1.1 MPLS OAM Overview
Operation, administration and maintenance (OAM) is a tool designed for monitoring
and troubleshooting network problems. It provides an effective way of reducing network
maintenance costs. MPLS OAM is intended for the operation, administration and
maintenance on the MPLS layer.
1.1.1 MPLS OAM Background
MPLS supports multiple Layer 2 and Layer 3 protocols like IP, ATM, and Ethernet. To
enable the following features on the user plane of MPLS, MPLS needs to provide an
OAM mechanism fully independent of any upper layer or lower layer:
z
LSP connectivity.
z
Protection switching so that services can be provided in compliance with the
service level agreements (SLAs) signed with customers in the presence of link
defects (or failures).
With this MPLS OAM mechanism employed, you can effectively pinpoint defects in an
MPLS network, report defects and take corresponding measures, and provide a
triggering mechanism for protection switching in case of failures.

Recommendation Y.1710.
