Gap Analysis for Layer and Technology Independent OAM Management in the
                        Multi-Layer Environment

Abstract

   This draft analyses the existing management plane OAM related works
   in different SDOs, against the key objectives of Layer Independent
   OAM Management (LIME), to find the gap between them.  The results can
   be used as the guidance for further work.  This gap analysis is not
   targeted at L0-L2 transport OAM in ITU-T, either technology specific
   or generic across those technologies.  Rather, it is intended to
   leverage knowledge from that domain for the benefit of developing
   generic layer independent OAM management for L3-L7 (and L2.5 MPLS
   OAM).

1.  Introduction

   Operations, Administration, and Maintenance (OAM) mechanisms are
   critical building blocks in network operations that are used for
   service assurance, fulfillment, or service diagnosis,
   troubleshooting, and repair.  The current practice is maintenance and
   troubleshooting are achieved per technology and per layer.  The
   operation process can be very cumbersome.  At present, within the
   L0-L2 technology domains, considerable effort has been expended in
   ITU-T to establish a coherent approach to OAM, including generic
