The preprint is available at: https://arxiv.org/abs/2206.06642 I thought that it could provoke an interesting discussion in this group. Figures 4 and 5 in this paper show that, across the world, network links do not just become "faster=E2=80=9D: the range between the low end an= d the high end grows too. This, I think, is problematic for a global end-to-end standard - e.g., it means that we cannot simply keep scaling IW along forever (or, if we do, utilization will decline more and more). So, we ask: what is the way ahead? Should congestion control really stay end-to-end?
