RFC 5860 OAM Requirements for MPLS-TP May 2010
1. Introduction
In the context of MPLS Transport Profile (MPLS-TP, see [9] and [1]),
the rationales for Operations, Administration, and Maintenance (OAM)
are twofold as it can serve:
o as a network-oriented functionality, used by a transport network
operator to monitor his network infrastructure and to implement
