Thanks for your response and also thanks for the ANRW'21 paper and talk 
[1]. Especially the referenced papers are very interesting for a 
satellite use-case. As I see it, "multi-domain congestion control" is 
closely related to our idea of "path-wise congestion control".
Are there any updates regarding performance evaluation results and/or 
publicly available implementations in this context? (sorry in case I 
missed it on the lists)
