Hello again,

Is it possible to split a bandwidth equally among clients regardless of its
current link speed?

I have a link that can get bursty at times. At any given time the N active
sessions (the ones with non-empty queues) need to be serviced
simultaneously, each at a rate of 1/N'th of the link speed.

Is this upstream or downstream traffic?


If it's upstream, what causes the variation, eg. is it RADSL and you get a long queue in your modem buffer, or is it shaped later at ISP - what is the link type/behavior ?


My case is an internet connection that oscillates between 96 kbps and 256 kbps. I cannot predict the connection speed in order to use the classical HTB (to set up a 96/96 kbps class), because I would loose a lot of bandwidth when the speed goes over 96kbps.

This might not be a strictly HTB related question. It doesn't matter if I
use htb, cbq pr other technique. I do not have to guarantee a certain amount
of bandwidth to one computer in the LAN, just to split the existing
bandwidth equally among the N active clients.


I know... Someone said here "Use sfq or esfq". Unfortunately I am not very
bright and a piece of code would be excellent :) In fact I tried a lot of
setups but did not get any satisfactory result.

Depends on the exact nature of your link, hardware and the direction of the variable rate. It may be impossible/possible/a bit possible more detail is needed.
