Andrew,
Our network admin told me that our campus does not limit the number of connections because there are "legitimate" services that will open a number of simultaneous connections; he named Facebook (40+), CNN (50+), and Ebay (150+) as examples. How do you get around that? If we blocked any one of those I think the students, staff and faculty would send out a lynching party...

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 noti!
ces 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...
