The mechanism encodes a priority mapping table index in the QUIC Destination Connection ID (DCID), enabling host NICs or user gateways to translate QUIC-layer service priority information into network-layer QoS mechanisms (DSCP/ToS per RFC 2474) and traffic engineering policies (SRv6 TE, MPLS TE, etc.) for end-to-end QoS enforcement. Stream IDs carry endpoint priority information for local scheduling. The mechanism supports host-side, network-side, and coordinated deployment modes with no intrusion into the host protocol stack.}, }
