1.  Introduction

   [I-D.xuclad-spring-sr-service-programming] defines data plane
   functionality required to implement service segments and achieve
   service programming in SR-enabled MPLS and IP networks, as described
   in the Segment Routing architecture.  This document defines the
   Operations, Administrations and Maintenance (OAM) for service
   programming in SR-enabled MPLS and IP networks.

2.  Requirements notation

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].
