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 4/27/2020

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 4/27/2020

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 – One a spare  ’s provisioned at outset – One allocated to Internet2 – HOPI project – One an experimental IP network – One a national scale Ethernet 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 4/27/2020

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 4/27/2020

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 4/27/2020

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 4/27/2020

13

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!
