As we discuss commercial systems with lots of bells and whistles, I think
there may be interest in some discussion of lower cost solutions which get
the job done. I would like to see further development of open systems in
At Roanoke College we have been running a Linux based system for 10 months
which very effectively meets our needs. Our DS3 was maxed with outgoing
traffic in December of 2001 so we began limiting large packet out going
traffic from the residence halls to 5 mb over non http, ftp, etc. ports.
This solution allows both firewall and packet limiting for a cost of an
industrial strength PC and a ROM card to minimize moving parts. Our traffic
immediately dropped to 15% utilization and equal incoming to outgoing
traffic. We have noticed this year a 100% increase in traffic but still
well below max.
