1. A first node comprising:
a receiver configured to receive a multicast service flow from a multicast source, wherein the multicast service flow comprises a first data packet;
a processor coupled to the receiver and configured to:
encapsulate an In-situ Flow Information Telemetry (IFIT) extension header into the first data packet to obtain a second data packet, wherein the IFIT extension header comprises a first detection identifier identifying the multicast service flow; and
copy, according to a quantity of next-hop second nodes of the first node, the second data packet; and
a transmitter coupled to the processor and configured to send the second data packet to each of the next-hop second nodes.
