Hi Ana,
I looked at Packeteer years ago and at that time they were leading the
pack in
their ability to do QOS filtering. They were one of the top candidates I had
asked
to come to the QCon but due to a trial in Japan at the time could not come.
With regard to Packethound, this is being tried here in RTP and it looks
ok but
has some limitations. As long as one is aware of those limitations then the
product
is ok (case of if a tool is not used for what it was designed one must be
careful of
the results). My quick view ov Packethound is that it must be inline with the
main
pipe into campus. For us that is a problem since PH only goes to 100Mbits and
we
are at 1Gig coming in. Second the tool works on predefined apps (ports) which
you
can choose from but does not coordinate the top talkers with bandwidth used.
just some thoughts,
john
