Agenda • Background • Motivation • Applications
Background • In the continental U.S., there is a surplus of optical fiber deployed in the ground. • New optical and electronics technology even further extends this “glut” of fiber to amazing bandwidths.
Fiber • In the late ‘90s there was a rush to deploy as much fiber as possible, due to increasing bandwidth demands. • After the dot-com crash, many companies went bankrupt, and fiber was available for pennies on the dollar.
WDM • Also, there were significant advances in Wave Division Multiplexing (WDM). fiber Before WDM
With WDM • Now, many wavelengths (or colors or Lambdas) can be easily ‘mixed’ down one fiber, increasing capacity. fiber
Dense WDM (DWDM) • With DWDM, we now have up to 40 wavelengths per fiber. • Our routing and switching technology current maxes out at 40 gigabits/s (160 lambdas per fiber on the way). 40 gig/s x 40 colors = 1600 gigabit/s/fiber!!
Motivation • With all the cheap fiber in the ground, it seemed like a good idea to buy some (while it is still cheap) and light it up on your own. • But, even though the fiber is cheap (relatively speaking) it is still expensive.
The NLR • Enter, the National Lambda Rail (NLR). • NLR is a U.S. consortium of education institutions and research entities that partnered to build a nation-wide fiber network for research activities. • NLR offers wavelengths to members and/or Ethernet transport services. • NLR is buying a 20-year right-to-use.
NLR Progress • NLR currently has the $80- to $100-million investment to build the entire network. • Using latest optical technologies from Cisco. • Northern tier of network is complete, southern by summer ‘05.

Applications • Pure optical wavelength research • Transport of Research and Education Traffic (like Internet2/Abilene today) • Private Transport of member traffic • Experience working operating and managing an optical network • Development of new technologies (GMPLS) to integrate optical networks into existing legacy networks
The Future • Concepts like the NLR provide wavelengths for members, and wavelengths for pure research. • It is probable that the next-generation Internet2 will ride on the NLR. • NLR provides an AUP-free transport for members.
NASA’s Columbia System • NASA Ames has embarked on a $130-million Linux Super Computer. • Twenty 512 processor IA-64 SGI Altix nodes • NREN-NG: an Optical support WAN • NLR will be the optical transport for this network, delivering high-bandwidth to other NASA centers.
