Neither. I'm reporting the state of the science having been engrossed
in its research for the better part of a decade. Places like the IRTF
RRG. Because no science, also no tech. If you think have some magic
new algorithm that the RRG didn't consider, feel free to explain it
and I'll demonstrate a scenario for you where it fails too.

And I tip my hat to the router vendors for declining to implement
knobs which would damage the network, despite the demands of Randy
