Modeling the Internet Delay Space and its Application in Large Scale P2P Simulations

The peer-to-peer (P2P) paradigm has greatly influenced the design of Internet applications nowadays. It gained both user popularity and significant attention from the research community, aiming to address various issues arising from the decentralized, autonomous, and the self-organizing nature of P2P systems [379]. In this regard, quantitative and qualitative analysis at large scale is a crucial part of that research. When evaluating widely deployed peer-to-peer systems an analytical approach becomes, however, ineffective due to the large number of simplifications required. Therefore, conclusions about the real-world performance of P2P systems can only be drawn by either launching an Internet-based prototype or by creating a simulation environment that accurately captures the major characteristics of the heterogeneous Internet, e.g. round-trip times, packet loss, and jitter.
