Claim 12:
13. A packet forwarding node apparatus, comprising:
a first device configured to carry, 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 send the multicast packet carrying the BIER header information; and
a second device configured to acquire, from the received multicast packet carrying the BIER header information, the DetNet configuration information, and process the packet according to the DetNet configuration information; wherein before sending the multicast packet carrying the BIER header information, 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.
