I think it will be critically important, especially in long-haul
Historically speaking, as providers have replaced congested links
with faster ones, they have also become quickly congested. And since
these high-speed long-haul links are not cheap, you can bet that these
organizations want to get the most bang-for-the-buck. I can't imagine
that ~25% bandwidth overhead would be acceptable, especially when
more efficient alternatives exist.
Nice synopsis, Jim.
