  1. Next Generation Abilene Internet2 Member Meeting Washington DC

  2. Partnership approach • The Abilene Network is a UCAID project done in partnership with • Cisco Systems (routers, switches, and access) • Juniper Networks (routers) • Nortel Networks (SONET kit) • Qwest Communications (SONET & DWDM circuits) • Indiana University (network operations center) • Internet2 Test & Evaluation Centers (ITECs) • North Carolina and Ohio

  3. Abilene – May, 2002 • IP-over-SONET backbone (OC-48c, 2.5 Gbps) 53 direct connections • 4 OC-48c connections • 1 Gigabit Ethernet trial • 23 will connect via at least OC-12c (622 Mbps) by 1Q02 • Number of ATM connections decreasing • 215 participants – research universities & labs • All 50 states, District of Columbia, & Puerto Rico • 15 regional GigaPoPs support ~70% of participants • Expanded access • 50 sponsored participants • New: Smithsonian Institution, Arecibo Radio Telescope • 23 state education networks (SEGPs)

  4. Packetized raw High Definition Television (HDTV) • Raw HDTV/IP – single UDP flow of 1.5 Gbps • Project of USC/ISIe, Tektronix, & U. of Wash (DARPA) • 6 Jan 2002: Seattle to Washington DC via Abilene • Single flow utilized 60% of backbone bandwidth • 18 hours: no packets lost, 15 resequencing episodes • End-to-end network performance (includes P/NW & MAX GigaPoPs) • Loss: <0.8 ppb (90% c.l.) • Reordering: 5 ppb • Transcontinental 1-Gbps TCP requires loss of • <30 ppb (1.5 KB frames) • <1 ppm (9KB jumbo)

  5. End-to-End Performance:‘High bandwidth is not enough’ • Bulk TCP flows (transfers > 10 Mbytes) • Current median flow rate over Abilene: 1.9 Mbps • 95th percentile: 7.0 Mbps

  6. Future of Abilene • Original UCAID/Qwest agreement amended on October 1, 2001 • Extension of MoU for another 5 years – until October, 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

  7. Key new aspects of next generation Abilene backbone • High-performance IPv6 – next generation • Run natively - concurrent with IPv4 • Replicate multicast deployment strategy • Close collaboration with Internet2 IPv6 WG • Enhanced, differentiated measurement capabilities • Active measurement: periodic network probes (incl. flows) • Passive measurement: traffic matrix, SNMP, & routing Computer science research via ‘Abilene Observatories’ • End-to-End Performance beacons • Network resiliency • Abilene ’s will not be protected circuits as with SONET • Need restoration times under 100 ms – VoIP & videoconf

  8. Next generation router selection • Extensive router specification and test plan developed • Team effort: UCAID staff, NOC, NC and Ohio ITECs • Discussions with four router vendors • Tests focused on next gen advanced services • High performance TCP/IP throughput • High performance multicast • IPv6 functionality & throughput • Classification for QoS and measurement • 3 router platforms tested & commercial ISPs referenced •  New Juniper T640 platform selected

  9. Optical networking scaling factors • 2 TeraGrid routing nodes • 11 Next Generation Abilene routers • 53 Abilene connectors • 215 Abilene participants (univs & labs) • But… • 30-60 DWDM access nodes in leading viable carriers’ U.S. networks

  10. Regional optical fanout • Next generation architecture: Regional & state based optical networking projects are critical • Three-level hierarchy: Backbones, GigaPoPs, campuses • Leading examples • CENIC ONI (California), I-WIRE (Illinois), I-LIGHT (Indiana) • State-based projects can be viewed as cost sharing • Collaboration with the Quilt • Regional Optical Networking project • Interface with next generation Abilene and future projects • U.S. carrier DWDM access is not widespread • 30-60 cities for DWDM now • ~120 cities for SONET (circa 1998) • Further expansion constrained by current telecom crunch

  11. Optical network project differentiation

  12. Conclusions – Abilene future • Backbone upgrade project underway • Partnership with Qwest extended thru 2006 • Juniper T640 routers selected for backbone • 10-Gbps backbone  deployment starts this fall • Advanced service foci • Native, high-performance IPv6 • Enhanced, differentiated measurement • Network resiliency • Incremental, non-disruptive transition • Complementary to and collaborative with NSF’s TeraGrid
