Our Cisco routers do UBRL which I believe stands for user based rate limiting. It sets bandwidth per IP address and works pretty well.

Subject: Bandwidth Management - Dynamic Allocation?
Hello All,
We currently have a Packetshaper that is at the limits of its capabilities
and we are looking to upgrade. I've searched through this and various other
lists for information on solutions from Procera, Exinda, and the
NetEqualizer, but was wondering if there is a simple solution out there that
basically just takes all the devices online, and carves up the available
bandwidth equally.
We currently use our Packetshaper in this manner via dynamic partitioning
and if there is a low cost solution that manages bandwidth in this way
without doing the layer7 application analysis, that would be very tempting.
I had originally hoped that the NetEqualizer took this approach, but my
understanding is that it allocates the bandwidth equally based on flow, not
device (IP). It seems to me that that approach would favor P2P type
applications that open up a bunch of connections at relatively low bitrates.
We have ~4000 users and anticipate managing somewhere around 1Gbps in
bandwidth within a few , so any solution we look at would have to be able to
manage those kinds of numbers.
Thanks in advance for any responses.
