Evaluating large scale distributed simulation of P2P networks

P2P systems have witnessed phenomenal development in recent years. Evaluating and analysing new and existing algorithms and techniques is a key, issue for developers of P2P systems. In this context, simulation is an important tool for P2P developers. However, such systems are often very large and few existing simulators offer the ability to execute simulations with an Internet scale. In this paper we utilize parallel discrete event simulation simulation techniques for executing large scale simulation simulation techniques for executing large sclae simulation of P2P systems which sclae effectively, only limited by the amount of comutational resource available (memory and CPU). We show results from a number of P2P protocols, indicating goood scalability both in terms of size (memory) and execution time (CPU). The results demonstrate how the differences of these protocols and which of the underlaying factors affect the performance of the distributed simulation infrastructure.
