Level 3's projections for 2010 show that some edge connections will require 60 lines of link-aggregated 10-Gbit/s Ethernet, and some intranode and backbone connections will use 150 aggregated lines.
"We really see 100-Gbit/s Ethernet leapfrogging 40 Gbit/s as for transport going forward," if only because of the scale the network will demand, Tench says.
Unlike Verizon Communications Inc. (NYSE: VZ), Level 3 isn't asking for 100 Gbit/s right now, but Tench hammered on the need for 100 Gbit/s multiple times. (See Verizon Gears Up for 100 Gig.)
Leftover from Day 1, there's a sound bite from yesterday's keynote by Steve Alexander, CTO with Ciena Corp. (NYSE: CIEN):
The problem we all made ourselves into with the 40-Gbit/s world is that we made it a photonics problem and an electronics problem at the same time... The approach the vast majority of people are taking at 100 Gbit/s is to not turn it into an electronics problem.
So, for folks anxious for 100-Gbit/s Ethernet, the wait could have been worse. (See 100-GigE Not Coming Soon Enough.)
