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

An analysis of the failure of U.S. broadband policy to solve the rural–urban digital divide, with a proposal for a new national rural broadband plan. As much of daily life migrates online, broadband—high-speed internet connectivity—has become a necessity. The widespread lack of broadband in rural America has created a stark urban–rural digital divide. In Farm Fresh Broadband, Christopher Ali analyzes the promise and the failure of national rural broadband policy in the United States and proposes a new national broadband plan. He examines how broadband policies are enacted and implemented, explores business models for broadband providers, surveys the technologies of rural broadband, and offers case studies of broadband use in the rural Midwest. Ali argues that rural broadband policy is both broken and incomplete: broken because it lacks coordinated federal leadership and incomplete because it fails to recognize the important roles of communities, cooperatives, and local providers in broadband access. For example, existing policies favor large telecommunication companies, crowding out smaller, nimbler providers. Lack of competition drives prices up—rural broadband can cost 37 percent more than urban broadband. The federal government subsidizes rural broadband by approximately $6 billion. Where does the money go? Ali proposes democratizing policy architecture for rural broadband, modeling it after the wiring of rural America for electricity and telephony. Subsidies should be equalized, not just going to big companies. The result would be a multistakeholder system, guided by thoughtful public policy and funded by public and private support.

Broadband Satellite Communications for Internet Access is a systems engineering methodology for satellite communication networks. It discusses the implementation of Internet applications that involve network design issues usually addressed in standard organizations. Various protocols for IP- and ATM-based networks are examined and a comparative performance evaluation of different alternatives is described. This methodology can be applied to similar evaluations over any other transport medium.

Access to the Internet is an increasing problem in many areas of the world. As the popularity and usefulness of the Internet increases on a daily basis, lack of access to the technology is putting many groups at a disadvantage in terms of better education, better jobs and even in terms of higher levels of civic participation. However, creating a network infrastructure to serve outlying communities and sectors of the population is not straight-forward. This book brings together all the aspects of the problem – technical, regulatory and economic - into one volume to provide a comprehensive resource. It describes the latest technological advances that allow cost-effective network infrastructures to be built, and places them in the context of the applications and services that the infrastructure will deliver. A section on business models and case studies from North American and Europe demonstrate that the solutions are economically and practically viable. This book is essential for anyone looking to gain an understanding of the issues and technology surrounding the access debate. It will be of particular relevance to network engineers/designers/planners at the incumbent operator companies charged with delivering broadband access to as yet unconnected regions. Governments and regulatory bodies will also find this a useful guide to the problems that they may face.

In the Committee's report on broadband services it considers that the UK and Welsh Governments must work together and use all means available to bring broadband services in Wales up to speed with the rest of the UK, and eradicate broadband "slow spots" and "notspots" as a matter of urgency. Both Governments should consider promoting mobile and satellite technologies, particularly in remote areas of Wales in order to deliver this and not rely solely on rolling out fibre optic cabling. The availability of broadband has been consistently lower in Wales than the rest of the UK and although that gap has narrowed in recent years latest figures show the gap is widening again. The existence of notspots an slowspots has hindered existing businesses and deterred new businesses from choosing to locate to Wales - to the cost of the local economy.The Welsh Government's target is a commitment to provide all Welsh businesses with access to next-generation broadband by "the middle of 2016". The Committee also says that both Governments must ensure that the roll-out of superfast broadband is not achieved at the expense of delivering a good broadband service for all. The Committee recommends that Ofcom undertake a study to evaluate whether satellite broadband should be supported more vigorously in Wales; the delayed Spectrum auction, now planned for 2013, must ensure that 4G mobile services are available to at least 98% of people in Wales; and Ofcom must continue its efforts to open up access to infrastructure in Wales. BT's market power must be regulated effectively to ensure efficient operation of the market.

If you loved Hidden Figures or The Rise of the Rocket Girls, you'll love Claire Evans' breakthrough book on the women who brought you the internet--written out of history, until now. "This is a radically important, timely work," says Miranda July, filmmaker and author of The First Bad Man. The history of technology you probably know is one of men and machines, garages and riches, alpha nerds and brogrammers--but from Ada Lovelace, who wrote the first computer program in the Victorian Age, to the cyberpunk Web designers of the 1990s, female visionaries have always been at the vanguard of technology and innovation. In fact, women turn up at the very beginning of every important wave in technology. They may have been hidden in plain sight, their inventions and contributions touching our lives in ways we don't even realize, but they have always been part of the story. VICE reporter and YACHT lead singer Claire L. Evans finally gives these unsung female heroes their due with her insightful social history of the Broad Band, the women who made the internet what it is today. Seek inspiration from Grace Hopper, the tenacious mathematician who democratized computing by leading the charge for machine-independent programming languages after World War II. Meet Elizabeth "Jake" Feinler, the one-woman Google who kept the earliest version of the Internet online, and Stacy Horn, who ran one of the first-ever social networks on a shoestring out of her New York City apartment in the 1980s. Join the ranks of the pioneers who defied social convention to become database poets, information-wranglers, hypertext dreamers, and glass ceiling-shattering dot com-era entrepreneurs. This inspiring call to action shines a light on the bright minds whom history forgot, and shows us how they will continue to shape our world in ways we can no longer ignore. Welcome to the Broad Band. You're next.
