{P2PPerf}: a framework for simulating and optimizing peer-to-peer distributed computing applications

International audiencePeer-to-Peer architectures are more and more studied by distributed computing community. Indeed, this type of architecture makes possible to inherit few properties, in particular the absence of centralized topology, fault-tolerance and dynamic reorganization of the network. However, the complexity of these networks is increased and the acceleration of the distributed applications is not ensured. That's why it is necessary to predict the performances as soon as possible in design and development phases, to bypass bottlenecks and correct program blocks which slow down the execution time. In this context, we propose P2PPerf: a simulation tool of which objective is to predict performances and execution times of a distributed application before its finalization. P2PPerf has been tested on JNGI: a P2P distributed computing application using the JXTA platfor
