Abstract

Despite the leaps and bounds made by the P2P research field in the last few years, the benefit of this innovation has been constrained to a few areas; search and file-sharing and storage to name a few. In particular, this innovation has had little significant impact in the field of distributed computing. There are several obstacles to be overcome in the development of any distributed computer, most notably: scalability, fault tolerance, security and load balancing. The difficulty of these is compounded in the dynamic, decentralized environment which characterizes the P2P arena. This paper presents a method of recovering from faults which exploits the distributed hash table functionality provided by modern overlay networks. Its effectiveness is evaluated experimentally using a proof of concept P2P distributed computer. It is hoped that by providing a solution to one of the obstacles, global, decentralized, dependable distributed computers will be one step closer to reality.
