Classification: CPC H | IPC G  H

Claim 16:
17. A first network device, comprising:
a non-transitory memory storing instructions; and
a processor coupled to the non-transitory memory; wherein the instructions, when executed by the processor, cause the first network device to be configured to:
perform bit index explicit replication (BIER) encapsulation on first multicast data based on a traffic statistics collection instruction, to obtain a first BIER packet, wherein the traffic statistics collection instruction indicates a multicast source group of the first multicast data, and the traffic statistics collection instruction instructs to perform traffic statistics collection on the first multicast data that belongs to the multicast source group, and wherein the first network device is an ingress device in a BIER domain;
perform traffic statistics collection on the first BIER packet based on multicast flow information, to obtain a traffic statistics collection result of the first BIER packet, wherein the multicast flow information identifies a multicast flow to which the first BIER packet belongs; and
send the multicast flow information and the traffic statistics collection result of the first BIER packet to a controller.
