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.
