I've been looking around for a tool to do this and found NIST Net, which is a Linux kernel patch that lets you simulate things like loss,latency, and bandwidth on the IP level. http://dns.antd.nist.gov/itg/nistnet/
Unfortunately by the looks of it, it doesn't let you simulate the typical up/down bandwidth bottlenecks we're dealing with. I'd be willing to write a deamon that would listen to 1000 ports and forward those to other <IP,ports> and apply simple delay and bandwidth limits at the TCP level. If someone has a LAN with a couple of machines you could set all the nodes up as if they were behind a firewall/NAT with address X. We could then put this little monster on a macine with address X and have it forward to all the nodes appling limits. Does this sound like it would work? This would still leave the other end of simulation open. We have to set something up which requests and inserts like real people do. Do we have to simulate Frost usage? __________________________________________________________________ Gesendet von Yahoo!
