TCPM fixed it in 2001 by providing the flags for ECN, which was enabled by default in Windows since 2012. ALTQ support for ECN has been around for nearly that long. What's changed? Not the TCP reaction (except in extreme cases such as for datacenters) but the router algs. And getting the router algs into routers - esp. home devices. > TCP is also broken in the face of current and within-the-next-year > future wifi technologies.

We've been talking today about how to reduce the ACKs by direct action of the source.
