QuoteRecently, it has been observed that Comcast is disrupting TCP connections using forged TCP reset (RST) packets . These reset packets were originally targeted at TCP connections associated with the BitTorrent file-sharing protocol. However, Comcast has stated that they are transitioning to a more "protocol neutral" traffic shaping approach . We have recently observed this shift in policy, and have collected network traffic traces to demonstrate the behavior of their traffic shaping. In particular, we are able (during peak usage times) to synthetically generate a relatively large number of TCP reset packets aimed at any new TCP connection regardless of the application-level protocol. Surprisingly, this traffic shaping even disrupts normal web browsing and e-mail applications. Specifically, we observe two different types of packet forgery and packets being discarded.
