Subject: WG Last Call: draft-ietf-mpls-mna-ioam-11 (Ends 2026-09-02)

We have all of the IPR response, so...

This message starts a WG Last Call for:
draft-ietf-mpls-mna-ioam-11

This Working Group Last Call ends on 2026-09-02

Abstract:
   In situ Operations, Administration, and Maintenance (IOAM), defined
   in RFC 9197, collects operational and telemetry information in the
   packet using IOAM-Data-Fields while the packet traverses a path
   between two points in the network.  Several IOAM Option-Types are
   available, for example, Pre-allocated Trace, Proof of Transit (POT),
   Edge-to-Edge (E2E), and Incremental Trace, that can be used to
   collect information for calculating various performance metrics.  RFC
   9326 defines the IOAM Direct Export (IOAM-DEX) Option-Type, which is
   used as a trigger for IOAM data to be directly exported or locally
   aggregated without being pushed into in-flight data packets.

   MPLS Network Actions (MNA) techniques indicate actions to be
   performed on any combination of Label Switched Paths, MPLS packets,
   and the node itself, and to transport data needed for these actions.
   This document employs the MNA mechanisms to collect and transport the
   operational state and telemetry information using IOAM-Data-Fields as
   well as IOAM-DEX.
