Abilene Status
Participation
• University participation continues to be strong!
• Decrease in number of connectors
– Connector upgrades of bandwidth
– Increase in aggregation
– Evolution of GigaPoPs to RONs (Regional Optical Networks)
Peering
• Peering between Abilene and other International networks
has continues to grow – Abilene ITN
• Upgrade of peering with ESnet to OC-48 minimum
• Increase in the number of experiments looking to the future to alternative architectures and means of connectivity

Abilene Status
Performance
• 5.6 gbps flow across Abilene – CalTech to CERN during
Indianapolis Internet2 Member Meeting
• 6.25 gbps streams during March – CalTech to CERN
• Consistent 9 gbps traffic flows to/from Abilene during
SC2003 in Phoenix
• The Performance is Good, but we need to look to the future
Timeframe
• Current agreement with Qwest runs till October 2006
• Roughly one and half years to determine what is next.

Abilene Status
Experimentation
• MPLS is a convenient tool for now
• Use of MPLS tunnels to emulate circuits for
TeraGrid participants
– PSC – was a L3 MPLS tunnel
– Texas – to be a L2 MPLS tunnel, to be determined
• MPLS tunnel to support experiments between our
ITECs and the Abilene NOC
Research
• Abilene Observatory – approximately 20 research
projects using observatory data

Problems Today
Given the current technology, Abilene is a
productive and viable shared packet
Infrastructure. However, …
Some discipline specific networks have
enormous bandwidth requirements, e.g.,
• High Energy Physics Community
• The Radio Astronomy Community
Problems with packet infrastructures
•
•
•
•
Perceived problems with shared packet infrastructures?
Will we have 40 gbps or 100 gbps in near future?
Increasing demands by some for deterministic paths?
Demand on future networks for more dynamic control of
bandwidth and topology?
• Service oriented networks?

NLR Summary
 US higher-ed owned and managed optical networking &
research facility
•
•
~10,000 route-miles of dark fiber
Four 10-Gbps ’s provisioned at outset
–
–
–
–
One allocated to Internet2 – HOPI project
One an experimental IP network
One a national scale Ethernet
One a spare
 Connectivity between the experimental IP network and Abilene
will be on a limited basis – much like the TeraGrid and Darpa
experimental connections.
 An experimental platform for network research
•
•
Research committee integral in NLR governance
Experimental support center
 Waves to be in place by late August – in particular, the
Internet2 wave for the HOPI project

Note: California (SAN-LAX-SVL) routes shown are part of CalREN; NLR is adding waves to CalREN systems. Also the CENIC SVLSacramento (SAC) ELH route will become part of NLR SVL-SEA in exchange for a SVL-SAC LH route NLR is building
(not shown
9 here).

Internet2 GLIF Participation
Global Lambda Integration Facility
Internet2 Participation
• MAN LAN Experimental Facility
• TYCO/IEEAF Circuit shared between Internet2 and SURFNET –
10 Gig wave between NYC and Amsterdam
MAN LAN Exchange Point
• MANLAN Proper is an Ethernet Exchange Point for R&E
Networks
• Addition of Cisco 15454 to support experimental projects such as
the GLIF. Current connectors:
– CA*net
– Abilene
– Surfnet
Some near term tests: Lightpath consisting of a
variety of technologies crossing multiple
administrative domains – will discuss more fully later

Looking to the Future
Problems to understand
•
•
•
•
Future architectures
Temporal degree of dynamic provisioning
Topological extent of deterministic provisioning
Examine backbone, RON, campus hierarchy – how will a
RON interface with the core network?
• Understand connectivity to other infrastructures – for
example, international or federal networks?
• Network operations, management and measurement
across administrative domains?
Resources – Abilene, NLR Wave, MAN LAN,
RONs
HOPI Project – Linda Winkler will talk on this
later

Transatlantic Lightpath Experiment
Grew out of a meeting in December with
CANARIE, GEANT and Internet2
Decided to setup a basic 1 Gig Lightpath to
demonstrate technologies and requirements
• Followed KIDS, not KISS – that is, keep it difficult stupid! -
• Uses a variety of layer 1, 2, and 3 technologies
• Crosses administrative domains using different layers
Goal - examine the problems, and how one
might make this dynamic (in some way)!
Control Plane
• 8 hours of conference calls
• Approximately 300 pieces of email

Lightpaths
 A lightpath is a virtual private or dedicated
unidirectional path with a given service level
guarantee (i.e., deterministic behavior)
•
•
•
•
Extremely low jitter
Close to light speed latency behavior in glass
Guaranteed bandwidth
Extremely low packet loss
 Examples
•
•
•
•
•
WDM
TDM
MPLS based techniques (including L2VPN and use of CCC)
Premium IP Service
ATM CBR PVC
 Any concatenation of two lightpaths should be a
lightpath – lightpaths can be joined end-to-end!
