This book provides a practical guide to flow-aware networking (FAN), one of the most promising new quality-of-service architectures for the Future Internet. The latest concepts are examined in detail, including coverage of approximate flow-aware networking. The scope and evolution of the debate on network neutrality is also discussed. Topics and features: provides a broad survey of flow-oriented approaches and solutions based on the concept of flows; presents a range of mechanisms for improving transmission performance of streaming flows under congestion; illustrates how problems caused by congestion may be solved in a multilayer environment, proposing new methods for enhancing transmission in wired-wireless FAN; analyzes aspects of fair transmission in FAN, reviewing algorithms that improve transmission of streaming flows during network failures; describes the implementation aspects of the cross-protect router; concludes each chapter with review questions, with answers provided at the end of the book.
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.
Shows how the networking-averse can succeed by working with the very traits that make them hate traditional networking Written by a proud introvert who is also an enthusiastic networker Includes field-tested tips and techniques for virtually any situation Are you the kind of person who would rather get a root canal than face a group of strangers? Does the phrase working a room make you want to retreat to yours? Does traditional networking advice seem like its in a foreign language? Devora Zack, an avowed introvert and a successful consultant who speaks to thousands of people every year, feels your pain. She found that most networking advice books assume that to succeed you have to become an outgoing, extraverted person. Or at least learn how to fake it. Not at all. There is another way. This book shatters stereotypes about people who dislike networking. Theyre not shy or misanthropic. Rather, they tend to be reflective - they think before they talk. They focus intensely on a few things rather than broadly on a lot of things. And they need time alone to recharge. Because theyve been told networking is all about small talk, big numbers and constant contact, they assume its not for them. But it is! Zack politely examines and then smashes to tiny fragments the dusty old rules of standard networking advice. She shows how the very traits that ordinarily make people networking-averse can be harnessed to forge an approach that is just as effective as more traditional approaches, if not better. And she applies it to all kinds of situations, not just formal networking events. After all, as she says, life is just one big networking opportunity - a notion readers can now embrace. Networking enables you to accomplish the things that are important to you. But you cant adopt a style that goes against who you are - and you dont have to. I have never met a person who did not benefit tremendously from learning how to network - on his or her own terms, Zack writes. You do not succeed by denying your natural temperament; you succeed by working with your strengths.
"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.

This book is an advanced explanation of the state-of-the art in Context-Aware Services. The authors describe and characterize this type of service as well as the specific service dimension that is, 'context'.
Network flow theory has been used across a number of disciplines, including theoretical computer science, operations research, and discrete math, to model not only problems in the transportation of goods and information, but also a wide range of applications from image segmentation problems in computer vision to deciding when a baseball team has been eliminated from contention. This graduate text and reference presents a succinct, unified view of a wide variety of efficient combinatorial algorithms for network flow problems, including many results not found in other books. It covers maximum flows, minimum-cost flows, generalized flows, multicommodity flows, and global minimum cuts and also presents recent work on computing electrical flows along with recent applications of these flows to classical problems in network flow theory.
