       Segment Routing Header encapsulation for In-situ OAM Data
                     draft-ali-spring-ioam-srv6-00

Abstract

   In-situ Operations, Administration, and Maintenance (IOAM) records
   operational and telemetry information in the data packet while the
   packet traverses a path between two points in the network.  This
   document defines how IOAM data fields are transported as part of the
   Segment Routing with IPv6 data plane (SRv6) header.

1.  Introduction

   In-situ Operations, Administration, and Maintenance (IOAM) records
   OAM information within the packet while the packet traverses a
   particular network domain.  The term "in-situ" refers to the fact
   that the IOAM data fields are added to the data packets rather than
   being sent within probe packets specifically dedicated to OAM.

   This document defines how IOAM data fields are transported as part of
   the Segment Routing with IPv6 data plane (SRv6) header
   [I-D.6man-segment-routing-header].

   The IOAM data fields carried are defined in
   [I-D.ietf-ippm-ioam-data], and can be used for various use-cases
   including Performance Measurement (PM) and Proof-of-Transit (PoT).
