Infrastructure - Network of networks
• Fiber based, optical network
• Owned and operated by NLR
• National fiber footprint
• Production and experimental networks over the same
infrastructure.
• Building blocks
• Phase 1: Northern footprint
– Supports up to 40 lambdas on each segment
•
Phase 2: Southern footprint
– Up to 32 lambdas on each segment
•
Provides flexibility to meet the needs of the user community.
• Core services at Layer1, Layer2 and Layer3

•
Dedicated Bandwidth
• Guaranteed bandwidth - increments of 100Mbps
• Additional backbone links are added if dedicated bandwidth
exceeds 6 Gbps.
• Pricing is distance sensitive
• Redundancy is available upon request
•
Non-Dedicated
• No cost through 12/07 for bandwidth
• Minimal cost for additional ports

FrameNet Services - Example Uses
•
Backup Connectivity
• Dedicated or non-dedicated VLAN between two RONS
• 3ROX (Pittsburgh) to SOX (Atlanta) - regional peering and
backup Abilene connectivity
•
FLR
• BATO to JACK - the long way (through Chicago)
– Backup to regional connectivity
•
•
Project Infrastructure
• VINI - 6 site multi-point. Test-bed overlay connecting VINI
platforms.
Collaboration

PacketNet
•
Designed to be extremely reliable
• Diverse backbone
• Redundant route processors, power supplies
• Redundant member connections
• 10 GE primary connection
• 1 GE backup connection
• Backup connection opposite direction and connects to
different router
Takes multiple failures to cause a backbone or
end-site outage
PacketNet routes
• 7212 distinct routes
•
