Network distribution capacity and content-pipe gap

Abstract— The growth of video content and diversification of content-sharing methods in the Internet lead to an exciting range of new problems in networking, communications, and signal processing. They range from fundamental theory and analytic models to practical design and industry deployment. This informal note briefly discusses some of the opportunities arising out of the “content-pipe” gap and presents some of the fundamental problems in distributing content over a network. I. CONTENT-PIPE GAP Networks are increasingly used for sharing content, especially video content, both copyrighted and usergenerated ones. They shake many basic assumptions on how networks should be designed and used. For example, the asymmetry between uplink and downlink data rates is no longer appropriate, the “horizontal decomposition” into access-metro-core networks may be inefficient if both the content producers and consumers reside in the same access network, and the “vertical decompositio...
