Helena,
Packethound is a nice niche solution but as I said for those campuses that
have OC-12 or Gig entry pipes one would have to do some strange things like
use multiple boxes on certain building pipes.
I stand corrected on the ports issue, I meant to type (??port??), as far as the
liability issue I will leave that to the attorneys. I thought the main issue
was to
restrict frivolous bandwidth useage that some of the applications like Napster
is consuming.
I did not know that Packethound can tell one how much of the total bandwidth
the tracked signature traffic is using??
Are you planning to release an OC-12 version as well as a Gig version. I would
like to see how it compares to other products like Netscout. I would be very
interested in trying that version out.
cheers,
john
