Technical, Commerical and Regulatory Challenges of QoS provides a comprehensive examination of Internet QoS theory, standards, vendor implementation and network deployment from the practitioner's point of view, including extensive discussion of related economic and regulatory issues. Written in a technology-light way so that a variety of professionals and researchers in the information and networking industries can easily grasp the material. Includes case studies based on real-world experiences from industry. The author starts by discussing the economic, regulatory and technical challenges of the existing QoS model. Key coverage includes defining a clear business model for selling and buying QoS in relation to current and future direction of government regulation and QoS interoperability (or lack thereof) between carriers and networking devices. The author then demonstrates how to improve the current QoS model to create a clear selling point, less regulation uncertainty, and higher chance of deployment success. This includes discussion of QoS re-packaging to end-users; economic and regulatory benefits of the re-packaging; and the overall benefits of an improved technical approach. Finally, the author discusses the future evolution of QoS from an Internet philosophy perspective and lets the reader draw the conclusions. This book is the first QoS book to provide in depth coverage on the commercial and regulatory aspects of QoS, in addition to the technical aspect. From that, readers can grasp the commercial and regulatory issues of QoS and their implications on the overall QoS business model. This book is also the first QoS book to provide case studies of real world QoS deployments, contributed by the people who did the actual deployments. From that, readers can grasp the practical issues of QoS in real world. This book is also the first QoS book to cover both wireline QoS and wireless QoS. Readers can grasp the QoS issues in the wireless world. The book was reviewed and endorsed by a long list of prominent industrial and academic figures. Discusses QoS technology in relation to economic and regulatory issues Includes case studies based on real-world examples from industry practitioners Provides unique insight into how to improve the current QoS model to create a clear selling point, less regulatory uncertainty, and higher chance of deployment success

We revisit the last 35 years of history related to the design and specification of Quality of Service (QoS) on the Internet, in hopes of offering some clarity to the current debates around service differentiation. We describe the continual failure to get QoS capabilities deployed on the public Internet, including the technical challenges of the 1980s and 1990s, the market-oriented (business) challenges of the 1990s and 2000s, and recent regulatory challenges. In short, the engineering community successfully developed protocols and mechanisms to implement enhanced services (QoS), and a few individual service providers have deployed them internally or in trusted two-party scenarios. The long-standing failure has been to deploy this capability across the public Internet. We reflect on lessons learned from the history of this failure, the resulting tensions and risks, and their implications for the future of Internet infrastructure regulation. First, the continued failure of QoS over the last three decades derives from political and economic (business) obstacles as well as technical obstacles. The competitive nature of the industry, and a long history of anti-trust regulation (at least in the U.S.) conflicts with the need for competing providers to agree on protocols that require sharing operational data with each other to parameterize and verify committed service qualities. Second, QoS technology can yield benefits as well as harms, so policymaking should focus on harms rather than mechanisms. To assure the benefit to consumers, regulators may need to require transparency about the state of congestion and provisioning on networks using such mechanisms. Third, using QoE as the basis for any regulation will require research, tools and capabilities to measure, quantify, and characterize QoE, and developing metrics of service quality that better reflect our understanding of QoS and QoE for a range of applications. Finally, profound shifts in interconnection arrangements suggest a reshaping of the debate over QoS on the public Internet. Some access networks are interconnecting their private IP-based network platforms to support enhanced services, and using this interconnected platform to vertically integrate infrastructure and applications. Access networks are also connecting directly to large content providers to minimize the risk of performance impairments. These changes trigger new regulatory concerns over the fate of the public Internet, including capital investment incentives and gaps across different bodies of law. Barriers to the deployment of scalable interprovider QoS may be unsurmountable, but since any Internet of the future will face them, it is worth developing a systematic understanding to the challenge of enhanced services, and documenting successes and failures over the history of the Internet as carefully as possible.

Develop cost-effective, long-term solutions to your network traffic control problems. Even if you can find the money to do it, overengineering your network will not solve your traffic flow problems. As the authors of this groundbreaking guide clearly demonstrate, the best long-term solution to network congestion and bottlenecks can be found in a set of Quality of Service (QoS) architectures, policies, and technologies known as differentiated Classes of Service (CoS). Quality of Service is a valuable working resource for technical managers charged with solving the problem of how to handle the exploding volume of traffic on their companies' networks. The authors explore the roots of the current network traffic control crisis and they provide a realistic assessment of the gamut of standard, new, and emerging QoS/CoS technologies. They consider all crucial, design, cost, and support issues surrounding quality of service deployment for all types of networks, including intranets and multimedia networks. And they provide managers with a rational framework for finding the most cost-effective QoS/CoS solutions to their organizations' long-term networking goals. Key technical issues covered include: * Queuing disciplines, traffic shaping, and admission control techniques * Quality and differentiation hooks found in TCP/IP * Getting the most out of Frame Relay and ATM technologies * QoS/CoS techniques for dial-up services * Integrated Services Architecture and RSVP.

The current book provides a final report of activity performed by the COST 290 Action, ‘‘Traffic and QoS Management in Wireless Multimedia Networks,’’ which ran from March 10, 2004, until June 3, 2008. After an introduction to the COST framework and the Action’s survey time-frame and activities, the main part of the book addresses a number of technical issues, which are structured into several chapters. All those issues have been carefully investigated by the COST 290 community during the course of the project – the information presented in this book can be regarded as ultimate for each particular topic; every open research issue addressed in the book is described carefully, corresponding existing studies are analyzed and results achieved by the COST 290 community are presented and compared, and further research directions are defined and analyzed. Because the book covers a wide area of research addressing issues of modern wired and wireless networking at different layers, starting from the physical layer up to the application layer, it can be recommended to be used by researchers and students to obtain a comprehensive analysis on particular research topics including related areas, to obtain broad and ultimate referencing, and to be advised on current open issues. COST 290 is one of the Actions of the European COST Program. Founded in 1971, COST is an intergovernmental framework for European Cooperation in the field of Scientific and Technical Research, allowing the coordination of nationally funded research on a European level.

The transportation of multimedia over the network requires timely and errorless transmission much more strictly than other data. This had led to special protocols and to special treatment in multimedia applications (telephony, IP-TV, streaming) to overcome network issues. This book begins with an overview of the vast market combined with the user’s expectations. The base mechanisms of the audio/video coding (H.26x etc.) are explained to understand characteristics of the generated network traffic. Further chapters treat common specialized underlying IP network functions which cope with multimedia data in conjunction which special time adaption measures. Based on those standard functions these chapters can treat uniformly SIP, H.248, High-End IP-TV, Webcast, Signage etc. A special section is devoted to home networks which challenge high-end service delivery due to possibly unreliable management. The whole book treats concepts described in accessible IP-based standards and which are implemented broadly. The book is aimed at graduate students/practitioners with good basic knowledge in computer networking. It provides the reader with all concepts of currently used IP technologies of how to deliver multimedia efficiently to the end user.

The book presents a comprehensive view on Flow-Aware Networking. It starts with a brief overview of the known QoS architectures based on the concept of a flow. Then, the original FAN concept is presented, along with its variations proposed by the authors. The next chapter covers a very valuable feature of the FAN architecture, namely its ability to assure net neutrality. The chapters that follow will discuss, in detail, a variety of issues making the FAN concept implementable, including congestion control, fairness, resilience to failures, service differentiation and degradation. The final chapter presents the test implementation of the FAN router, including the environment used and performance tests. Chapters are supplemented with problems to solve, along with their solutions. The pedagogical character of the book is supported by a number of illustrative examples contained in most of the chapters. At the end of the book, a glossary of the key terms is included, along with a comprehensive bibliography. Flow-based traffic management is currently becoming a mainstream. There is plenty of Quality of Service (QoS) techniques based on flows. Software-Defined Networking with its dominant protocol OpenFlow also follows this trend. Flow-Aware Networking (FAN) is a promising QoS architecture. Information on FAN can be found in various research papers. It is, therefore highly scattered. This book gathers practically all relevant information regarding FAN and puts it together. Quality of Service assurance is one of the key challenges of today’s Internet. The existing approaches to provide QoS do not meet expectations of network operators, managers and users although numerous efforts in this area have been reported. One of the most promising concepts is the Flow-Aware Network (FAN). FAN can play a key role in assuring the net neutrality, smoothly combining interests of all the involved parties. The authors of the proposal have been involved in FAN research practically since its inception at the start of the 21st century. The book reports the wide experiences the authors accumulated in the subject area during the work on common FAN-related projects conducted with the team of James Roberts that proposed the original FAN concept as well as other leading research groups in Europe and the USA. One of the aims of the book is to accompany courses taught by the authors.
