             Generic YANG Data Model for the Management of
      Operations, Administration, and Maintenance (OAM) Protocols
                 That Use Connectionless Communications

Abstract

   This document presents a base YANG Data model for the management of
   Operations, Administration, and Maintenance (OAM) protocols that use
   connectionless communications.  The data model is defined using the
   YANG data modeling language, as specified in RFC 7950.  It provides a
   technology-independent abstraction of key OAM constructs for OAM
   protocols that use connectionless communication.  The base model
   presented here can be extended to include technology-specific
   details.

   There are two key benefits of this approach: First, it leads to
   uniformity between OAM protocols.  Second, it supports both nested
   OAM workflows (i.e., performing OAM functions at the same level or
   different levels through a unified interface) as well as interactive
   OAM workflows (i.e., performing OAM functions at the same level
   through a unified interface).
