Claim 4:
5. A packet forwarding method applied to a second device, the method comprising:
acquiring, from a received multicast packet carrying header information based on Bit Index Explicit Replication (BIER), Deterministic Networking (DetNet) configuration information carried in the BIER header information, wherein the DetNet configuration information carries a flow ID through which one BIER multicast flow is capable of being uniquely identified, the flow ID is ID information defined corresponding to a packet type, the packet type comprising an IPv6 packet, a multiprotocol label switching protocol (MPLS) packet, or an Ethernet packet,
and wherein in a case where the BIER-based multicast packet is an MPLS packet, the flow ID is an MPLS label or a mapping value of the MPLS label; and
in a case where the BIER-based multicast packet is an IPv6 packet or an Ethernet packet, the flow ID is a unique flow ID assigned to the BIER multicast flow; and

processing the packet according to the DetNet configuration information.
