Operations, Administration and Maintenance (OAM) for Deterministic
Networks (DetNet) with MPLS Data Plane
draft-ietf-detnet-mpls-oam-02
Abstract
This document defines format and use principals of the Deterministic
Network (DetNet) service Associated Channel (ACH) over a DetNet
network with the MPLS data plane. The DetNet service ACH can be used
to carry test packets of active Operations, Administration, and
Maintenance protocols that are used to detect DetNet failures and
measure performance metrics.

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.
Also, this document defines format and use principals of the DetNet
service Associated Channel over a DetNet network with the MPLS data
plane [I-D.ietf-detnet-mpls].
