Introduction Deterministic Networking (DetNet) is a service that can be offered by a network to DetNet flows. DetNet provides these flows extremely low packet loss rates and assured maximum end-to-end delivery latency. General background and concepts of DetNet can be found in [RFC8655]. To carry DetNet MPLS flows with full functionality at the DetNet layer over an IP network, the following components are required (these are a subset of the requirements for MPLS encapsulation listed in [I-D.ietf-detnet-mpls]): 1. A method for identifying DetNet flows to the processing element. 2. A method for carrying the DetNet sequence number. 3. A method for distinguishing DetNet OAM packets from DetNet data packets. 4. A method for carrying queueing and forwarding indication. These requirements are satisfied by the DetNet over MPLS Encapsulation described in [I-D.ietf-detnet-mpls] and they are partly Varga, et al.
