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: A method for updating route information includes a monitored network element establishes a Border Gateway Protocol (BGP) Monitoring Protocol (BMP) connection to a monitoring network element, and sends a first message to the monitoring network element when detecting a synchronization requirement of BGP route information, where the first message instructs the monitoring network element to update a BGP route information set, and the BGP route information set includes at least one piece of BGP route information. The first message indicates an update set, and the update set updates the BGP route information set.

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: 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.
