Abstract: An in-situ flow detection method and a related device are disclosed pertaining to the field of communication technologies. The method includes, when a tunnel type of an uplink tunnel of a first node is inconsistent with a tunnel type of a downlink tunnel of the first node, the first node generates a second traffic detection header based on a first traffic detection header. Therefore, the first node can continue to send, to a next hop without using an IFIT indication delivered by a control node, a packet that carries a traffic detection header, so that in-situ flow detection across tunnels of different types is implemented.

Abstract: A method for detecting a multicast service flow includes receiving, by a first node, a multicast service flow from a multicast source; encapsulating, by the first node, an In-situ Flow Information Telemetry (IFIT) extension header into a data packet in the multicast service flow, where the IFIT extension header includes a first detection identifier, and the first detection identifier is used to identify the detected multicast service flow; copying, by the first node according to a quantity of next-hop second nodes of the first node, the data packet encapsulated with the IFIT extension header; and sending, by the first node to each next-hop second node, the data packet encapsulated with the IFIT extension header. The first node is a head node in a multicast detection domain.

Abstract: A method according to embodiments of this application includes: A first network device sends a first packet to a second network device, where the first packet includes first indication information, and the first indication information indicates a support status of an iFIT capability corresponding to the first network device or a first service module included in the first network device. The first network device sends the packet to the second network device, to notify the support status of the IFIT capability of the first network device. In this way, the second network device can determine, based on the iFIT capability of the first network device, whether to encapsulate a measurement header, to avoid that a service packet cannot be correctly processed because the first network device cannot strip the measurement header from the service packet.

Abstract: Embodiments of this application disclose a network traffic migration method and apparatus. The network traffic migration method includes: obtaining a bandwidth usage parameter value of each of M vBNG-UP network elements, where M is an integer greater than 1; when a bandwidth usage parameter value of a first vBNG-UP network element reaches a first threshold, determining a second vBNG-UP network element based on the sum of bandwidths occupied by to-be-migrated network traffic of one or more terminal devices in a first device group on the first vBNG-UP network element and a bandwidth usage parameter value of one or more vBNG-UP network elements in a vBNG-UP network element group; and migrating the to-be-migrated network traffic of the terminal devices in the first device group to the second vBNG-UP network element.
