Abilene Status

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

5
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.

6
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

7
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 SVL- Sacramento (SAC) ELH
route will become part of NLR SVL-SEA in exchange
for a SVL-SAC LH route NLR is building (not shown
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
  RE Networks
• Addition of Cisco 15454 to support experimental
  projects such as the GLIF. Current connectors
• CAnet
• Abilene
• Surfnet
• Some near term tests Lightpath consisting of a
  variety of technologies crossing multiple
  administrative domains will discuss more fully
  later

• Connecticut (Connecticut Education Network)
• Florida (Florida LambdaRail)
• Indiana (I-LIGHT)
• Illinois (I-WIRE)
• Maryland, D.C. northern Virginia (MAX)
• Michigan
• Minnesota

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

13
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

14
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!
