1. Introduction
[RFC8655] introduces and explains Deterministic Networks (DetNet)
architecture and how the Packet Replication and Elimination function
(PREF) can be used to ensure low packet drop ratio in DetNet domain.
Operations, Administration and Maintenance (OAM) protocols are used
to detect, localize defects in the network, and monitor network
performance. Some OAM functions, e.g., failure detection, work in
the network proactively, while others, e.g., defect localization,
usually performed on-demand. These tasks achieved by a combination
of active and hybrid, as defined in [RFC7799], OAM methods.
This document lists the functional requirements toward OAM for DetNet
domain. The list can further be used for gap analysis of available
OAM tools to identify possible enhancements of existing or whether
new OAM tools are required to support proactive and on-demand path
monitoring and service validation. Also, this document defines
format and use principals of the DetNet service Associated Channel
over a DetNet network with the MPLS data plane
