    Abstract: A packet sending method, apparatus, and system are disclosed, and related to the communications field. The method includes: A first device receives a first packet including a network identifier of a virtual local area network and an original packet. The first device obtains a first identifier based on an identifier of the second host and the network identifier, where the first identifier is used to identify a second device, a segment routing over internet protocol version 6 (SRv6) tunnel exists between the first device and the second device, the first identifier includes an indication identifier used to indicate the second device to convert a format of a packet forwarded through the SRv6 tunnel into a format of a packet forwarded through a first network virtualization over layer 3 (NVO3) tunnel. The first device sends an SRv6 packet including the first identifier and the original packet to the second device through the SRv6 tunnel.

    Abstract: A packet processing method implements a QoS guarantee. The method includes: obtaining a flow identification based on packet attribute information and a flow matching rule, generating a flow policy that includes a correspondence between the flow identification and a flow behavior, determining a forwarding path of a packet including the packet attribute information, sending the flow matching rule to an ingress device of the forwarding path, and sending the flow policy to a first network device on the forwarding path. The ingress device adds the flow identification to the packet including the packet attribute information, and sends the packet. The first network device receives the packet including the flow identification, obtains the flow behavior from the flow policy based on the flow identification, and processes the packet in a packet processing mode corresponding to the flow behavior.

    IPC: H04L69/22

    Abstract: This application provides a packet processing method, a device, and a system. The method includes a second network device receives an IPv6 packet sent by a first network device, where the IPv6 packet includes an IPv6 header and a first IPv6 extension header, and the first IPv6 extension header indicates that a network device receiving the IPv6 packet is to perform an action in the first IPv6 extension header on a data plane. The second network device performs the action in the first IPv6 extension header on the data plane of the second network device based on the IPv6 header and the first IPv6 extension header. This ensures that the network device receiving the IPv6 packet can normally forward the IPv6 packet.

    Abstract: This application provides a packet processing method, a device, a system, and a storage medium. A first network device receives an original packet, generates an IPv6 packet based on the original packet and endpoint group (EPG) information, where the IPv6 packet comprises an IPv6 extension header and the original packet, and the IPv6 extension header comprises the EPG information, and sends the IPv6 packet. A second network device receives the IPv6 packet; obtains the EPG information from the IPv6 extension header, and processes the IPv6 packet according to a group based policy corresponding to the EPG information.
