A comprehensive guide to implementing QoS in IP / MPLS network using Cisco IOS and Cisco IOS XR Software Understand IP QoS architectures and how they apply to MPLS detailed look at traffic management using policing, shaping, scheduling, and active queue management Study Cisco QoS behavioral model and the interface of the modular QoS command-line (MQC) Learn the operation of MPLS TE with DiffServ extensions and application as an alternative to traffic-protection Search multiple configurations and examples that illustrate the implementation of verification MPLS TE, DS-TE, and FRR Review the different designs, ranging from the backbone of the best-effort to the most elaborate scenarios combining DiffServ, DS- TE, and FRR Quality of Service (QoS) plays an important role in the implementation of IP and MPLS networks today. QoS for IP / MPLS Networks is a practical guide that will help you facilitate the design, deployment, and operation of QoS using Cisco IOS Software and Cisco IOS XR Software. This book provides a thorough explanation of the technology behind MPLS QoS and related technologies, including different design options you can use to build MPLS network with strict performance requirements. This book discusses MPLS Traffic Engineering (MPLS TE) as a tool to complement MPLS QoS and enhance the performance characteristics of the network.
