Subject/title: Operations, Administration and Maintenance mechanism for MPLS-TP in Packet Transport Network (PTN)
Status: Approved on 2012-11-20

Summary: This Recommendation specifies mechanisms for user-plane OAM (Operations, Administration and Maintenance) in MPLS-TP networks to meet the MPLS-TP OAM requirements defined in [IETF RFC 5860]. It also specifies the MPLS-TP OAM packet formats, syntax and semantics of MPLS-TP OAM packet fields. The OAM mechanisms defined in this Recommendation assume common forwarding of the MPLS-TP user packets and MPLS-TP OAM packets. In transport networks, the OAM return path is always in band. The MPLS-TP OAM mechanisms as described in this Recommendation apply to co-routed bidirectional point-to-point MPLS-TP connections. Unidirectional point-to-point and point-to-multipoint MPLS-TP connections will be addressed in a future version of this Recommendation. This Recommendation is compliant with the transport profile of MPLS as defined by the IETF. In the event of a misalignment in MPLS-TP related architecture, framework, and protocols between this ITU-T Recommendation and the normatively referenced IETF RFCs, the RFCs will take precedence.
