Internet2 Network Infrastructure: Abilene Current Status and Future Plans Rick Summerhill Associate Director, Backbone Network Infrastructure, Internet2 GNEW 2004 Meeting CERN, Geneva, Switzerland March 15, 2004 This is a general overview presentation about Internet2. Internet2 is a consortium, led by US universities, which is recreating the partnership among academia, industry and government that fostered today’s Internet in its infancy.

Abilene Status 11/20/2018

Abilene Status Participation Peering 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 11/20/2018

Abilene Status Performance Timeframe 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. 11/20/2018

Abilene Status Experimentation Research 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 11/20/2018

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? 11/20/2018

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 11/20/2018

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). 11/20/2018

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 11/20/2018

Leading & Emerging Regional Optical Initiatives California (CALREN) Colorado (FRGP/BRAN) Connecticut (Connecticut Education Network) Florida (Florida LambdaRail) Indiana (I-LIGHT) Illinois (I-WIRE) Maryland, D.C. & northern Virginia (MAX) Michigan Minnesota New York + New England region (NEREN) North Carolina (NC LambdaRail) Ohio (Third Frontier Network) Oregon Rhode Island (OSHEAN) SURA Crossroads (southeastern U.S.) Texas Utah Wisconsin 11/20/2018

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 11/20/2018

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 11/20/2018

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! 11/20/2018
