Understanding churn in P2P
systems
Sponsor: NSF
Abstract
Peer-to-peer (P2P)
systems have recently evolved into complex, self-organizing entities that
provide a scalable, efficient, and decentralized platform for many Internet
applications. To support and continue expanding this important field, this
project develops fundamental analytical and experimental understanding of P2P
networks under user churn, which is a term describing dynamic behavior of P2P
systems in which arrivals and departures are not synchronized. This work builds
upon a synergy of analytical modeling of P2P dynamics and experimental sampling
of churn in real networks.
