    Abstract: This application discloses a VXLAN packet transmission method, a network device, and a system. After receiving a first packet, a first network device obtains a VNI corresponding to the first packet. The first network device encapsulates the VNI in an IPV6 header by encapsulating the IPV6 header in the first packet, to obtain a second packet. The first network device sends the second packet to a second network device, so that the second network device forwards the packet based on the VNI included in the IPV6 header. In this application, the IPV6 header is used to carry the VNI, and no additional UDP header needs to be encapsulated to carry the VNI.

    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.

    Abstract: The present disclosure discloses a packet processing method, device, and system. The system includes: a controller, configured to: allocate a service label to a service processing manner of an FEC, establish a mapping relationship between the service label and the service processing manner, send the service label to a source node, and send the mapping relationship to a destination node; the source node, configured to: receive the service label sent by the controller, receive a first packet, insert the service label to the first packet to obtain a second packet, and send the second packet to the destination node; the destination node, configured to: receive the mapping relationship sent by the controller, receive the second packet sent by the source node, and pop the service label from the second packet according to the mapping relationship, to obtain the first packet.

    Abstract: A network device creates a virtual border gateway protocol (BGP) peer and the BGP peer is enabled all BGP capability data configured in the network device. A BGP monitoring protocol (BMP) module of the network device acquires the enabled BGP capability by using a BGP message. According to the solution of the embodiment, the network device obtains all BGP capabilities configured in the network device and sends all the BGP capabilities to a monitoring server, so that the monitoring server can fully understand actual capability supported by the entire network, further providing an effective basis for deployment of and decision on the entire network.

    Abstract: A mechanism for adaptively performing in-band network telemetry (INT) by a network controller is disclosed. The mechanism includes receiving one or more congestion indicators from a collector. An adjusted sampling rate is generated. The adjusted sampling rate is a specified rate of insertion of instruction headers for INT and is generated based on the congestion indicators. The adjusted sampling rate is transmitted to a head node, which is configured to perform INT via instruction header insertion into user packets.
