Agenda
• Background
• Motivation
• Applications
3
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.
4
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.
5
WDM
• Also, there were significant advances in Wave Division Multiplexing (WDM).

Before WDM
6
With WDM• Now, many wavelengths (or colors or Lambdas) can
be easily ‘mixed’ down one fiber, increasing capacity.

7
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!!
8
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.
9
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.
10
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.

15
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
16
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.
17
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.
