A comprehensive guide to implementing QoS in IP/MPLS networks using Cisco IOS and Cisco IOS XR Software
Understand IP QoS architectures and how they apply to MPLS 
Take a detailed look at traffic management using policing, shaping, scheduling, and active queue management 
Study Cisco QoS behavioral model and the modular QoS command-line interface (MQC) 
Learn the operation of MPLS TE with its DiffServ extensions and applicability as a traffic-protection alternative 
Find multiple configuration and verification examples illustrating the implementation of MPLS TE, DS-TE, and FRR 
Review the different designs, ranging from a best-effort backbone to the most elaborate scenarios combining DiffServ, DS-TE, and FRR 
Quality of service (QoS) plays a key role in the implementation of IP and MPLS networks today. However, QoS can be one of the most complex aspects of networking. The industry efforts to achieve convergence have generated a need for increased levels of traffic differentiation. Today's networks need to meet an array of QoS requirements to support distinct applications (such as voice, video, and data) and multiple network services (such as IP, Ethernet, and ATM) on a single converged, multiservice network. QoS has therefore has become an integral part of network design, implementation, and operation.
