Abstract
While the current generation of peer-to-peer networks share predominantly static files, future peerto -peer networks will support sharing of files that are modified frequently by their users. In this paper, we present techniques to maintain temporal consistency of replicated files in a peer-to-peer network. We consider the Gnutella network and present techniques for maintaining consistency even when peers containing replicated files dynamically join and leave the network. We present extensions to the Gnutella protocol to incorporate our consistency techniques and implement them into a GtkGnutella prototype. An experimental evaluation of our techniques shows that: (i) a push-based approach achieves near-perfect fidelity in a stable P2P network, (ii) a hybrid approach based on push and pull achieves high fidelity in highly dynamic P2P networks and (iii) the run-time overheads of our techniques are small, making them a practical choice for P2P networks.
