1. Operations, Administration, and Maintenance (OAM) in Segment Routing Networks with IPv6 Data plane (SRv6)

Publication URL: https://datatracker.ietf.org/doc/html/rfc9259


This document describes how the existing IPv6 OAM mechanisms can be used in an SRv6 network. The document also introduces enhancements for controller-based OAM mechanisms for SRv6 networks.

2. Segment Routing Header encapsulation for In-situ OAM Data

Publication URL: https://datatracker.ietf.org/doc/html/draft-ali-spring-ioam-srv6


This document defines how IOAM data fields are transported as part of the Segment Routing with IPv6 data plane (SRv6) header.

3. A Light Weight IOAM for SRv6 Network Programming

Publication URL: https://datatracker.ietf.org/doc/html/draft-li-spring-light-weight-srv6-ioam


This document defines a light weight IOAM method for SRv6 network programming. In this method, IOAM information is carried in the data packet by the SIDs in the SRH.

4. Performance Measurement Using Simple TWAMP (STAMP) for Segment Routing Networks

Publication URL: https://datatracker.ietf.org/doc/draft-ietf-spring-stamp-srpm


This document specifies procedure for sending and processing probe query and response messages for Performance Measurement (PM) in Segment Routing networks. The procedure uses the mechanisms defined in RFC 5357 (Two-Way Active Measurement Protocol (TWAMP) Light) and its extensions for Performance Measurement. The procedure specified is applicable to SR-MPLS and SRv6 data planes and is used for both Links and end-to-end SR Paths including SR Policies.

5. Simple TWAMP (STAMP) Extensions for Segment Routing Networks

Publication URL: https://datatracker.ietf.org/doc/html/draft-ietf-ippm-stamp-srpm


Segment Routing (SR) leverages the source routing paradigm. SR is applicable to both Multiprotocol Label Switching (SR-MPLS) and IPv6 (SRv6) forwarding planes. This document specifies Simple Two-Way Active Measurement Protocol (STAMP) extensions (as described in RFC 8762) for SR networks, for both the SR-MPLS and SRv6 forwarding planes, by augmenting the optional extensions defined in RFC 8972.

6. Bidirectional Forwarding Detection (BFD) for Segment Routing Policies for Traffic Engineering

Publication URL: https://datatracker.ietf.org/doc/html/draft-ali-spring-bfd-sr-policy


This document describes the use of Seamless BFD (S-BFD) mechanism to monitor the SR Policies that are used for Traffic Engineering (TE) in SR deployments.
