  1. Abilene and U.S. advanced regional networking update Steve Corbató Director, Backbone Network Infrastructure Pacific Rim Networking Honolulu 21 February 2002

  2. Abilene focus • Goals • Enable innovative applications and advanced services not possible over the commercial Internet through a high-performance IP common bearer service • Advanced national & regional infrastructure provides a vital substrate for the continuing culture of Internet advancement in the university/non-profit/corporate research sectors • Advanced service efforts • Multicast • IPv6 • QoS • Measurement • Security

  3. Abilene background & milestones • Abilene is a UCAID project in partnership with • Qwest Communications (SONET & soon DWDM service) • Nortel Networks (SONET kit provider to Qwest) • Cisco Systems (routers) • Indiana University (network operations) • ITECs in North Carolina and Ohio (test and evaluation) • Timeline • Apr 1998: Project announced at White House • Jan 1999: Production status for network • Oct 1999: IP version of HDTV (215 Mbps) over Abilene • Apr 2001: First state education network added • Jun 2001: Participation reaches all 50 states & D.C. • Nov 2001: Raw HDTV/IP (1.5 Gbps) over Abilene

  4. Abilene – February, 2002 • IP-over-SONET (OC-48c) backbone • 53 direct connections • 3 OC-48c connections - NCNI will be the 4th • 1 Gigabit Ethernet trial - MREN • 23 will connect via at least OC-12c (622 Mbps) by 1Q02 • Number of ATM connections decreasing • 207 participants – research universities & labs • All 50 states, District of Columbia, & Puerto Rico • 15 regional GigaPoPs support ~70% of participants • Expanded access • 37 sponsored participants • 19 state education networks (SEGPs) • including Hawai`i, California, Oregon, & Washington

  6. Abilene & High Performance Computing • Backbone MTU raised to 9K bytes • Connector & peer MTUs changed on per request basis • SCxy effort part of ongoing HPC support • Annually escalating bandwidth • SC99 Portland: OC-12c SONET (622 Mbps) • SC2000 Dallas: OC-48c SONET (2.5 Gbps) • SC2001 Denver: 2xOC-48c SONET (5 Gbps) • Significant traffic engineering • SC2002 Baltimore: 10-Gbps  (planned) • transit for domestic & international R&E peer networks • End-to-End Performance: GigaTCP testing

  7. Raw HDTV/IP testing • Packetized raw HDTV (1.5 Gbps) • ISIe, Tektronix, & UW project/DARPA support • Connectivity and testing support • P/NW & MAX Gigapops, Abilene and DARPA Supernet, Level(3) • SC2001 public demo • November, 2001 • SEA -> DEN via L(3) OC-48c SONET

  8. Implications for support of high performance flows over Abilene • DARPA PIs Meeting: SEA->DC area 1/6/02 • P/NW, Abilene, & MAX in Internet2 path • 18 hrs of continuous, single-stream raw HD/IP • UDP jumbo frames: 4444 B packet size • Application level measurement • 3 billion packets transmitted • 0 packets lost, 15 resequencing episodes • e2e network performance • Loss: <8x10 -10 (90% confidence level) • Reordering: 5x10 –9 • Transcontinental 1-Gbps TCP (std 1.5 kB MTU) requires loss at the level of 3x10 –8 or lower

  9. Future of Abilene • Original UCAID/Qwest MoU amended on October 1, 2001 • Extension of Qwest’s original commitment to Abilene for another 5 years – 10/01/2006 • Originally expired March, 2003 • Upgrade of Abilene backbone to optical transport capability - ’s (unprotected) • x4 increase in the core backbone bandwidth • OC-48c SONET (2.5 Gbps) to 10-Gbps DWDM • Capability for flexible provisioning of ’s to support future point-to-point experimentation & other projects

  10. Key aspects of next generation Abilene backbone - I • Native IPv6 • Motivations • Resolving IPv4 address exhaustion issues • Preservation of the original End-to-End Architecture model • p2p collaboration tools, reverse trend to CO-centrism • International collaboration • Router and host OS capabilities • Run natively - concurrent with IPv4 • Replicate multicast deployment strategy • Close collaboration with Internet2 IPv6 Working Group on regional and campus v6 rollout • Addressing architecture

  11. Key aspects of next generation Abilene backbone - II • Network resiliency • Abilene ’s will not be protected like SONET • Increasing use of videoconferencing/VoIP impose tighter restoration requirements (<100 ms) • Options: • Currently: MPLS/TE fast reroute • IP-based IGP fast convergence (preferable) • Addition of new measurement capabilities • Enhance active probing (Surveyor) • Latency & jitter, loss, TCP throughput • Add passive measurement taps • Support for computer science research – “Abilene Observatories” • Support of Internet2 End-to-End Performance Initiative • Intermediate performance beacons

  12. Manhattan Landing – an emerging New York City exchange point • MAN LAN is a project initiated to meet the needs of our international peers in NYC • Abilene ITN does not provide transit to the U.S. fed nets • MAN LAN is an I2 effort - not part of the Abilene Network • NYC analog to Pacific Wave and STAR LIGHT EPs • designed to integrate closely with the GTRN effort • Gigabit/10-Gigabit Ethernet switch for bilateral peerings between U.S. and int’l research nets • Cisco 6509 NEBS-compliant switch at 60 Hudson St, 23rd fl • NG Abilene will connect at 10-Gbps – summer, 2002 • Partnership • IEEAF, Indiana University, NYSERNET, CANARIE • Project point: Paul Love <epl@internet2.edu>

  13. Regional optical fanout • Next generation architecture: Regional & state based optical networking projects are critical • three-level hierarchy: Backbone, GigaPoPs/ARNs, campuses • Leading examples • CENIC ONI (California), I-WIRE (Illinois), • SURA Crossroads (Southeastern U.S), I-LIGHT (Indiana) • Collaboration with the Quilt • Regional Optical Networking project • U.S. carrier DWDM access is now not nearly as widespread as with SONET circa 1998

  14. Optical network project differentiation

  15. The ‘Big Hybrid Build’: A national fiber optical networking facility • Objective: • To create an extensible, multi- national facility – O(100) Gbps - to support the diverse and evolving advanced networking requirements of the U.S. scientific communities, research universities, and advanced regional networks

  16. Building a national fiber optical networking facility • Purchase IRUs for 1-2 pairs of fiber on national footprint (12-20 access points) • Leverage current fiber glut and turbulent corporate climate • 2nd pair would enable optical experimentation and eventual upgrade transition • Pursue condominium approach to O&M (corporate partner) • Multiple ’s for multiple uses – IP bearer service, p2p ’s • ‘N-body’ academic/corporate partnership • National fiber builder and O&M provider • Optical transport kit producer • Need next generation ULH gear? • Optical switching partner (when ready) • ‘Optically enabled’ advanced regional networks for fanout and vital optical technology collaboration

  17. Conclusions • Abilene future • UCAID’s partnership with Qwest extended through 2006 • Backbone to be upgraded to 10-Gbps in three phases • Native v6, enhanced measurement, and increased resiliency are new thrusts • Overall approach to the new technical design and business model is for an incremental, non-disruptive transition • Nicely positioned and collaborative with NSF’s TeraGrid distributed computational backplane effort • {Pacific  National} Light Rail • Emerging & expanding collaboration to develop a persistent advanced optical network infrastructure capability to serve the diverse needs of the U.S. higher ed & research communities • Initial partners: CENIC & P/NW, Argonne/TeraGrid, UCAID
