Hi all,
I have perused the list archives and RTFM on ipfw
(which I use on this machine at home). I am interested
in investigating some free bandwidth management tools
and as a FreeBSD fan I'd like to use something that was
part of the core OS.
What I want to do is to restrict connections by IP
address to having a nominal bandwidth, but allow for
occasional bursts.
In going through the ipfw man page, I came across
pipe number config [bw bandwidth | device] [delay ms-delay]
[queue {slots | size}] [plr loss-probability]
[mask mask-specifier] [buckets hash-table-size]
[red | gred w_q/min_th/max_th/max_p]
and it looks like red/gred are important in traffic shaping
and maybe bursting. However, I have been unable to find a
description of what exactly the w_q/min_th/max_th/max_p
parameters mean.
Which brings me here ;)
Am I going along the right lines with this or am I already
tangential? Are there better, (preferably free) tools out
there that I can use for this?
Thanks,
Adam Nealis.
