NLR Engineering Committee
• Advises NLR’s President/CEO and Director
of Development and Operations on
technical aspects of NLR Architecture and
Equipment
• Composed of technical representatives from
NLR Member Institutions
• Currently reviewing final design on:
– Layer 2 hardware configurations
– Layer 3 hardware selection and configuration
• Meets through weekly conference calls
• In person meetings as necessary

Peeling back the layers of NLR
• NLR is multiple infrastructures/networks
• Layer 1 Optical Infrastructure
– 10 Gig lambdas (10 GE LANPHY or OC-192)
– Wavelengths are non-diverse, may support
experiments, but are offered as production
• Layer 2 GigE Network
– GigE client ports
– May support experiments, operated as production
service
• Layer 3 IP Network
– 10 GE port for each NLR member
– Experimental network

Layer 1 - Optical Infrastructure
• Phase 1 - Uses Cisco 15808 DWDM gear
– Capable of 40 10GE or OC-192 channels
– San Diego to Los Angeles, Sunnyvale via CENIC
– Sunnyvale to Portland, Seattle, Denver, Kansas City, Chicago,
Pittsburgh, Washington DC, Raleigh, Atlanta and Jacksonville
• Phase 2 - Planning for Cisco 15454 MSTP
– Capable of 32 10GE or OC-192 channels
– Jacksonville to Pensacola, Baton Rouge, Houston, San
Antonio, El Paso, Phoenix, Los Angeles and Washington DC to
New York, Cleveland
– Alternate N/S paths, Houston to Kansas City and El Paso to
Denver

Located at major NLR Points of Presence
Interconnected with 10GE trunks
Provides GE interfaces to user
Production level service (may be used to support experiments)
NLR will provide 7x24 support for Gig-E transport service
Will be pre-production at startup
• To determine what it means to operate coast-to-coast Ethernet
• To understand how to provide guaranteed Gig-E transport using
Layer 2

Sparsely located at NLR Points of Presence
Interconnected with diverse path 10GE trunks
10GE ports for NLR member network connections
Used to support network experimentation
Work closely with Cisco to leverage features and capabilities of
CSR to support experimentation and research

Connecting to NLR
• Must come to NLR “MetaPOP”
– Suite/colo in fiber provider POP (e.g. Level3)
• Can bring permanent fiber into the NLR suite
– Examples: PNWGP in Seattle
– Southern LambdaRail (SLR), aka Georgia Tech in
Atlanta
• Or simple fiber cross-connect
