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? > Kind regards > > Michael > > > Am 01.08.2023 um 09:51 schrieb Sebastian Moeller: > > Hi Michael, > > > > that "teaser" you wrote is certainly interesting.

The method is likely to work also for lower utilizations, but t= his 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 ba= ndwidth on some unknown intermediate node.
