Claim 8:
9. A method, comprising:
sending, by a controller, a traffic statistics collection instruction to a first network device in a bit index explicit replication (BIER) domain, wherein the traffic statistics collection instruction identifies a multicast source group of first multicast data, and the traffic statistics collection instruction instructs the first network device to perform traffic statistics collection on a first BIER packet that belongs to the multicast source group, and wherein the first network device is an ingress device in the BIER domain;
receiving, by the controller, multicast flow information and a traffic statistics collection result of the first BIER packet that are sent by the first network device, wherein the multicast flow information identifies a multicast flow to which the first BIER packet belongs; and
performing, by the controller, traffic analysis on the first BIER packet based on the multicast flow information and the traffic statistics collection result of the first BIER packet.
