Preface

This book provides design considerations and guidelines for implementing Quality of Service (QoS) within emerging 4G networks. QoS best practices are recommended by the contributing authors, and new innovative concepts, solutions, and research results are presented in depth.

The editors originally came together about four years ago as the core team of the Application Architecture Task Group of the WiMAX Forum (which later became the Application Working Group) to facilitate various applications over the mobile broadband access networks. We pursued development of best practices and guidelines to encourage the industry towards unified solutions for better interoperability and performance. Given that there was not a good reference that looked at the performance requirements of the existing and emerging voice, video and data applications in the context of the architectural constraints of the mobile broadband networks, we decided to pull together the present book to fill that void.

A recurring subtext in this book is that the wired and wireless networks have a key difference in how the QoS required for different applications can be supported over them. Although a number of intelligent solutions have been developed to manage QoS over the wired networks, because of the commoditization of the underlying resources, we find that more often than not the service providers resort to “throwing bandwidth” at the QoS issues for resolving them. Wireless networks cannot afford such a luxury. These networks not only have tight limits on how much bandwidth they can offer due to the spectrum scarcity, they need to manage interference and congestion dynamics in presence of mobility. This accompanied with the explosion of new applications over the mobile broadband networks (e.g., plethora of new Blackberry and iPhone applications) has made it critical that efficient QoS management solutions are implemented to ensure widespread success of the mobile broadband networks. The ongoing debate on net neutrality necessitates that the QoS management solutions continue to provide open access while supporting and encouraging adoption of new QoS intensive services.
