Most vendors claim to be able to look into the payload and determine
that it is p2p traffic instead of http/https traffic. I know I have
looked at several of these vendors myself, and most of them did not have
hardware that was even safe or reasonable to deploy, as certain traffic
would send the unit's CPU towards 100% with only a measly 1 megabit of
traffic. I personally eliminated on of these vendors from consideration
this way.
Sandvine seemed to have a pretty decent hardware solution when I was
still in that space 2 years ago, with only a few concerns. I'm sure
that they have vastly improved. They were also less "religious" about
99% of the internet traffic being p2p, like some vendors were.
Still, while I support the ISP's right to manage and shapre traffic, I
still think this is a poor tactic. This is like your telephone company
hanging up your call, regardles if the content of the call was a drug
deal, a call to grandma, or a call to e911. It's just not morally right.
