Claim 0:
1. A packet forwarding method applied to a first device, the method comprising:
carrying, according to Deterministic Networking (DetNet) requirements for a multicast packet based on Bit Index Explicit Replication (BIER), corresponding DetNet configuration information in BIER header information of the multicast packet; and
sending the multicast packet carrying the BIER header information,
wherein before sending the multicast packet carrying the BIER header information, the method further comprises:
carrying in the DetNet configuration information, 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.
