Re: Dragonfly

Like many others, our Athletics department uses it to share game films.
This past weekend I noticed that the computer they run it on was using
about 60Mbit/s for a few hours and got up to about 80Mbit/s for a little
while.  For us it has not been an issue at all since they are mostly
sharing with other local colleges who are on our I2 connection which is
not anywhere close to being maxed out.  Also, we don't do any packet
shaping on out I2 connection.  So basically what I am saying is that our
Athletics department uses it and it is a great use of our otherwise
lightly loaded I2 connection.  It looks like they can now share videos
in a matter of hours to many other sites all at once compared to the
slow and very manual way of doing it in the past.

Back when the Athletics dept was looking into it, we had a conference
call with Dragonfly and they asked us all about our internet connections
, told us things like how their software was P2P, used port 6011 and
port 80, etc. and were very willing to work with us if we had any issues
or concerns about the software.
