What vendor switches do you have? If its cisco you can use netflow collector software.

You need to setup a proxy server between your network. The proxy server (Cache+firewall) will log all the ftp and http based downloads. You can even restrict sites, limit the bandwidth, and monitor the bandwidth. There are two industry standard software-based proxy servers;

1- MS ISA Server

2- Squid Cache Server

I personally recommend squid because it has all the basic features built-in and is open-source (free).

You may also have a look at hardware proxy appliance like bluecoat;

uetian1707's suggestion of Squid is great for detailed monitoring of several protocols but doesn't quite capture everything you may want.

so long as you have a managed switch capable of port mirroring, something like Ntop is a perfect tool to collect detailed network statistics so you know who is taking up your link, what resources their using, how long, etc.  While Ntop does do Netflow, from what I've heard mirroring traffic to the ntop server is more reliable than using netflow.

Port mirroring is good..I've never ran into a issue with netflow. The benefit of netflow is that you can run it on any device that supports it. No needs set up aggregation points.
