Ciao- I'm working on a study of node reachablity and mixing dynamics for random walks. To that end, I'm collecting both topologies from live systems and various project simulators which build topologies in a realistic manner. I'd like to include Freenet in the study, but I've ran into a bit of a snag.
I've been looking around for a simulator of Freenet without success. There is the old www.neurogrid.net simulator, but it appears extremely out of date, particularly when considering the architectural changes to Freenet since 2003. Similarly, there are Hui Zhang's http://netweb.usc.edu/~huizhang/freenet.html (old, code doesn't inspire confidence), and EOS http://www.skoghs.se/eos/ (old, but the code is promising). In the dual thesis of Jonas Haeggstr?m and Hans-Emil Skogh, the same fellows who wrote EOS, they mention two simulators borne out of the Freenet project itself, Aurora and Serapis. Neither of them appear to be in the current SVN tree, and I can't find the old CVS tree except via Sourceforge's Krugle code search. And what I find there has a copyright of 2001... Is there something more up to date than all this? In particular, is there a simulator that accurately builds topologies that mimic the actual Freenet deployment? There also appears to have been recent discussion on adding more instrumentation to the running Freenet network in order to develop a deeper understanding of the live topology. Has anything come of that? Thanks, Cyrus Hall University of Lugano Department of Informatics
