About the Book

In an industry faced with increasing commoditization and competition, ISPs and Telcos are seeking new opportunities to deploy high-value services at the edge of the Internet. This timely book shows them how, focusing on the real-world implementation issues they'll face, and on the IP Services Switch (IPSS): breakthrough technology which is transforming how edge applications are delivered. The book begins with an overview of the service provider landscape, and the powerful opportunities for profit and differentiation associated with edge services. The authors compare today's leading technologies, including, cable, wireless, L2TP, IPSec, and MPLS; then introduce the technologies behind today's advanced networking, voice, and video service offerings. Coverage includes: IPSS implementation; traffic management; deployments; security and IP-VPN applications; content networking; and more. The book concludes with several real-world deployments and their business cases. For all ISPs, Telcos, CLECs, technical consultants, IT managers, and equipment vendors interested in deploying services at the edge of the Internet.
