 Generic YANG Data Model for Connectionless Operations, Administration,
                     and Maintenance(OAM) protocols
               draft-ietf-lime-yang-connectionless-oam-11

Abstract

   This document presents a base YANG Data model for connectionless
   Operations Administration, and Maintenance(OAM) protocols.  It
   provides a technology-independent abstraction of key OAM constructs
   for connectionless protocols.  The base 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 or same levels
   through a unified interface) and interacting OAM workflows ( i.e.,
   performing OAM functions at same levels through a unified interface).
