Abstract

   This draft specifies requirements for inter-carrier OAM supporting
   end-to-end OAM functionality and mechanisms development in a multi-
   operator environment. It reviews the already proposed OAM
   requirements addressed in IETF [RFC5706, RFC5860], ITU-T [Y.1730],MEF
   [MEFOAM] and IEEE [IEEE1, IEEE2] which were mainly proposed on a per
   transport technology basis, but aims to differentiate and focus on
   the requirements and additional requirements resulting from inter-
   operator considerations only.

INTERNET DRAFT       Inter-Carrier OAM Requirements     26 November 2012

1  Introduction

   Operation, Administration and Management (or Maintenance) (OAM), 
   functionality is important in network operation and management for
   simplifying network operations and to reduce cost. It supports
   capabilities for fault management (including fault detection, fault
   notification and fault isolation), as well as performance degradation
   awareness. In this draft a distinction is made with regards to what
   is considered as a subset of all OAM requirements relating to inter-
   operator considerations only and we refer to these as inter-carrier
   OAM requirements. More specifically these relate relate to end-to-end
   service delivery crossing domains and could be considered as agnostic
   to underlying transport technologies. Influencing further the
   requirements could be policies, QoS (SLA) agreements or commercial
