Peer-to-Peer (P2P) systems have become popular over the past few years. However, their large scale and the open nature of the system makes studying them challenging. This paper presents an extensible framework for simulating P2P networks efficiently and accurately. Efficiency is accomplished by using message level simulation rather than packet level(More)
Computational grids have not scaled effectively due to administrative hurdles to resource and user participation. Most production grids are essentially multi-site supercomputer centers, rather than truly open and heterogeneous sets of resources that can join and leave dynamically, and that can provide support for an equally dynamic set of users. Large-scale(More)
