MPLS-TP OAM introduction

Multiprotocol Label Switching Protocol Transport Profile (MPLS-TP) is a transport technique that integrates the MPLS packet switching and conventional transport techniques. An MPLS-TP network can function as a future-proof bearer network that replaces the existing transport networks. Working at MPLS-TP client layer and server layer, MPLS-TP operation, administration and maintenance (OAM) can effectively detect, identify, and locate faults at the client layer and quickly switch traffic when links or nodes become defective. OAM is an important means to reduce network maintenance expenditure. MPLS-TP OAM implements O&M at the MPLS-TP layer.
