Bandwidth Simulation Test

[robistech]

Hey everyone,
So I finally got all of the equipment set up to begin a live morning broadcast for the announcements at my High School. We're planning to stream the video live to about 35 classrooms simultaneously in the beginning of the day. I have some more details below, but my main question is, does anyone know of a bandwidth test/simulator I can run on the network to see how the load is doing and if this is even possible? My last resort is to manually go to each classroom and go the webpage, but I need to do something to make sure we don't creash the network on launch day. Any ideas?
Thanks!

Details

• School Bandwith is from local cable company. Speeds are 12/1.75
• We've been lucky enough to partner with Influxis for streaming bandwith, so we will not be connecting to a Ustream or Justin, but to a simple webpage running Influxis embed. on a webserver on the nwtwork
• I'm not sure about all the specs, but I believe the school has a pretty beefy infastrcuture.

Just on a side note, we're not planning to broadcast in HD. We'll be broadcasting at 480P SD, probably at 500k.
