Hi,
I am a member of a software project group at Carl von Ossietzky
University in Oldenburg (Germany). We started our project this autumn.
The goal of this project is to simulate P2P-networks. Right now we are
in some sort of requirement analysis and exploration phase.
So we were looking for simulations tools for discrete event based models
and found Ptolemy II (and some other packages). While reading the
documentation of Ptolemy II we thought, this might be a good platform to
start our work. But I am not quite sure if it can really be used. So I
decided to ask this list, because you have more experience in Ptolemy
than I do :-)
First I want to explain, what we intend to do exactly. We want to
simulate P2P-networks with nodes acting as p2p-nodes, p2p-super nodes
and servers. These nodes shall be programmable (but this is a solved
problem) so we can simulate, messaging networks, streaming p2p nets,
backup-solutions and "normal"-file sharing networks.
To do so we intend to generate 100 and up to 10000 (or more if possible)
nodes in one simulation.
As far as I know, Ptolemy II can simulate networks in form of routers
and lines. And also connections between actors over these networks.
But now my questions:
1. Can Ptolemy handle 100-10000 actors in one simulation?
2. Will such a model still produce results in my lifetime?
3. Can such a simulation be distributed over several computers? (e.g.
grid computing, Beowulf or with java-runtime things etc.)
Thanks for you help
Reiner
