Remember that Sandvine Thread ?

»Comcast is using Sandvine to manage P2P Connections

All the info you'll need is in there.

Basically, you need to use an App such as Wireshark, and you are looking for forged TCP RST packets.

The "Search Topic" feature is your friend my Son !

Here are some links to relevant info, the first link demonstrates another method. It was authored by funchords:

»How to test how many connections are being reset by RST pack

»[Speed] There are good resets and there are bad resets...

»Comcast is using Sandvine to manage P2P Connections

You may decide that none of this is worth your time... Y.M.M.V.

 hm, well i turned on encryption on utorrent..that seemed to help..i'm currently not downloading just uploading (seeding) but my upload speeds seem to hovering around 60-110 kb/sec.

Seems like it has a mind of its own..I'll check into those threads you posted later..Thanks for helping out.

 I found this test from DSLR, I was going to post it in the famous Sandvine thread, but couldn't find it..

»broadband.mpi-sws.mpg.de/transpa···test.php

Scroll to bottom and click full test, *note* don't use your connection for other stuff while testing.

I just tried testing though, and got a server busy error, I'll post the results when I'm able to run the test.

Edit: Its a test to see if your ISP blocks/delays bittorrent.

I, personally, question the efficacy of that test.

It only tests on 2 ports, and I can't see what is going on behind the scenes so I'm basically forced to blindly trust it..

I.M.O., there is nothing to compare with seeing actual rogue RST packets via a packet dump, but that's just me.

It may indeed be an effective test. Y.M.M.V.

I found it for you. See the search box at the top of the forum. Type Sandvine there and click the Go button. You get this ---> »/nsearch?board···Sandvine
