We installed a behavior-based shaping device (NetEqualizer) that controls the
amount of total simultaneous connections an IP address can make, in addition
to controlling bandwidth hogs. P2P is held to a minimum because P2P activity,
in general, creates many connection simultaneously, normal web traffic does
not; so limiting connection is a very effective P2P controller without actually
stopping legitimate use. The power of the unit is both connection limits and
shaping large bandwidth streams; everyone gets a piece of the
inbound/outbound pie, and if the trunk is not saturated, they also get max
performance. When many students are in contention for the internet, and the
trunk is saturated; large streams get slowed by the NetEqualizer (fractions of
a second) until they back down to a reasonable level. It slows the hogs in
small increasing increments, and everyone gets through. Small streams
(Skype, Voip, simple web browsing, etc)….are unaffected and no one really
notices that they are being controlled. This product has made management of
student traffic a no-brainer these days, we used to spend a great deal of time
managing the old packeteer, but no more. I love this machine ! (and we
haven’t received any RIAA noticies!..and virtually no student complaints about
slow internet!) Did I mention that I love this machine? and it has a great
return on invesment.
I hope this helps...
