From the basics to the most advanced quality-of-service (QoS) concepts, this book aims to offer professionals an in-depth understanding of the latest technical issues raised by the emergence of new types of internet services. It provides end-to-end QoS guidance for real-time multimedia communications over the internet, and shows where and when it is preferable to use certain techniques for QoS support in networks and internet traffic. This practical resource discusses key standards and protocols, and features numerous examples and graphs that illustrate important concepts. It includes case studies that show how to build networks supporting Quality of Service. This book serves as a text for: software developers and researchers; network engineers, designers and managers; and graduate students in advanced QoS courses and related courses.
