Oskar, I'd like to start work on a timestep sim with you in a week or two (after I get the crypto done). I expect it'll be about a two week job.

In my proposal, the entire network is a finite state machine, stepped as a whole. The network is simulated with these steps, one can hold back packets to simulate latency, deliver chunks per step to simulate bandwidth. I'm building it on top of another project of my design, Gamora (http://gamora.org). Its essentially a self-organizing event routing framework that pretty much makes this an academic excercise. I just need help to mimic the node behavior (as far as what it does when it receives messages, and the like). The nice thing about the system is you can transparently insert components without affecting the rest of the system or doing any extraneous coding. You can insert a monitor along a link to intercept messages or dynamically affect network conditions. Or you can insert an "attacker" into the system at any point, at run time. I envision the frontend looking like the GUI currently checked into Freenet.sim now, plus windows where one can "be a client" to insert a new message, and then follow that UniqueID through the system, watching each node light up when it receives it, as well as get timing statistics. Because its a timestep simulator, one can pause, fast forward, play in real time, perhaps even rewind the simulator. scott -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.1 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE5DhohpXyM95IyRhURAprzAKCn8u1NBW81/0BqCDP+04UtC5pFGwCdFhCs ZNOiZxytVWnEXtE8LyeSz44= =M2EA -----END PGP SIGNATURE----- _______________________________________________ Freenet-dev mailing list Freenet-dev at lists.sourceforge.net http://lists.sourceforge.net/mailman/listinfo/freenet-dev
