What is the best software or device to monitor bandwidth usage and prevent or detect a DOS attack?

Our router is getting horrible ping response times of 298, 2240, 600, 300... very sporadic, but this is only occuring when we plug in the fiber connection that connects our high school to our main wiring closet.
Unplug the high school and things are okay, back to normal... So something up there is causing this and I've downloaded Fluke Networks Network Inspector, GFI Languard, Retina Network Scanner... Wireshark.
Just wondered if anyone has used anything successfully to detect where the traffic is coming from. We're currently unplugging entire labs and switches at the high school from our network just because it's killing people on bandwidth.
Also, is there a bandwidth throttling program or hardware device that wouldn't let this happen? We have a Sonic Wall Pro 5060, but it didn't seem to help this at all.
