Leveraging the SCION Internet Architecture to Accelerate File Transfers over BitTorrent
Marten Gartner, Thorben Kr\"uger, David Hausheer

TL;DR
This paper introduces a novel approach using the SCION Internet architecture to enhance BitTorrent file transfers by enabling multipath communication and intelligent path selection, resulting in significant throughput improvements.
Contribution
It presents a new method integrating SCION with BitTorrent to optimize data flow through multipath and disjoint path selection, outperforming traditional BGP-based methods.
Findings
48% increase in goodput over BGP
33% increase in goodput over BGP-M
Effective traffic flow improvement with few outgoing connections
Abstract
As the needs of Internet users and applications significantly changed over the last decade, inter-domain routing became more important to fulfill these needs. The ways how data flows over the Internet are still completely in the hand of network operators, who optimize traffic according to their own, local view of the network. We observe two potential limitations from this: Optimizing according to the local view may a) result in unused capacities in the global network and b) not meet the actual needs of users and applications. To identify and overcome these limitations, we present our BitTorrent over SCION approach, which enables multipath communication and intelligent path selection for endhosts in global torrent networks. We compare our implementation against BitTorrent over BGP and BGP-M in a small-scale Internet topology, observing an increase in goodput of 48% through multipathing…
