Very interesting, thank you. So great you have code on github!

I appreciate the mention of cake, and I figure it would scale worse
than fq-pie in the 100Gbit scenario you present, but do not know.
However, it does come with a built in forground (respecting EF, and a
few other diffserv codepoints), and a background service class,
respecting both CS1 and LE, and it would be interesting to know how
that differs from DSCD?

The method is likely to work also for lower utilizations, but this was not an issue in this work. The method is applicable only by a link's head-end node. It does not work for end systems to find the bottleneck bandwidth on some unknown intermediate node. However, it can deliver useful information for scheduling algorithms in forwarding nodes, which is the use case in this paper, and which may be of interest to some readers on this list.
