                     draft-ietf-ippm-ioam-flags-00

Abstract

   In-situ Operations, Administration, and Maintenance (IOAM) records
   operational and telemetry information in the packet while the packet
   traverses a path between two points in the network.  This document
   presents new flags in the IOAM Trace Option headers.  Specifically,
   the document defines the Loopback and Active flags.

1.  Introduction

   IOAM [I-D.ietf-ippm-ioam-data] is used for monitoring traffic in the
   network by incorporating IOAM data fields into in-flight data
   packets.

   IOAM data may be represented in one of four possible IOAM options:
   Pre-allocated Trace Option, Incremental Trace Option, Proof of
   Transit (POT) Option, and Edge-to-Edge Option.  This document defines
   two new flags in the Pre-allocated and Incremental Trace options: the
   Loopback and Active flags.
