How to assign packages to users on Mac address basis.
do you know for a fact that their linux systems actually see the mac addresses of the subscribers' cpe?

Isn't it amazing how so many people can type "linuxpakistan.net" into their browsers but not "google.com"?

i haven't heard of any isp using linux for that, which is why i asked. if they use PPPoE (most common case in pakistan), then it's very simple: once you authenticate with their server (most likely a hardware solution -- a big expensive box like this, or software on linux), the device at the isp's end knows your ip address, and can limit traffic from there.

some isps also limit your link to the dslam to you. for example, i have a 512kbit link at home, and my modem reports 512kbit down/128kbit up. at work, i have a 1mbit link, but the modem reports 4092kbit down/1020kbit up.

Usually BW management modules are built in Billing systems. Huge variety out there.

Mastershaper is a cool Opensource QoS project

Upto you how do you use it. I prefer FreeBSD dummy net or OpenBSD AltQ for traffic shaping.

There are several ways to do so. They can assign bandwidth on D-Slam port on which you are connected or else they can do it via their billing system (billing will add a queue automatically against IP when user get authenticated.

We use PacketShaper (www.packeteer.com) for such limitation and its very authentic way to limit end user bandwidth
and
you can also use Mikrotik as packet shaping for your network
