So far as I am aware there is not even a completed prototype implementation of L4S. And in slide 4 "Standardized in IETF [1]" is a premature statement about the actual state of the L4S drafts. In slide 5, the graphs, what are the blue line and the red line? Are they simply 2 identical flow attempts? Also no data on this graph about B or D values, though I can speculate it is 250mb/s and 25 ms, but that falls out when I look at the L4S forwad packet delay graph as the delay there is below that of my 25mS derived D, which could not occur. Could you please provide a description of the tooling data, and parameters so that we might independently validate these graphs?
