Hybrid Networks
•
Growing use of NLR’s services
• Project uses combination of NLR services to put
together their own network
• Primarily using WaveNet and FrameNet services
• Project picks technology, bandwidth and price to
meet specific project needs
• Can be a scientific application OR another network
service.
•
Expect to see PacketNet used as well.

Hybrid Networks
•
Example - TransitRail
•
•
Network service provided by CENIC and PNWGP
NLR infrastructure used
• TR Backbone
– WaveNet - TR backbone circuits
– FrameNet
» Backup bath for WaveNet circuits
» 1 GE dedicated, burstable above 1Gb if bandwidth is
available
• Access
– FrameNet
» Typically 1 GE or 10 GE interface, dedicated or nondedicated bandwidth VLANs

Hybrid Networks
•
Impact
• Network Diagnosis
• Much harder to diagnose a problem
– What layer
– Who is responsible for the infrastructure in question.
•
NLR support model
– Currently divided by network layer
– Hybrid networks, need someone who is looking at ALL the
layers
•
Network performance
• Similar to network diagnosis
• More components to tune.
• No longer just an IP performance issue

Infrastructure Update - WaveNet
•
WaveNet
• Steady demand for WaveNet services
• NLR has allocated 199 WaveNet Circuits to date
• 126 Active Circuits
– 75 Customer Circuits
– 51 Backbone Circuits (L2, L3, Optical Switch)
• 32 Misc Circuits - spare, unallocated, reserved, SC07
• 41 Decommissioned circuits
– includes SC related circuits, circuits no long in use
by customers, etc.

Infrastructure Update - FrameNet
•
FrameNet
• Demand continues to grow
– 10 GE interfaces and non-dedicated bandwidth are popular
» 7 members with dedicated 10 GE interfaces
• 86 Active VLANs
– Both dedicated and non-dedicated
•
Adding FrameNet connection to MANLAN switch
• Support layer2 connectivity to international networks
•
New map
• Dedicated bandwidth per segment added to the NOC page

Infrastructure - FrameNet
•
Bandwidth on demand project
• Scheduled dedicated bandwidth
– Not real-time, but advanced reservations
• Phased implementation - completed by year end
– Beta testing with the ETF
– Initially fixed endpoint, configured VLAN
» ETF uses as needed, billed according to use
– Phase 2
» Web interface to implement established VLAN
» No access to additional VLAN parameters
– Phase 3
» Web access to VLAN parameter

Infrastructure Update - PacketNet
•
PacketNet
• Adding additional routes
• CIC members have come on-line:
– Indiana, Purdue, MERIT, Wisconsin, Minnesota (1G
only), UIUC, PSU (through Pittsburgh)
•
•
Total routes announced - 8,228
Adding Layer3 backbone circuit between CHIC
and ATLA.

SC07
•
•
Infrastructure
• 2 10 GE FrameNet, 2 10 GE PacketNet
• Providing C-band transponders for CA to NV link,
but no other Layer1 circuits
Applications • 21 requests to date for NLR connectivity
• Includes 3 International requests
•
Many members using PacketNet as the default
connectivity for SC07.
• No need to submit connectivity request.
