I'm probably going to get slammed for asking this, but does it have to
be a technical issue? Moving 1 TB of data over wireless is really not
fair to the other clients. If the usage is necessary, and you have wired
Ethernet in place, I would try to have the user move to using the wired
I agree with Heath on this one, I would view a student transferring 1 TB of
data over our wireless network as being a non-technical issue and more one of
education that, that is an incredibly selfish action if done during peak times,
maybe a fair use policy is required?
That being said I have
I'll chime in here too, with our approach. The majority of our dorms are
wireless only, so we can't really push people onto the wired network to avoid
things like this. We wouldn't want to do that anyway, however, as the dorms are
home for our students. The great majority of students are coming
It's unlikely that QoS is going to solve this problem unless you can properly
classify the backup data from everything else. Depending on the age/type of the
AP, it's firmware, and the clients connected to it, ensuring fair use of the
radio may be more of a problem than the amount of traffic

Nick,
With BlueCoat packet shaper, you can use dynamic partitions for the
dorm subnet to insure fairness to a certain extent. Or you can setup a
partition to limit the backup traffic. If the backup traffic is
encrypted then it's game over unless you want to use adaptive
response, so when a user

You could also approach it from different angle. Work with the student
to see what/why he's backing up. It sounds to me like he's backing up
his entire hard drive (500+ GB?) multiple times a week. That in itself
seems a little ridiculous/paranoid. See if maybe the service he is using

Normally, these services do a whole backup, then only the changes afterwards.
So it could just be the initial backup. I did the same thing with Carbonite
recently, and besides taking a while with a relatively slow upload, there were
no issues. My ISP certainly didn't let me know they cared :)
I like the idea of limiting based on usage and time.
The incident involving the 1 TB of data was a connection between a Mac and a
Time Capsule connected to the same AP using Time Machine. The data never
traversed our internet connection.
Most of the problems we are experiencing could be solved
Procera will do that exactly

It seems like you should be able to control the traffic out to the internet if

Will it limit traffic going from one client on a particular AP to
another client on the same AP?

Lee,
If you have a stack of Cisco switches, say a pair of 3750G's connected
via stackwise, you can split the trunks between the two. on something
like a 6509, the ports can be split between line cards (that's what I'm
doing with my 5508's).

I don't feel there is anything lacking in Cisco's product, but there are still
rough edges that need a little work. That said, Cisco made a big leap in the
6.0 code, and it appears that 7.0 will improve on it.
I just made the leap from the older 4404's to the 5508's, and boy are those new
