IP Quality of Service

The complete resource for understanding and deploying IP quality of service for Cisco networks

Learn to deliver and deploy IP QoS and MPLS-based traffic engineering by understanding:

* QoS fundamentals and the need for IP QoS
* The Differentiated Services QoS architecture and its enabling QoS functionality
* The Integrated Services QoS model and its enabling QoS functions
* ATM, Frame Relay, and IEEE 802.1p/802.1Q QoS technologies and how they work with IP QoS
* MPLS and MPLS VPN QoS and how they work with IP QoS
* MPLS traffic engineering
* Routing policies, general IP QoS functions, and other miscellaneous QoS information

Quality-of-service (QoS) technologies provide networks with greater reliability in delivering applications, as well as control over access, delay, loss, content quality, and bandwidth. IP QoS functions are crucial in today’s scalable IP networks. These networks are designed to deliver reliable and differentiated Internet services by enabling network operators to control network resources and use. Network planners, designers, and engineers need a thorough understanding of QoS concepts and features to enable their networks to run at maximum efficiency and to deliver the new generation of time-critical multimedia and voice applications.

* Learn about classification and rewrite capabilities and queue scheduling on the Cisco Catalyst 5000
* Implement ACLs, ACPs, ACEs, and low-latency queuing on the Cisco Catalyst 2950 and 3550 Family of Switches
* Understand classification, policying, and scheduling capabilities of the Catalyst 4000 and 4500 IOS Family of Switches
* Configure QoS in both Hybrid and Native mode on the Catalyst 6500 Family of Switches

* Understand how to apply QoS in campus network designs by examining end-to-end case studies

Quality of service (QoS) is the set of techniques designed to manage network resources. QoS refers to the capability of a network to provide better service to selected network traffic over various LAN and WAN technologies. The primary goal of QoS is to provide flow priority, including dedicated bandwidth, controlled jitter and latency (required by some interactive and delay-sensitive traffic), and improved loss characteristics.

End-to-End QoS Network Design: Quality of Service in LANs, WANs, and VPNs

Best-practice QoS designs for protecting voice, video, and critical data while mitigating network denial-of-service attacks

* Understand the service-level requirements of voice, video, and data applications
* Examine strategic QoS best practices, including Scavenger-class QoS tactics for DoS/worm mitigation
* Learn about QoS tools and the various interdependencies and caveats of these tools that can impact design considerations
* Learn how to protect voice, video, and data traffic using various QoS mechanisms
* Evaluate design recommendations for protecting voice, video, and multiple classes of data while mitigating DoS/worm attacks for the following network infrastructure architectures: campus LAN, private WAN, MPLS VPN, and IPSec VPN

Quality of Service (QoS) has already proven itself as the enabling technology for the convergence of voice, video, and data networks. As business needs evolve, so do the demands for QoS. The need to protect critical applications via QoS mechanisms in business networks has escalated over the past few years, primarily due to the increased frequency and sophistication of denial-of-service (DoS) and worm attacks.

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.

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. The book provides a thorough explanation of the technology behind MPLS QoS and related technologies, including the different design options you can use to build an 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. You’ll learn technology, configuration, and operational details, including the essentials facts about the behavior and configuration of the rich MPLS QoS and related MPLS TE functionality. To get the most out of this book, you should have a basic understanding of both IP and MPLS, including the basics of IP addressing and routing and the basics of MPLS forwarding.
