Facilities-based networks
• Regional networks can afford the first
lambda
• Evolution from point solutions (gigapops)
to network solutions (RONs)
• Return to circuit-based systems
– Telco hierarchy -> ATM PVCs -> Light Paths
Why do we want to do this?
• Underlying assumption that big science
needs big performance
• Ever increasing importance of collaboration,
particularly international
• Cost control/avoidance for commodity
services
• Lambda envy
• Scaling

Need full Internet routing, one to many
B. Business applications, multicast, streaming, VPN’s, mostly LAN
Need VPN services and full Internet routing, several to several + uplink
C. Special scientific applications, computing, data grids, virtual-presence
Need very fat pipes, limited multiple Virtual Organizations, few to few

Impact of e-Science and Grids on Networks*
• Several lambda networks being deployed to support growing
demand from eScience
– SURFnet 6, UKlight, NorduLight, Geant 2, NLR, Ultralight, etc
• E-science and grid application have bandwidth needs far exceed that
of production IP networks
• Most entail global collaboration and linkages
• Canadian astronomy – 100 Terabytes per month
• TRIUMF High energy physics – 5 Gbps continuous to CERN
• Canada Light Source synchrotron – 1 to 2 Gbps per beam line
• Ultra video conferencing McGill – 3.5 Gbps
• Hyugens-Cassini eVLBI – 1Gbps
• Merlin UK eVLBI – 320 GBps

The World Is Flat
•
Typical competitors for RON members are not
– Boston, Atlanta, Chicago, Los Angeles, …
•
The competition is global
– Bangalore, Mumbai, Shanghai, Seoul, …
•
Costs of information flow
– are approaching zero
•
Global economic winners will
– have a better trained workforce
– have the ability to participate globally
– be horizontally, not vertically integrated
• nobody is best at everything
So What’s Happening?
• At least 26 RON projects in 40+ states
• Nearly 30,000 miles of fiber collectively
• Providing:
– Internet / Internet2 access
• Peering for R&E and commodity
– Circuits (often gigabit Ethernet)
• Overlay networks
• Lots of learning the stuff the telcos know
– FIT values, TL-1, etc
NLR Infrastructure
• Not a single network but a set of facilities,
capabilities and services to build both
experimental and production networks at various
layers, allowing members to acquire dedicated
(project specific) facilities or shared (community
specific) facilities as appropriate.
