  Retrieval Methods YANG Data Model for the Management of Operations,
Administration, and Maintenance (OAM) Protocols that use Connectionless
                             Communications
           draft-ietf-lime-yang-connectionless-oam-methods-13

Abstract

   This document presents a retrieval method YANG Data model for
   connectionless OAM protocols.  It provides technology-independent RPC
   operations for OAM protocols that use connectionless communication.
   The retrieval methods model herein presented can be extended to
   include technology specific details.  There are two key benefits of
   this approach: First, it leads to uniformity between OAM protocols.
   And second, it support both nested OAM workflows (i.e., performing
   OAM functions at different or same levels through a unified
   interface) as well as interactive 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 network communications (i.e., Reachability Verification,
       Continuity Check)

   2.  Troubleshoot failures (i.e., Fault verification and Localization)
