This reminds of QoS in trying to find a solution for a particular mode of
usage within a given network capacity. What is missing is any hint of
increasing capacity and that may be a serious limitation in Comcast's view
of the world. It's acting as if Bit Torrent is the problem rather than being
a symptom of the inability to second-guess application needs.

Dave -

For IP if you wish.

I talked to Comcast's CTO, Tony Werner, on the enhancements to their
traffic shaping system they announced today. In a nutshell, they're
going to stop application-centric RST injection, and use the scheduling
mechanism in the DOCSIS CMTS instead. I've done a blog post on it:

IETF purists should rejoice, of course.

Cheers,
