On Blind Mice and the Elephant -- Understanding the Network Impact of a Large Distributed System
News
- 11/29/2011: AS topology made available.
Motivation and approach
A thorough understanding of the network impact of emerging large-scale distributed systems -- where traffic flows and what it costs -- must encompass users' behavior, the traffic they generate and the topology over which that traffic flows. In the case of BitTorrent, however, previous studies have been limited by narrow perspectives that restrict such analysis.
This work studies a comprehensive view of BitTorrent, using data from a representative set of 500,000 users sampled over a two year period, located in 169 countries and 3,150 networks.
We use public BGP data and the AS-level paths seen in traceroutes between BitTorrent users to infer the relationships between ASes, following the approach in our "Sidewalk Ends" work. This dataset, generated from data collected between March and May 2010, is available at the bottom of this page.
