“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.

 

Coverage includes 

·    An in-depth introduction to next-generation triple-play services: components, integration, and business connectivity

·    Triple-play backbone design: MPLS, Layer 3 VPNs, and Broadband Network Gateways (BNGs)/Broadband Remote Access Servers (B-RAS)

·    Protocols and strategies for integrating BNGs into robust triple-play networks

·    Triple-play access network design: DSLAM architectures, aggregation networks, transport, and Layer 2 tunneling

·    VLAN-per-customer versus service-per-VLAN architectures: advantages and disadvantages

·    PPP or DHCP: choosing the right access protocol

·    Issues associated with operating in wholesale, unbundled environments

·    IP addressing and subscriber session management

·    Broadband network security, including Denial of Service attacks and VoIP privacy

·    The future of wireless broadband: IMS, SIP, and non-SIP based fixed mobile convergence and wireless video

Broadband networks, such as asynchronous transfer mode (ATM), frame relay, and leased lines, allow us to easily access multimedia services (data, voice, and video) in one package. Exploring why broadband networks are important in modern-day telecommunications, Introduction to Broadband Communication Systems covers the concepts and components of both standard and emerging broadband communication network systems.

After introducing the fundamental concepts of broadband communication systems, the book discusses Internet-based networks, such as intranets and extranets. It then addresses the networking technologies of X.25 and frame relay, fiber channels, a synchronous optical network (SONET), a virtual private network (VPN), an integrated service digital network (ISDN), broadband ISDN (B-ISDN), and ATM. The authors also cover access networks, including digital subscriber lines (DSL), cable modems, and passive optical networks, as well as explore wireless networks, such as wireless data services, personal communications services (PCS), and satellite communications. The book concludes with chapters on network management, network security, and network testing, fault tolerance, and analysis.

With up-to-date, detailed information on the state-of-the-art technology in broadband communication systems, this resource illustrates how some networks have the potential of eventually replacing traditional dial-up Internet. Requiring only a general knowledge of communication systems theory, the text is suitable for a one- or two-semester course for advanced undergraduate and beginning graduate students in engineering as well as for short seminars on broadband communication systems.
