Content Distribution in AT&T: an Architecture and Research Overview

Fred Douglis
AT&T Labs--Research

About the talk:

Caching and replication, collectively referred to as content distribution, are rapidly growing in importance in the Internet. On the web hosting side, the marketplace has already passed $1B and could reach $11B by 2002. AT&T aspires to be one of the largest web hosting providers in addition to already being one of the largest Internet service providers. This talk describes the Content Distribution component of the AT&T Internet Architecture. It surveys the existing commercial landscape and discusses some of the architectural alternatives. Then it discusses several related research projects within AT&T, such as delta-encoding, prefetching, connection management, and proxy performance.
