A comprehensive guide to implementing QoS in IP/MPLS networks using Cisco IOS and Cisco IOS XR SoftwareUnderstand IP QoS architectures and how they apply to MPLS Take a detailed look at traffic management using policing, shaping, scheduling, and active queue managementStudy 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 alternativeFind 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.
