Gregory. I was in the same place you were last spring. Due to increasing =
bandwidth I was looking at significant licensing and hardware replacement o=
f our shapers. I was also beginning to see the end of the tunnel in terms =
of deep packet inspection with regard to prioritization of traffic. We had=
been changing what we wanted out of our shaper from prioritization to equa=
lization. While we wanted to prioritize by application on some things, wha=
t we really wanted was to share the bandwidth equally between our users, re=
snet and other. While I couldn't do everything I wanted with the NetEq, I =
found that those things I wanted to do, I really didn't need to do. We hav=
e been up on ours for about 7 months now, and we have had nothing but a ter=
rific experience.
In the midst of this I also took some data on user population to bandwidth =
(Mbit/second) and found that with any kind of packet shaping, the sweet spo=
t of user/bandwidth ratio was 4:1. I also heard from many that were higher=
than that, 6:1, 8:1, 10:1 even as high as 20:1. We run at 6:1 and 9:1 on =
our two campuses. There have been no significant complaints.
I see that Andrew Wolf has responded to your message as well. He was the =
one that convinced me to get an eval and give it a test drive.
The one problem I have with the NetEq is that the network interfaces aren't=
pass through by default. I got very used to that with our shaper. You ei=
ther have to set up your own switches to bypass it in the event of a failur=
e, or buy a solution from them that does basically the same thing. Other t=
han that small complaint, I have had no problems and more importantly almos=
t no bandwidth help desk calls! That's the big plus. Plus it is very eas=
y to manage. I hardly ever touch mine. I just monitor them with the new D=
ashboard interface.

Subject: To Shape or not to shape
Good evening all,
We are in the process of trying to decide whether or not to upgrade or all =
together remove our packet shaper from our residence hall network. My netw=
ork engineers are confident we can accomplish rate limiting/shaping through=
use of our core equipment, but I am not convinced removing the appliance w=
ill turn out well.
So...what are other universities using a packet shaper for and if you no lo=
nger use it, why did you remove it and what is its place?
Thanks!
Greg
