Hi Listserv,
Since I've learned so much from others experiences on this listserv, I thou=
ght I would what I've learned about student bandwidth.
We use 100 mbps per 1000 students - which translates to roughly 4k-5K devic=
es on the student network (ipads, pc's,macs, gaming consoles, iphones, smar=
tphones etc....) this year we wound up with 2-3 devices per student average=
. Some have many more.
We currently run a 200 mbps pipe. That's more than adequate for 2000 stude=
nts in a residential college.
Before the Netequalizer was installed, we were thinking that we would have =
to upgrade to 300 mbps by mid this year - at this point I don't see having =
to upgrade until sometime in 2014 unless something drastic changes in the i=
nternet. Maybe not even then.
What you really need to consider is how the bandwidth is shared. We found =
the perfect solution in the NetEqualizer.
It's "Behavior-Based" shaping algorithms allow for a very high number of de=
vices all sharing the same internet pipe, and slowing the "Bandwidth Hogs" =
while allowing those using smaller streams to pass unhindered. It's really=
a great product, and will pay for itself in no time at all. (It's pretty =
inexpensive to purchase and yearly maint is hardly anything compared to the=
"Deep packet inspection" devices.)
A great deal of wireless ISP's use NetEqualizers to keep customers from sc=
reaming about slow internet access - many colleges and universities are usi=
ng it for the same reasons. It's true power (IMHO) comes from connection =
limits - each student is limited to 20 connections (10 up/10 down) which pr=
events P2P from doing much of anything - no RIAA notices and keeps the pipe=
clear for others. Since the connections are only tracked for a second or =
two - the students don't see themselves as restricted - but yet it works am=
azingly well. This has really cleaned up the traffic on the internet pipe,=
and it what has allowed us to remain at 200 mbps....This setting can be mo=
dified, we just settled on following limits which have worked well for us: =
wireless users 20, Wired 30, Gamers 60. (Some game consoles use torrents fo=
r legit updates.)
Overall, the student segment is allocated a bandwidth pool of 180 mbps - wh=
en traffic reaches 85%, the box begins slowing the largest "Hogs" packets b=
y fractions of a second until they start to slow down, thus allowing everyo=
ne to get decent response times. If the link isn't saturated beyond 85%, pe=
ople get blazing fast responses and downloads.
It's become very apparent to me that much of the traffic clogging our syste=
m prior to the installation of the NetEqualizer was frivolous crap communic=
ations, P2P etc.... even with the old Packeteer supposedly doing it's thing=
.....since we cranked down the connection limits, the students machines are=
not free to make hundreds or thousands of connections thereby keeping the =
pipe clear for others. It's really been amazing. The old packeteer didn't=
perform anywhere near this efficiently.
I am a strong advocate of this product - I would be happy discuss how we us=
e it/how it works with anyone who is interested - this is the best product =
I have ever seen in this arena. It's truly a set and forget device - it doe=
s its job 24x7x365....no issues.
I understand this may not be a big issue for those that have massive bandwi=
dth to the internet, but in some cases like ours; that bandwidth is very ex=
pensive and why purchase more than you really need?
Hope this helps provides some food for thought....

Colleagues
We are in the midst of expanding our residence population and working on st=
andards of service.
Does anyone use a formula for calculating minimum or optimum bandwidth for =
ResNet, such as bandwidth per resident student, or a similar approach?
