Bandwidth monitoring per IP device?

I'm looking for a way to monitor bandwidth on a wireless LAN. I need to be able to see how much bandwidth any particular device on the LAN is using at any given time. This can be shown by IP address or MAC address.

Ideally, it would break down like...

192.168.1.a is using 654kbit
192.168.1.b is using 322kbit
192.168.1.c is using 12kbit
192.168.1.d is using 0kbit

How could I accomplish this? Would the router need any special features/logging/etc?

Bear in mind that most devices on the network will not be able to run an SNMP client.

You want netflow or netflow like statistics. If the AP is the layer 3 gateway or your gateway is a Cisco router you can export the netflow statistics and use Netqos or any number of free and not free products to analyze and correlate the data.

Other network products support netflow, but I don't have much in the way of expertise on those, so no suggestions there.

Response by poster: @odinsdream: I have access to dozens of MikroTik routerboards and am behind one currently. I was not aware that they had this ability. Can you please explain how I can utilize one to show this breakdown of bandwidth information?

Cacti + SNMP. Most OSes have SNMP implementations available for the installing.

Packeteer's PacketShaper (and other related products) does this, and can limit people to boot. Depending on your budget and intended use, it may be either just the ticket or overkill.
