Shepherd writeup
rfc8382-11

1. Summary

The document shepherd is Anna Brunstrom (anna.brunstrom@kau.se)
The responsible Area Director is Mirja Kuehlewind (ietf@kuehlewind.net)

   This document describes a mechanism to detect whether end-to-end data
   flows share a common bottleneck.  It relies on summary statistics
   that are calculated based on continuous measurements and used as
   input to a grouping algorithm that runs wherever the knowledge is
   needed.  This mechanism complements the coupled congestion control
   mechanism in draft-ietf-rmcat-coupled-cc.

2. Review and Consensus

The draft has been under development in the RMCAT WG for some years, receiving several rounds of reviews. There seems general, but not overwhelming, consensus from the working group that the mechanism is useful and suitable for use together with coupled congestion control. There has been no controversial points.

4. Other Points

This document is experimental, as a number of algorithm parameters have to be tested under real network conditions, see Section 6 "Expected feedback from experiments". The current set of parameters have been mainly evaluated through simulation. The WG will collect the feedback from first experiments using SBD and use them to discuss further steps.
