From the basics to the most advanced quality of service (QoS) concepts, this all encompassing, first-of-its-kind book offers an in-depth understanding of the latest technical issues raised by the emergence of new types, classes and qualities of Internet services. The book provides end-to-end QoS guidance for real time multimedia communications over the Internet. It offers you a multiplicity of hands-on examples and simulation script support, and shows you where and when it is preferable to use these techniques for QoS support in networks and Internet traffic with widely varying characteristics and demand profiles.This practical resource discusses key standards and protocols, including real-time transport, resource reservation, and integrated and differentiated service models, policy based management, and mobile/wireless QoS. The book features numerous examples, simulation results and graphs that illustrate important concepts, and pseudo codes are used to explain algorithms. Case studies, basedon freely available Linux/FreeBSD systems, are presented to show you how to build networks supporting Quality of Service. Online support material including presentation foils, lab exercises and additional exercises are available to text adoptors.

Guaranteeing performance and prioritizing data across the Internet may seem nearly impossible because of an increasing number of variables that can affect and undermine service. But if you're involved in developing and implementing streaming video or voice, or other time-sensitive Internet applications, you understand exactly what's at stake in establishing Quality of Service (QoS) and recognize the benefits it will bring to your company. What you need is a reliable guide to the latest QoS techniques that addresses the Internet's special challenges. Internet QoS is it-the first book to dig deep into the issues that affect your ability to provide performance and prioritization guarantees to your customers and users! This book gives a comprehensive view of key technologies and discusses various analytical techniques to help you get the most out of network resources as you strive to make, and adhere to, meaningful QoS guarantees.* Includes valuable insights from a Bell Labs engineer with 14 years of experience in data networking and Internet protocol design.* Details the enhancements to current Internet architectures and discusses new mechanisms and network management capabilities that QoS will require. * Focuses on the four main areas of Internet QoS: integrated services, differentiated services, MPLS (Multiprotocol Label Switching), and traffic engineering.

Service and network providers must be able to satisfy the demands for new services, improve the quality of service, reduce the cost of network service operations and maintenance, control performance and adapt to user demands. These challenges are so important for the future of our communication environment that it is essential to investigate different approaches for controlling and optimizing network resources. Network Control and Engineering for QoS, Security and Mobility II addresses the problem of network control and engineering with a focus on control of quality of service, management of security, and supervision of mobility. New trends in these different fields are also investigated. This volume contains the proceedings of the Second International Conference on NETwork CONtrol and Engineering (NETCON) for Quality of Service, Security and Mobility, which convened in Oman in October 2003. The conference was sponsored by the International Federation for Information Processing (IFIP) and organized by IFIP's Working Groups 6.2 on Network and Internetwork Architecture, 6.6 on Network Management, and 6.7 on Smart Networks.

This book describes, analyzes, and recommends traffic engineering (TE) and quality of service (QoS) optimization methods for integrated voice/data dynamic routing networks. These functions control a network's response to traffic demands and other stimuli, such as link failures or node failures. TE and QoS optimization is concerned with measurement, modeling, characterization, and control of network traffic, and the application of techniques to achieve specific performance objectives. The scope of the analysis and recommendations include dimensioning, call/flow and connection routing, QoS resource management, routing table management, dynamic transport routing, and operational requirements. Case studies are included which provide the reader with a concrete way into the technical details and highlight why and how to use the techniques described in the book. - Includes Case Studies of MPLS and GMPLS Network Optimization - Presents state-of-the-art traffic engineering and quality of service optimization methods and illustrates the tradeoffs between the various methods discussed - Contains practical Case Studies based on large-scale service provider implementations and architecture plans - Written by a highly respected and well known active expert in traffic engineering and quality of service

Written by two experts in the field who deal with QOS predicaments every day and now in this 2nd edition give special attention to the realm of Data Centers, QoS Enabled Networks: Tools and Foundations, 2nd Edition provides a lucid understanding of modern QOS theory mechanisms in packet networks and how to apply them in practice. This book is focuses on the tools and foundations of QoS providing the knowledge to understand what benefits QOS offers and what can be built on top of it.

"A critical guide through the tangled thicket of hype, assumptions, and facts about Quality of Service in IP Networks." - Scott Bradner, Senior Consultant at Harvard and Transport Area Director, IETF The next wave of Internet services will include voice and video as well as data. Supporting this will be the next generation of multiservice network platforms. This technology guide provides a comprehensive examination of the tools used to construct multiservice Internet networks, and provides up-to-the-minute solutions that deliver accurate services. Detailing every part of this important topic, this book covers the latest in standards work, Quality of Service architectures, detailed evaluation of performance-tuning tools, and design guidelines for achieving optimum performance from Internet networks. With this book, you'll gain an unprecedented look at the key issues that arise when engineering Internet networks to deliver defined levels of performance and learn how to fully utilize the wide array of service performance tools that are available in current Internet networks. Networking Council Books put technology in perspective or decision-makers who need an implementation strategy, a vendor and outsourcing strategy, and a product and design strategy.
