[$] The congestion-notification conflict
Most of the time, the dreary work of writing protocol standards at
organizations like the IETF and beyond happens in the background, with most
of us being blissfully unaware of what is happening. Recently, though, a
disagreement over protocols for congestion notification and latency
reduction has come to a head in a somewhat messy conflict. The outcome of
this discussion may well affect how well the Internet of the future works —
and whether Linux systems can remain first-class citizens of that net.
