1. 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
