<div dir="ltr"><div>Hello from Canada,</div><div>I noticed some discussion about FCC and latency again (here and on hacker news: <a href="https://news.ycombinator.com/item?id=39533800">https://news.ycombinator.com/item?id=39533800</a>). A few years ago, Reza and I spent considerable work at our national regulator, CRTC, establishing a latency and packet loss threshold for a minimum service broadband. We used M-Lab data to do so and I always hoped to see more work on latency as a measure, especially because you can calculate what would be minimum theoretical latency from an off-net IXP to a home.</div><div><br></div><div>You can see some of our work here: <a href="https://www.tandfonline.com/doi/pdf/10.1080/01972243.2019.1574533">https://www.tandfonline.com/doi/pdf/10.1080/01972243.2019.1574533</a> & <a href="https://crtc.gc.ca/public/cisc/nt/NTRE061.pdf">https://crtc.gc.ca/public/cisc/nt/NTRE061.pdf</a></div><div><br></div><div>The final decision: <a href="https://crtc.gc.ca/eng/archive/2020/2020-408.htm">https://crtc.gc.ca/eng/archive/2020/2020-408.htm</a></div><div><br></div><div>Happy to offer any advice here and share some experiences if that helps.</div><div><br></div><div>Be good,</div><div>Fenwick<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 27 Feb 2024 at 13:32, 'rjmcmahon' via discuss <<a href="mailto:discuss@measurementlab.net">discuss@measurementlab.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Thanks for sharing this. I'm trying to find out what are the key metrics <br>
that will be used for this monitoring. I want to make sure iperf 2 can <br>
cover the technical, traffic related ones that make sense to a skilled <br>
network operator, including a WiFi BSS manager. I didn't read all 327 <br>
pages though, from what I did read, I didn't see anything obvious. I <br>
assume these types of KPIs may be in reference docs or something.<br>
<br>
Thanks in advance for any help on this.<br>
