A practical, service-oriented guide to large-scale ADSL implementation.
From service architecture to applications, standards to business case, Implementing ADSL delivers a complete, up-to-date analysis of what it takes to deploy ADSL. Written by a leading authority in the field, this book will be equally valuable for implementers and decision-makers in both service provider and enterprise IT organizations.
The author begins with a detailed look at the business drivers and financial models associated with ADSL implementation. Learn how to estimate ADSL service demand, revenue, capital, and ongoing expenses over the short and long-term; then review the current status of ADSL, G.Lite, and other xDSL technologies, cable modems, and other alternatives.
Next, Ginsburg introduces the ADSL service architecture, outlining an end-to-end service model from the physical layer to the network layer, and addressing crucial issues such as Quality of Service (QoS), security, and IP multicasting. Understand ADSL's physical infrastructure, including splitters and other premises equipment; DSLAMs and other central office equipment; aggregation, access, and core networks; digital loop carriers; gateways; caching solutions; and other key elements.
The author also reviews a wide range of ADSL services, including end-to-end ATM virtual circuits, PPP connections, bridging, routing, voice, video, and portals. You'll find seven detailed implementation scenarios, complete with diagrams and configuration listings based on actual deployments:
- Residential and corporate Internet access
- Portals and media distribution
- Internet wholesaling
- Corporate intranets and extranets
- Voice over IP
- Video streaming
Whether you are a network manager, architect, administrator, or engineer, Implementing ADSL brings together crucial information and insight for making the best possible decisions about today's most important access technology.
David Ginsburg is currently vice president of Marketing and Product Management for Allegro Networks, a Silicon Valley startup that is building the first multi-router system. Prior to joining Allegro, he was a vice president of Marketing at Nortel Networks. He went to Nortel via its acquisition of Shasta Networks, where he was a founding member of Shasta's marketing team that defined the industry's first broadband-services strategy. Before joining Shasta, Dave was with Cisco Systems as product manager for their DSL aggregator platform. Earlier roles at Cisco included WAN and LAN consulting engineering for key customers, at which time he was responsible for LAN switching, as well as ATM standardization and deployment. Dave is the author of two other books in the field of networking, both of which are available from Addison-Wesley.
