Our athletics department uses it as well.  We have it placed in a
restricted/secured VLAN and have also used our Packetshaper to limit and
de-prioritize traffic to and from it.  Despite what Dragonfly says it is
essentially a P2P application and therefore, in my opinion, should be
treated as such.


Thanks,

Brian

If so, I would be interested in hearing if you are shaping this
application's bandwidth or have taken any other measures to throttle
it down
and control the IP addresses it talks to.

Our athletics department has this, and it is indeed an incredibly
bandwidth-greedy application. We've got it in a throttled class using
our Packetshaper, which seems to be mitigating the resource use.

Yes, it stinks to high heaven.  As does XPressPlay, another favorite of
our athletics department.

Dragonfly is a rather specific protocol.  XPressPlay is essentially
BitTorrent.

We let our Procera's volume based shaping sort them out.
