Re: Comcast is using Sandvine to manage P2P Connectionssaid 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.
