Hi Peter I suggest to use first net flow application which it will help to keep monitoring all your routers and switches and it will help you also to see which computer ip address is utilize most of the bandwidth. Also you can purchase any proxy server like bluecoat which will help manage the internet sites and blocked non work-related sites and add policy and restriction for downloading from the internet.
Bluecoat ProxySG can also manage bandwidth rather well in addition to the policy/category based blocking it can do. You can have a bucket, say for streaming media, and put a cap on that subset of traffic, a separate bucked for large iso/rar/zip downloads and have a separate cap on that total, and go from there. It's pretty handy. Now, the interface is ugly, and little bug issues might drive you to an early grave though (I have a good friend who's spent the last month debugging a randon reboot issue that BC can't seem to solve, and I've had similar less severe headaches with em too). Whatever you do, don't let them sell you on an undersized piece of hardware--force them to do a traffic analysis on your current network traffic and not just handwave based on # of users. And do get out your checkbook. Better price and performance proxy solutions exist, but none that I've found have as nice built in bandwidth management. Give em a proof of concept spin if it's in your budget. To all: any other proxies out there that do bw management like I've described?
