Mike, Rick:
I think it'd be *huge* to add some traffic shaping to LEAF,
with the caveat that we provide a setup interface to it as well, in
the same manner that we provide one for ipchains. That is, we pick
a shaper/bw-manager package, and we bundle it with a script of
the same UI-flavor as our firewall script.
I was looking once at a CBQ solution, and convinced
myself that I could get away with only three bandwidth "classes"
or "priorities" for most target LEAF installations: high-speed,
low-speed, and "time-critical" mode. High-speed would be what LRP
is without shaping, and low speed would be used to intentionally
sit on some LAN machine's peak bandwidth (eg, Junior's PC can only
get 56k). The "time-critical" class would be to suit people using
VoIP, Quake, or other streaming apps that want isochronicity.
Given the ability to provide one of these three modes
to every machine on the LAN, one a machine-by-machine basis,
I think is a 90-percent solution. The ET/BWMGR from Etinc allows
(shiver) "10 levels of priorities...with multiple class groupings".
Excessive, IMO. And, from the "Grand Fireewall Paradigm" thread,
we'd let these modes get specified in the same place and manner
that we specify port-forwarded services.
IMNSHO, of course. :)
