It's my assessment that you're short on bandwidth - most schools have 100 to
200 kbps/FTE, so even if you look at just the residences you should be at
240 Mbps.

Subject: New Stratagies to Meet Higher Bandwidther Requirements in the HD
Video World
I am curious if there have been any new approaches being used to better
manage the bandwidth requirements of our students today?
Saint Mary's University has approx. 6000 FTE's, with 1,200 in residence. We
have a BlueCoat Packetshaper 10000 which has served us very well. We are
facing higher bandwidth demands as our students have on average 4-6 devices
demanding bandwidth for streaming HD video and voice. I am sure we are not
alone in this situation.
Our campus has a 200M commercial internet connection which is where most
internet traffic passes, (except Facebook, Netflix, Google, and a couple
others), and this 200M link is managed by our PacketShaper. In our
PacketShaper we assign 150M (of the 200) to student traffic, and allow it to
burst to 175M, needless to say it is always running at 175M. We are using
the PS Dynamic Sub partitioning to divide the bandwidth evenly between
active users, and we do not classify based on traffic type (eg. Bittorrent,
Netflix, etc).
How are you dealing with the increased demand? Are you restricting more what
users are doing? (Something that would not fly well here). Increasing
available bandwidth?
Thanks,
