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.
