Abstract: A path detection method includes a source node that sends a first detection packet including multipath detection indication information and detection data collection indication information, to detect a plurality of paths from the source node to a destination node. A first node directly sends the first detection packet including the multipath detection indication information and the detection data collection indication information to a next-hop node such that the next-hop node of the first node collects detection data in a manner of the first node and no path from the source node to the destination node is missed.

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: In a forwarding parameter obtaining method, a first forwarding device receives a first data packet sent by a second forwarding device on a forwarding path, where the first data packet includes a forwarding parameter monitoring instruction, and the forwarding path is used to forward the first data packet. The first forwarding device obtains, according to the forwarding parameter monitoring instruction, a forwarding parameter used when the first forwarding device forwards the first data packet. The first forwarding device sends the forwarding parameter to a telemetry analysis apparatus.
