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.

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.
