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
Typically 1 GE or 10 GE interface, dedicated or non-dedicated 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

5. Infrastructure Update - 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.

7. Infrastructure Update - 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 (

11. 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

12. Infrastructure Update - 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.
