    Retrieval Methods YANG Data Model for Connectionless Operations,
             Administration, and Maintenance(OAM) protocols
           draft-ietf-lime-yang-connectionless-oam-methods-08

Abstract

   This document presents a retrieval method YANG Data model for
   connectionless OAM protocols.  It provides technology-independent RPC
   operations for connectionless OAM protocols.  The retrieval methods
   model presented here can be extended to include technology specific
   details.  This is leading to uniformity between OAM protocols and
   support both nested OAM workflows (i.e., performing OAM functions at
   different levels through a unified interface) and interacting OAM
   workflows ( i.e., performing OAM functions at same levels through a
   unified interface).

1.  Introduction

   Operations, Administration, and Maintenance (OAM) are important
   networking functions that allow operators to:

   1.  Monitor reachability of destinations (Reachability Verification,
       Continuity Check).

   2.  Troubleshoot failures (Fault verification and localization).

   3.  Monitor Performance
