Measurement Lab is hosting a community discussion panel about measuring
bufferbloat at scale, and related topics.   This will be an open discussion
- the audience will be able to ask questions and make comments, within
our community
guidelines <https://www.measurementlab.net/community-guidelines/>.

11a ET, 8a PT, Wednesday, August 25.

Please register

Subject: [M-Lab-Discuss] Latency, Bufferbloat, Responsiveness & Internet
Quality - discussion (next) Wednesday, August 25
To: <discuss at measurementlab.net>

Internet performance is often measured by download and upload “speed” but
there are other metrics that can help measure connectivity, such as
latency, bufferbloat and a more recently discussed metric: responsiveness. Join
us next Wednesday, August 25, 2021 from 11am-12:30pm Eastern for a
conversation with Internet Measurement researchers with expertise and
interest in each of these metrics including:

Matt Mathis, Senior Research Scientist, Measurement Lab, Google

Matt Mathis has been working on Internet performance research and
development since 1990.  His work includes measurement tools, models and
improvements to protocol standards.  He participated in MLab from its
inception in 2009, and came to Google in 2010 to find a larger platform on
which to stand.

Dave Taht

Dave Taht and members of the Bufferbloat Project
<https://www.bufferbloat.net/projects/>have made vast improvements to the
Internet and to WiFi, as described in the book, “Bufferbloat and Beyond
<https://blog.tohojo.dk/media/bufferbloat-and-beyond.pdf>”. He has lectured
at Stanford and MIT, NANOG, RIPE, USENIX, IEEE, and the IETF. His R&D work
on AQM/FQ technologies on the Internet have been integrated into the Linux,
OSX, and IOS kernels, cable modems, and many WiFi chips, and he has created
and managed Internet improvement initiatives such as CeroWrt, make-wifi-fast
<https://lwn.net/Articles/705884/>, cake, and more. From these projects we
have seen major innovations in congestion control algorithms such as BQL,
FQ_codel, FQ_pie, and BBR.

Christoph Paasch, Networking Architect, Apple

Christoph Paasch has been working on transport layer networking since 2010.
Focusing on extensions to TCP, like Multipath TCP or TCP Fast Open. From
specification (in the case of MPTCP) and research to the implementation and
large scale deployments at Apple. Lately he has shifted his focus on
improving the network properties that really matter to the end-user
experience by exposing measurement tools to raise awareness to these
issues. "Responsiveness under working conditions" being now the first
primary target.

The conversation will be moderated by Lai Yi Ohlsen, Director of
Measurement Lab, a fiscally sponsored project of Code for Science &

Our casual conversation will include discussion about the significance of
these metrics as well as the challenges their collection presents. We
welcome audience questions, answers, challenges, and discussion. The
discussion will be technical but no familiarity with M-Lab is required; all
we ask is that participants review and respect our community guidelines

If you have previously RSVP’d to our community calls, you should have
already received a calendar invite with a Zoom link included. If not,
please reply directly to this email.

If you have not previously RSVP’d, but would like to attend, please do so
and indicate that you’d like to be attended to the “Internet Research”
meetings. You’ll be sent a Zoom link shortly after.

Please note that our conversation will be recorded. If you attend, you will
be asked to give your consent to being recorded. The recording will be
published and distributed openly.

If you have any questions, please feel free to reply to this email directly
or write to laiyi at measurementlab.net.
