From: http://text.broadbandreports.com/forum/r18944131-Re-Comcast-is-using-Sandvine-to-manage-P2P-Connections
A patent Sandvine has:
said by Sandvine Patent Application 20040006643-TCP proxy providing application layer modifications :
[0097] State machine 100 will on occasion need to generate segments, for example when:
- [0098] a) sending ACK segments to the sender to force the sender's rapid re-transmit algorithm to activate;
- [0099] b) sending ACK segments to the sender when entire segments are deleted by application layer analysis module 104; and
- [0100] c) sending RST segments in both directions when the flow is forcibly terminated by application layer analysis module 104.
[0101] This generation of segments is handled by segment generation module 106.
Notice that this is EXACTLY what we're seeing in the wild on Comcast networks.
Comcast and Sandvine, working together to control your internet.
On another note, I've been in contact with Comcast's abuse department. They've told me to find a new ISP if I don't like their practices; so I am.
