Re: copyright infringement notices volume

[Dave Inman <dave.inman () VISTAONE COM>]

Our experience with Procera and other traffic shaping solutions generally
leads us to believe that the best practice for managing P2P traffic like
BitTorrent is to limit it to extremely low bandwidth, rather than to
filter/discard it completely.

When these applications are blocked, they kick into overdrive to obfuscate
themselves, which increases the likelihood that they will get around the
PacketLogic's signatures. Limiting the bandwidth consumption by shaping, on
the other hand, will make the applications think that they're working, but
make them so slow that they are effectively unusable.

Of course, with PacketLogic's ability to create objects and policies based
on such a variety of properties, you may be able to combine a filtering rule
based on application signature with a shaping rule based on flags.

Hope this helps...
