[Bloat] Another passive bandwidth estimation method

[Michael Menth <menth@uni-tuebingen.de>]

Hi all,

we've recently developed a passive method for finding a link's capacity 
(in a different context). You find the algorithm in III.B.5 in
https://ieeexplore.ieee.org/document/9954450
The approach ist tested in V.B for 1, 10, and 100 Gb/s links on a Linux 
server and provides sufficiently accurate results for bandwidth 
utilizations of 25%. 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.

Kind regards

Michael
