Rockville, MD | what's data got to do with it?
the FCC don't need no stinkin' data; they rely on what their industry buddies tell them to do. |

| Random ports?
Random ports don't affect Sandvine or other DPI boxes. They see the headers in the packet, they know it's P2P no matter what port it is on.
Encryption on the other hand can be hard to track, but that all depends on the setup of the session and if it can be tracked accurately through a signature.
But I do know that encrypted NNTP just shows up as SSL to DPI, no way to know it's NNTP in there. |

| Re "they aren't telling"
said by TFA :
How much of the traffic on the internet is peer-to-peer file trading? Everyone seems to agree it represents a lot of the traffic, but the truth is no one knows (with the possible exception of the ISPs and backbone providers in the middle, and they aren't telling or sharing raw data).
Of course they are not telling. If they did then their argument for throttling P2P would collapse. Now that would be very "telling" 
And BTW guess who owns a stake in Ellacoya? »www.ellacoya.com/news/pdf/2005/E···ding.pdf |

It can be heuristically tracked in aggregate by looking at the connection stats. P2P traffic is easy to spot if you look at active TCP session number stats per IP address. |
