRH of the packet. If the packet passes the verification, the edge node forwards the packet. If the packet fails the verification, the edge node discards the packet. Not only a node outside the trusted domain is required to access the trusted domain by using the BSID, but also the packet entering the trusted domain needs to be verified with reference to the target field in the segment routing header.

    Abstract: A packet sending method and a related device are disclosed. The method includes: A network device obtains a first packet, where an internet protocol extension header of the first packet includes a first identifier, and the first identifier indicates a service requirement corresponding to the first packet. The network device determines, based on the first identifier and a second identifier, path indication information corresponding to the first packet, where a destination address of the first packet includes the second identifier, and the path indication information herein includes one or more of a network slice identifier and a segment identifier list. The network device updates the first packet based on the path indication information to obtain a second packet, and sends the second packet.

    Abstract: A packet processing method includes a first network device receiving a first packet, where the first packet includes a plurality of segment identifier (SID) lists, the plurality of SID lists include a primary SID list and at least one secondary SID list. The at least one secondary SID list includes a first secondary SID list, and the first secondary SID list is a backup of the primary SID list. The first network device processes the first packet based on the primary SID list. When a forwarding path indicated by a segment identifier list is faulty, data packet forwarding processing can still be implemented in the segment routing network.

    Abstract: A packet sending method and apparatus, a network device, a system, and a storage medium are disclosed in the field of communication technologies. An edge network device of a tier-1 carrier that has upgraded to an SRv6 network establishes a mapping relationship between a segment identifier and an MPLS label. After receiving a packet that carries an MPLS label and that is sent by a network device of a tier-2 carrier, the edge network device generates, based on the mapping relationship, a packet carrying a segment identifier. The packet carrying the segment identifier is forwarded in the SRv6 network of the tier-1 carrier.
