AIMD and CCN: past and novel acronyms working together in the Future Internet

Wed, 09/26/2012 - 22:18 by Damien Saucez

Abstract

Content-centric networking is a new paradigm to better handle contents in the future Internet. Routing is done on a hop-by-hop basis by content names and routers are given the possibility to cache contents for a more efficient band- width utilization. This new paradigm poses several challenges, among them the congestion control problem which we explore in this paper by supposing that CCN networks will deploy similar congestion control than in today TCP/IP. We analytically evaluate the way bandwidth is shared with CCN and we compare the performance of downloads to what users get today. We consider different factors such as the way CCN routers are deployed, the popularity of contents and the bandwidth of links. We make several observations and suggestions, most importantly that a CCN congestion control like TCP penalizes non-popular contents because of their low hit ratio and hence their longer network delay. A proper congestion control should in somehow compensate the decrease of network delay CCN caching provides for popular contents.
