Hi all. I have a bridge running Linux 2.4.24 that I use as a
bandwidth manager on a broadband wireless network. I''m using HTB and
SFQ to prioritize that share bandwidth on a per-cell basis. My IP
tables rules divide the traffic based on IPand traffic type (using
layer-7 filter and ipp2p). My goal is to make sure that p2p traffic
on the network doesn''t sink all of the bandwidth and affect the
performance of high-priority commercial customers. For the most part
it works very well, but I''m not getting the kind of prioritization
I''m
expecting. I''m not seeing p2p traffic go down on my graphs as
higher-priority traffic goes up. Consequently, my high-priority
traffic suffers. I am able to control the p2p but putting it into a
very small bitrate queue but would rather late the shaper do the work
based on priority.
What am I missing? My rules are posted below.
Thanks,
Michael Eck
Sorry if these are a bit long
