              Ethernet Encapsulation for In-situ OAM Data
                      draft-weis-ippm-ioam-eth-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
   outlines how encapsulations using an EtherType to identify IOAM data
   fields as the next header in a packet.

1.  Introduction

   In-situ Operations, Administration, and Maintenance (IOAM) records
   operational and telemetry information in 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
