چکیده

This paper presents details on the design and implementation of a scalable framework for evaluating peerto-peer protocols. Unlike systems based on simulation, emulation-based systems enable the experimenter to obtain data that reflects directly on the concrete implementation in much greater detail. This paper argues that emulation is a better model for experiments with peer-topeer protocols since it can provide scalability and high flexibility while eliminating the cost of moving from experimentation to deployment. We discuss our unique experience with large-scale emulation using the GNUnet peer-to-peer framework and provide experimental results to support these claims.

Large-Scale Deployment in P2P Experiments Using the JXTA Distributed Framework

The interesting properties of P2P systems (high availability despite peer volatility, support for heterogeneous architectures, high scalability, etc.) make them attractive for distributed computing. However, conducting large-scale experiments with these systems arises as a major challenge. Simulation allows only to partially model the behavior of P2P prototypes. Experiments on real testbeds enc...

PeerfactSim.KOM: A P2P system simulator - Experiences and lessons learned

Research on peer-to-peer (p2p) and distributed systems needs evaluation tools to predict and observe the behavior of protocols and mechanisms in large scale networks. PeerfactSim.KOM1[1] is a simulator for large scale distributed/p2p systems aiming at the evaluation of interdependencies in multi-layered p2p systems. The simulator is written in Java, is event-based and mainly used in p2p researc...

Searching in Unstructured Overlays Using Local Knowledge and Gossip

* This paper analyzes a class of dissemination algorithms for the discovery of distributed contents in Peer-to-Peer unstructured overlay networks. The algorithms are a mix of protocols employing local knowledge of peers’ neighborhood and gossip. By tuning the gossip probability and the depth k of the k-neighborhood of which nodes have information, we obtain different dissemination protocols emp...
