In particular, the supercomputer community is interested in higher speeds, not just for the interconnection between computers, but as the link between sites.
That's one of the targets for Boston South Network (Bossnet), a long-reach optical network running between Boston and Washington, D.C.
"What they really see supercomputers interconnecting with is 100-Gbit/s Ethernet, so they want to put that on the transmission network," says Ciena's senior VP of strategic planning, Thomas Mock.
Bossnet is considering the move to 100-Gbit/s Ethernet, but, for now at least, the plan is to upgrade the network to 40 Gbit/s early in 2007, a step up from the 10-Gbit/s Ethernet it's using now. Ciena announced this week it's been chosen for that upgrade. (See Ciena Upgrades Bossnet.)
