I'd like to hear your proposals on how Layer 3 protocols can be better
designed to manage transport characteristics.

It's Layer 1 and Layer 2. Ethernet is running over those optics, albeit
with no "traditional" optical equipment in between.

Under- or over-utilization means different things to different people.
We upgrade at 50% utilization. Others do it at 70% utilization. Others
do it at 100% utilization. Heck, I know some that do it at 40% utilization.
Since not all operations are the same, I can't tell another person what
I think under- or over-utilization is.
