13.1. INTRODUCTION

In the previous chapters we have seen how MPLS is used as a key component for converging multiple services on to the same physical infrastructure. As service providers obtain more of their revenue from MPLS-enabled applications and as the traffic carried requires stricter SLAs, the ability to manage both the MPLS infrastructure and the services running on top of it efficiently becomes more important.

In this chapter we will take a look at some of the unique aspects of managing MPLS networks and services. Some of the topics covered are fault detection and the emerging mechanisms for detecting data plane failures, provisioning challenges and tools for gaining visibility into the network.
