Influence of Replication on Availability within P2P Systems
Timo Warns, Wilhelm Hasselbring, Mark Roantree · 2005
Abstract. An increasing number of digital library management systems is developed following P2P architectures to overcome the bottlenecks of client/server architectures. Usually, the participating peers are less dependable than traditional servers. Hence, a P2P system needs to deal with failures of single peers to avoid overall system failures. Replication is a means to improve availability of resources. We empirically investigate the influence of replication techniques on availability by simulations. We focus on voting-based replication control strategies which offer one-copyserializability in the context of our XPeer architecture. 1
