¿µ¹®³»¿ë¿ä¾à The OAM mechanisms defined in this standard assume common forwarding of the MPLS-TP user packets and MPLS-TP OAM packets. In transport networks using co-routed bidirectional point-to-point connections, the OAM return path is always in band. This standard provides a representation of the MPLS-TP technology using the methodologies that have been used for other transport technologies (e.g. SDH, OTN and Ethernet). This standard provides a description of the MPLS-TP functional components, OAM functions, OAM PDU Formats, MPLS-TP OAM Procedures defined by the IETF. Amendment 1 adds material related to client signal fail handling.
