[Bloat] Update to status of Make Wi-Fi Fast page?

[Rich Brown]

Hi folks,

I have been seeing Jim Gettys' post echo around the intertubes. This caused me to look at what we're saying about the Make Wi-Fi Fast project.

The "Current Status" at https://www.bufferbloat.net/projects/make-wifi-fast/wiki/ says:

---
As of early 2017, we have achieved many of these improvements, specifically a decrease of latency by at least an order of magnitude, with fair sharing of air time across fast and slow devices.

• Working software is available in LEDE firmware that runs on off-the-shelf routers, x86 boxes, and embedded systems.
• An academic paper describing the current state of the working software has been submitted for publication; a preprint is available at Ending the Anomaly: Achieving Low Latency and Airtime Fairness in Wifi.
• An earlier recorded presentation and status of the Make Wifi Fast Project
---

Does someone who's close to the work want to update this with any news/more conclusive statements? Thanks.

Rich

Hi

Thanks for the update and for the link to the conference paper.
One short question. Does the WiFi implementation support ECN ?

Hi

Yes, it does (it shares the CoDel code with the fq_codel qdisc). The
WiFi stack turns off ECN marking if the station bandwidth drops below 6
Mbps (as measured by rate control), but otherwise it will ECN mark for
eligible flows instead of drop. :)

Thanks for the prompt reply, good news indeed!.
