I have not been paying a lot of attention here of late. I objected to
the enormous number of flows goresponsiveness was doing, and strongly

I find 4 flows enough
to stress out a network.

4 flows should often be enough to utilize a network at its full capacity. However, are 4 flows going to provide you stable working conditions in such a way that the bottleneck’s buffers are entirely full over an extended period without fluctuations due to the congestion-response of the individual flows? Also, what is the convergence time to reach stable working conditions and full buffer utilization at 4 flows?

Now, that being said. I don’t think that the exact number of flows is that important. They just need to be enough to fill the buffers in a stable way. All nit-picking on the number of flows just distracts us from actually solving problems on the Internet.

Anyway, is the structure of networkQuality
changing any in ippm?

Yes, the IETF-draft is continuously evolving. You can read the latest version at https://datatracker.ietf.org/doc/html/draft-ietf-ippm-responsiveness.

Discussions around the methodology and the development of the tools as well as addressing issues we find in open-source networking stacks is all happening at the “Network-quality community”, at https://github.com/network-quality/community/wiki. We have a slack-channel and a weekly meeting. Everyone who is actively working on development is invited to join our slack-channel and attend the weekly meetings. (The "active development" is a strong requirement )


Cheers,
Christoph
