I think you're doing good work, but I'm concerned you're going down
a road that's going to take a very long time to get right. It is not
necessary to calculate the bandwidth*delay in order to prevent over-
buffering. Preventing overbuffering only requires tracking the maximum
bandwidth*delay value, assuming that we always want the ability to
buffer that much data. I think the number of cases where it decreases
significantly over the peak for a long enough time to make a difference
is minimal.
Fully knowing the value over time could lead to optimizations like
shrinking the buffers, or attempting to prevent some packet loss by
not over-increasing the window. However oscellation and other issues
I think are going to make this very complex.
