"Network professionals who are looking to deploy triple-play service provider networks will find this book a useful tool."
-Michael Newbery, IP Architect, TelstraClear Limited
"This book provides a wealth of information on current and future broadband architectures, services, and deployments. It will serve both experienced technical experts needing a comprehensive reference, as well as those needing a concise explanation of broadband access architectures and multi-play services."
-Sanjay Wadhwa, Product Line Manager, IP Edge Products, Juniper Networks
"This book is a thorough guide for anyone involved with triple-play networks. Its multivendor approach and references to the latest standards from the DSL Forum and the IETF makes it a must-have for anyone involved in broadband access networks."
-Andrea Lasagna, Data & Video Services Manager, FASTWEB
Service providers are increasingly focused on delivering triple-play bundles that incorporate Internet, video, and VoIP services-as well as multi-play bundles containing even more advanced services. Broadband Network Architectures is the first comprehensive guide to designing, implementing, and managing the networks that make triple-play services possible.
Hellberg, Greene, and Boyes present their field-tested industry best practices and objectively evaluate the tradeoffs associated with key up-front architectural decisions that balance the complexities of bundled services and sophisticated traffic policies. Broadband Network Architectures not only documents what is possible on this rapidly changing field of networking, but it also details how to divide Internet access into these more sophisticated services with specialized Quality of Service handling.
