Implementing Quality of Service Over Cisco MPLS VPNs

Chapter Description

This chapter covers the requirements for supporting the converged world of Multiprotocol Label Switching (MPLS) VPNs and how this maps to QoS policy applicable in the enterprise. The aim is to provide a deployable set of policies that the enterprise can use as guidelines. You'll also see how to address these policies to the service provider. Specifically, the QoS needs of Acme, Inc. are addressed in the case study.
