Abstract

Gnutella’s notoriously poor scaling led some to propose distributed hash table solutions to the wide-area file search problem. Contrary to that trend, in this paper, we advocate retaining Gnutella’s simplicity while proposing GToS, a Gnutella-like Topology- oriented Search protocol for high-performance distributed file sharing, by examining the role of overlay topology on system performance improvement. Building upon prior research [10], we propose several modifications as enhancements and then refine these novel ideas, with the aim of trying to remedy the “mismatch” between the logical overlay topology and its projection on the underlying network. We test our design through extensive simulations and the results show a significant system performance improvement.
