Information-Centric Multiaccess P2P Networks

This paper explores the performance benefits of an information-centric network which capitalizes on overlapping multiaccess for content distribution. We present our architecture which uses an enhanced BitTorrent protocol, supports multiple network accesses simultaneously, and localizes information retrieval. We employ simulation to show the gains, on one hand, in individual node performance and, and on the other, in reduced load on the inter-operator traffic. Our simulation results indicate that download durations can be reduced, on median, by 33%. More importantly, upload throughput can increase significantly by 63%, on median. Finally, we show that our system can limit inter-domain traffic through hierarchical information-centric name resolution. The evidence we present indicates that an information-centric approach can be beneficial for both end users retrieving content such as files or video streaming, and for network opera-tors.
