I've been following this thread with interest. I'm always interested in ho=
w we could be doing our bandwidth optimizations better. Both the overall a=
mount and how we slice and dice it are interesting to me.
It seems that the answers all bear a similar proportion to me. Almost all =
of the respondents that were not getting wiped out seemed to have a ratio o=
f students to Mbps in bandwidth that was about 4:1. That is where we are p=
lanning to go to this year on our college campus and on our K-12 campus. I=
'm glad to see that the ratio is working at numerous sites of all sizes.
What I have is a question about the 2nd bit. Slicing and dicing the bandwi=
dth up among users. We have been a Packetshaper client for years. We have=
purchased 5 of the boxes over the last 10 or 12 years. But I'm beginning =
to wonder (like someone else who answered this topic) if the deep inspectio=
n identification is the way to share traffic. Would it be better to jump t=
o some other technology that spends it's time dicing the bandwidth fairly a=
nd equally between the people using the bandwidth? I am thinking so, and a=
s we get larger and larger amounts of bandwidth, the cost of a device like =
the Packetshaper is leading me to think I'm right. So, especially any of y=
ou that have made the jump from Packetshaper to something else, what is you=
r opinion/feelings about the jump you made. What were the reasons you made=
the jump? Does your new solution do what you wanted it to do? Especiall=
y those who were looking to share out the bandwidth equally among your stud=
ents. I will find it hard to give up blocking traffic like P2P as I do wit=
h my Packetshaper. I'd love to know what you are using and why you went wi=
th it and more importantly, how it is meeting your needs. I'll summarize i=
f folks want, but I really would love to hear from you.
Thanks.

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?
