There's definitely no one-size-fits-all solution when it comes to sizing
and managing an internet pipe. We have been using what we felt we could
afford, which amounted to 4 T-1s to serve a population of about 450
boarding and day students and faculty/staff. Until recently we'd been
using a Packetshaper to partition bandwidth between the student network
and everything else and adjusting our partitioning by time-of-day. The
Packetshaper also gave us the ability to prioritize certain applications
and to throttle those that were causing major bottlenecks and had no
educational value. I have found application-based controls to be less
effective than they once had been and so we now use a product called
NetEqualizer to maintain fair access to the bandwidth we have regardless
of application. Even with traffic management tools in place, we have
found our bandwidth to be inadequate to serve our community and have
recently purchased significantly more bandwidth to keep up with demand.
Feel free to contact me off-list if you want more detailed info.

Subject: Internet Bandwidth --> How did you come to your level?
Hi Everyone,=20
I really enjoy the list and have been reading for the last few weeks to
get
a better sense of the issues facing independent schools and technology.
My
question to the list relates to internet bandwidth. I am sure there have
been may threads on this in the past, but just wondering what metrics
you
use to measure what is sufficient for you? Does it make sense to try and
gauge how much internet connectivity you need by student count or do you
break-up the connectivity between faculty and students? Have you
isolated
bandwidth-intensive courses or done any segmentation or isolation at
all? Do
you use and QoS to handle application/device priority or is that not
really
a concern for independent schools?
Thanks and any feedback appreciated,
Jonathan
