Design and Implementation Aspects of a novel Java P2P Simulator with GUI

摘要

Peer-to-peer networks consist of thousands or millions of nodes that mightjoin and leave arbitrarily. The evaluation of new protocols in realenvironments is many times practically impossible, especially at design andtesting stages. The purpose of this paper is to describe the implementationaspects of a new Java based P2P simulator that has been developed to supportscalability in the evaluation of such P2P dynamic environments. Evolving thefunctionality presented by previous solutions, we provide a friendly graphicaluser interface through which the high-level theoretic researcher/designer of aP2P system can easily construct an overlay with the desirable number of nodesand evaluate its operations using a number of key distributions. Furthermore,the simulator has built-in ability to produce statistics about the distributedstructure. Emphasis was given to the parametrical configuration of thesimulator. As a result the developed tool can be utilized in the simulation andevaluation procedures of a variety of different protocols, with only fewchanges in the Java code.
