Subject: Passive RTT Measurement / Middlebox discussion

In Prague, we discussed passive RTT measurement.

Issue: https://github.com/quicwg/base-drafts/issues/631
Draft minutes: https://github.com/quicwg/wg-materials/blob/master/ietf99/minutes.md#passive-rtt-measurement-in-quic---ian-swett

The outcome of that discussion was the formation of a Design Team, led by Ted Hardie, to review what privacy risks would be eliminated if this information is not available and to ascertain what network measurement and management options would be available if this information is not.

We expect them to report back in the Singapore meeting.

In the meantime, please refrain from discussing passive RTT measurement on-list. We'd also appreciate it if related issues (e.g., #632, on-path calculation of loss and congestion) was also deferred until we see those results.

We believe that the design team's membership is representative of both operators' needs and privacy concerns. If you'd like to contribute, please contact Ted, but please understand that to be successful, the team's size needs to be limited. Ted will post the team's membership to the list shortly.

See <https://www.ietf.org/iesg/statement/design-team.html> for more information about Design Teams in the IETF.

Thanks,
