Bruce,
Are these broadband customer using PPPoE or L2TP?   If so, I suggest  
looking at the capabilities of your BRAS to do the work.

Per user bandwidth quotas are the nature of the game here in Australia  
and doing it at the BRAS is the way we do it.   RADIUS gives you byte  
counts and gives you the ability to pass back rate limits etc.

What you didn't tell him is that the kind of shaping you can do
on the BRAS heavily depends on features used and platform. :)

64k policing mostly works everywhere, for example, but isn't
all that crash hot for your clients. :)

Doing more complicated hierarchical QoS on software platforms is
doable but complicated.

Others take a multi-tiered approach - they'll buy some kit to do
P2P identification/shaping, and per-user hard shaping in case they
go over quota.

Lots of cute stuff. :)

Hi,

Does anyone know of  any Shaping appliances to shape customers based  
on IP, allow for a quota per IP and qos mechanisms like LLQ?,  This  
is should be something that can sit in between two border router's  
and support a small ISP (20000 customers), also an opensource  
solution would be great!

Regards,

Bruce
