I am likely out of date about Windows Update, but there's many other programs that do background downloads or uploads that don't implement LEDBAT or similar protection. The current AQM recommendation draft in the IETF will make things worse, by not drawing attention to the fact that implementing AQM without implementing a low priority traffic class (such as DSCP 8 - CS1) will prevent solutions like LEDBAT from working, or there being any alternative. Would appreciate support on the AQM list in the importance of this.
