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.
