Comcast is forging packets

It is my understanding that this form of traffic shaping involves the forging of packets such that it looks like I am sending the packet with the RST flag set.

As far as I'm concerned, this should be illegal.

There's a pair of injected (forged) packets; one going to the peer with the src/dst forged and TCP RST set, and the other going to the server with the src/dst forged and TCP RST set.

Both ends of the connection receive the packets -- that is to say, the Torrent server (or other peer, if P2P) will see the forged RST as well.

The EFF's statement sums up, in a nice way, what I've been saying about this for quite some time. It does set a very dangerous precedent, and it *completely* destroys the guaranteed stateful nature of TCP.

I'm still baffled why no reporter has asked Vint Cerf his (personal, not professional-at-Google) opinion on this matter.

I agree. I don't care what the CC fanboys (as another poster called them) have to say about TOS. These ISP's are becoming to be no more different than China and all the internet blocking they do. At least I know ahead of time what to expect from China. Comcast, Rogers, and the others do it in a sneaky manner. The only reason our ISP's do it here is because they don't want to spend money on expanding & improving capacity. When it was analog cable & internet with 5mbps\384kbps there was plenty of room for everyone. Now with HiDef cable, phone, and 20mbps\5mbps internet they want to squeeze all this information over the same pipes. It seems the only way to do that is to limit what we do with the internet side of things. So Comcast & others at least be honest with why you are hacking your customers internet traffic. Where does it stop? If you get upset about the negativity you receive on particular websites (DslReports) will you block the traffic of certain users and only let your 'fanboys' cheer for you. At least the Comcast, Rogers, & Verizon company colors already match the red in the Chinese Flag.
