Here is a link that does a decent job describing the Mikrotik
implementation using burst-limit, burst-threshold and max-limit. Scroll
down to the section labeled "Burst" (second to last section).

Subject: [WISPA] Advanced Bandwidth Management
Several times in the last few weeks the topic of bandwidth
management has been discussed, but "I Still Haven't Found What I'm
Lookin' For"... Here's what I'd like to do:
1. Each user starts with a big "Internet Pipe". This way casual
surfing and emails, etc. happen nice and snappy.
2. If a user downloads a big chunk of data, he needs to be "shaped" to
a lower data rate after a few minutes (I'm thinking 2 or 3 minutes).
3. Step 2 repeats over and over several times if the user continues to
4. After the user quits hogging the network, his bandwidth is restored
in stages (backwards of 2 and 3).
I know this, or at least similar things to it, are being done out
there. The HughesNet satellite FAP works something like this (I don't
know the actual values):
1. Each user has a "Bit Bucket" that holds 1 Gig of bandwidth.
2. The "Bit Bucket is replenished at 128k.
3. The speed at which the user can download from his "bit bucket" is 1meg.
4. If the user uses all the bits in his bucket faster than they are
replenished, he eventually gets only 128k.
Does anyone know how to get something like this going? I am especially
interested in Linux/Ubuntu solutions.
