    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.

    Abstract: A packet processing method includes receiving, by a first network node a packet from a second network node, where the packet includes one or more type-length-values (TLVs) that need to be processed by a network node and indication information indicating that a network node on a packet forwarding path needs to process at least one TLV in the one or more TLVs; determining, by the first network node based on the indication information, that the first network node needs to process a first TLV; determining, by the first network node, the first TLV; and processing, by the first network node, the first TLV.

    Abstract: A first network device includes a processor and a memory having computer readable instructions stored thereon that, when executed by the processor, cause the first network device to obtain a Flow Specification (FlowSpec) rule with redirect indication information. The redirect indication information includes identification information identifying a first virtual private network (VPN) instance configured on a second network device. The indication information also includes instructions for the second network device to redirect data stream matching the FlowSpec rule to the first VPN instance. The first network device is also caused to advertise the FlowSpec rule with the redirect indication information to the second network device.

    Abstract: A segment routing device receives a first packet from a first network. A first packet header of the first packet includes a segment list. The segment list includes a plurality of sequentially arranged identifiers. The identifiers include a first-type identifier and a plurality of second-type identifiers. Network devices or links identified by the first-type identifier and the second-type identifier are respectively on the first network and a second network. A type of the first network is different from a type of the second network. The segment routing device encapsulates a second packet header for the first packet to form a second packet. The second packet header includes the plurality of second-type identifiers. The segment routing device sends the second packet to the second network.

    Abstract: A data packet detection method, a device, and a system are disclosed. The method includes: receiving first control information sent by a controller; receiving a first data packet sent by a previous-hop network device of a first network device, where the first data packet includes first detection information, and the first detection information includes a first detection node identifier, a first sequence number, and first collection information; determining, based on the first collection information, first collected data corresponding to the first collection information, and updating the first detection node identifier; and sending, to a next-hop network device of the first network device, the first data packet carrying the updated first detection information. This implements information telemetry on a data packet on a transmission path.
