This Recommendation specifies mechanisms for operations@ administration and maintenance (OAM) for multi-protocol label switching transport profiles (MPLS-TPs) that can be applied in packet transport networks (PTN). It specifies mechanisms for user-plane OAM in MPLS-TP networks to meet the MPLS-TP OAM requirements specified in [IETF RFC 5860]. It also specifies the MPLSTP OAM packet formats@ syntax and semantics of MPLS-TP OAM packet fields. The OAM mechanisms described 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 described in this Recommendation are applicable in network scenarios@ as described in Annex A@ and 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 edition of this Recommendation. This Recommendation provides a representation of the MPLS-TP technology using the methodologies that have been used for other transport technologies [e.g.@ synchronous digital hierarchy (SDH)@ optical transport network (OTN) and Ethernet].1 1 This Recommendation is intended to be aligned with the IETF RFCs on MPLS referenced normatively by this Recommendation.
