    Abstract: A network device obtains Border Gateway Protocol (BGP) flow specification (FlowSpec) information, and generates, based on the BGP FlowSpec information, a first forwarding information base (FIB) table entry including a first prefix and an action, where the BGP FlowSpec information indicates to perform an action on traffic matching a filter condition, where the filter condition includes an attribute of a destination address, where the first FIB table entry indicates the network device to perform the action on the traffic matching the first prefix, and where an attribute of the first prefix is the same as the attribute of the destination address in the filter condition.

    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.

    Abstract: This application provides a route event record entry processing method, a network device, and a control device. The method includes: obtaining, by a network device, first information and second information that correspond to a route prefix, where the first information is used to indicate information about a first route policy for the route prefix, and the second information is used to indicate attribute information obtained after processing the route prefix by using the first route policy; and generating, by the network device, a route event record entry for the route prefix based on the first information and the second information, where the route event record entry includes the route prefix, the first information, and the second information.

    Abstract: This application discloses a packet sending method, a network device, and a computer storage medium, and pertains to the field of communications technologies. The method includes: generating, by a network device, a first packet, where the first packet includes a field used to indicate a first protocol, the first packet further includes a field carrying data of the first protocol, and a protocol followed by the first packet is different from the first protocol; and sending, by the network device, the first packet to a peer network device. Because the protocol followed by the first packet is different from the first protocol, regardless of which protocol the first protocol is specifically, the data of the first protocol may be exchanged by using the first packet. In other words, this application provides a general protocol, to transmit the data of the first protocol. This improves packet sending flexibility.
