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: A BGP route identification method and apparatus are provided. A network device obtains a BGP route. The BGP route includes an autonomous system path attribute AS_PATH attribute, the AS_PATH attribute includes a first autonomous system number AS number, an AS number corresponding to an autonomous system that the network device is located in or manages is a second AS number, and the first AS number is equal to the second AS number. The network device determines, based on the first AS number and the second AS number, whether the BGP route is abnormal.

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.
