Optimizing network latency rather than throughput can lead to a significantly improved user experience for time-critical applications. Low Latency, Low Loss, and Scalable Throughput (L4S) technology, introduced in RFC 9330, uses Explicit Congestion Notification (ECN) bits by marking packets suffering potential congestion in the network. L4S operates as a congestion-control mechanism, using markers within the data packets to detect and promptly respond to congestion conditions. This feedback loop enables devices (e.g., endpoints such as client devices and server devices) to adjust data flow in real-time, preventing bottlenecks and ensuring smoother transmission. RFC 5129 describes a mechanism for supporting ECN in the Multiprotocol Label Switching (MPLS) data plane. That mechanism is based on the codepoints that take part in the Traffic Class (TC) field and, thus, prevent the use of TC field for traffic differentiation. This document defines how ECN can be supported in the MPLS data plane using the MPLS Network Actions technology. 03 Explicit Congestion Notification Using MPLS Network Actions urn:datatracker-ietf-org:event:1206656 2026-07-06T20:34:01.940534+00:00 2026-07-06T20:34:01.940534+00:00 Greg Mirsky New version accepted (logged-in submitter: Greg Mirsky) new_submission none active idexists Explicit Congestion Notification Using MPLS Network Actions urn:datatracker-ietf-org:event:1206655 2026-07-06T20:34:01.879028+00:00 2026-07-06T20:34:01.879028+00:00 Greg Mirsky Uploaded new revision new_submission none active idexists Supporting In Situ Operations, Administration, and Maintenance Using MPLS Network Actions urn:datatracker-ietf-org:event:1205786 2026-07-06T13:54:09.891955+00:00 2026-07-06T13:54:09.891955+00:00 Haomian Zheng Request for Early review by RTGDIR is assigned to Matthew Bocci assigned_review_request ietf mpls Adrian Farrel active idexists wg-doc Signaling Optimization Objective and Bounded Metrics for MPLS Fast Reroute Backup LSP Tunnels urn:datatracker-ietf-org:event:1204963 2026-07-05T17:55:14.849131+00:00 2026-07-05T17:55:14.849131+00:00 Vishnu Beeram New version available: <b>draft-deshmukh-mpls-frr-ext-02.txt</b> new_revision none active idexists This document introduces RSVP-TE signaling procedures that enable the head-end Label Switched Router (LSR) of a local-protection-desiring Label Switched Path (LSP) to influence the optimization objective and bounded metric constraints used for the path computation of a backup LSP tunnel at a Point of Local Repair (PLR). 02 Signaling Optimization Objective and Bounded Metrics for MPLS Fast Reroute Backup LSP Tunnels urn:datatracker-ietf-org:event:1204962 2026-07-05T17:55:14.845589+00:00 2026-07-05T17:55:14.845589+00:00 Vishnu Beeram New version accepted (logged-in submitter: Vishnu Beeram) new_submission none active idexists Signaling Optimization Objective and Bounded Metrics for MPLS Fast Reroute Backup LSP Tunnels urn:datatracker-ietf-org:event:1204961 2026-07-05T17:55:14.731786+00:00 2026-07-05T17:55:14.731786+00:00 Vishnu Beeram Uploaded new revision new_submission none active idexists Supporting In Situ Operations, Administration, and Maintenance Using MPLS Network Actions urn:datatracker-ietf-org:event:1204892 2026-07-05T11:06:43.734140+00:00 2026-07-05T11:06:43.734140+00:00 Rakesh Gandhi New version available: <b>draft-ietf-mpls-mna-ioam-06.txt</b> new_revision ietf mpls Adrian Farrel active idexists wg-doc In situ Operations, Administration, and Maintenance (IOAM), defined in RFC 9197, is an on-path telemetry method to collect and record the operational state and telemetry information using, for example, Pre- allocated, Proof-of-Transit, Edge-to-Edge, or Incremental IOAM Options that can be used to calculate various performance metrics. RFC 9326 defines the IOAM Direct Export (IOAM-DEX) Option in which the operational state and telemetry information are collected according to the specified profile and exported in a manner and format defined by a local policy on each node along the path. MPLS Network Actions (MNA) techniques are meant to indicate actions to be performed on any combination of Label Switched Paths, MPLS packets, and the node itself, and to transfer data needed for these actions. This document explores the MNA mechanisms to collect and transport the on-path operational state, and telemetry information using IOAM data fields, including the IOAM-DEX Option. 06 Supporting In Situ Operations, Administration, and Maintenance Using MPLS Network Actions urn:datatracker-ietf-org:event:1204891 2026-07-05T11:06:43.730958+00:00 2026-07-05T11:06:43.730958+00:00 Rakesh Gandhi New version accepted (logged-in submitter: Rakesh Gandhi) new_submission ietf mpls Adrian Farrel active idexists wg-doc Supporting In Situ Operations, Administration, and Maintenance Using MPLS Network Actions urn:datatracker-ietf-org:event:1204890 2026-07-05T11:06:43.680673+00:00 2026-07-05T11:06:43.680673+00:00 Rakesh Gandhi Uploaded new revision new_submission ietf mpls Adrian Farrel active idexists wg-doc Operations, Administration and Maintenance (OAM) for Network Resource Partition (NRP) in MPLS Network urn:datatracker-ietf-org:event:1204027 2026-07-03T01:01:00.111187+00:00 2026-07-03T01:01:00.111187+00:00 Changwang Lin New version available: <b>draft-gong-mpls-nrp-oam-mpls-03.txt</b> new_revision none active idexists A Network Resource Partition (NRP) represents a subset of network resources and associated policies within the underlay network.
