Summary:
|
Recommendation ITU-T G.8113.1/Y.1372.1 specifies mechanisms for user-plane operations, administration and maintenance (OAM) in multi-protocol label switching transport profile (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 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.
