Abilene Update Joint Techs Summer ’05 Vancouver, CA Steve Cotter Director, Network Services [email protected] Welcome • Current Abilene Network • Advanced Networking Services Offered • Abilene Network Futures 2 The Abilene Network Abilene Partnerships • • • • • Indiana University Juniper Networks Nortel Networks Qwest Communications ITECs • • • • NC ITEC Ohio ITEC San Diego ITEC Texas ITEC • Internet2 4 Abilene Overview • 10-Gbps ‘best effort’, over-provisioned IP network • Current normal load ~2 Gbps; ~10 Gbps peak • Carrier provisioned backbone λ’s (Q-Wave) • ~4.7 9’s availability over past 12 months • SONET backhaul available to connectors • IPv4/IPv6, native multicast, MPLS LSPs • Network research facilitation (data + co-lo) • Abilene Observatory project • Extensive domestic and int’l R&E peering • Cost recovery model motivates network utilization and bandwidth upgrade 5 Abilene Community • 39 direct connections (OC-3c 10 Gbps) • 3 10 Gbps (10 GE) connections • OC-192c SONET also supported • 7 OC-48c connections & 3 GE connectors • 25 connected at OC-12c (622 Mbps) or higher • 234 Primary Participants – research universities and labs • Library of Congress and U.S. Holocaust Museum most recent additions • Expanded Access • 126 Sponsored Participants - Individual institutions, K-12 schools, museums, libraries, research institutes • 34 Sponsored Educational Group Participants - statebased education networks See: http://abilene.internet2.edu/ 6 The Abilene Network 7 The Abilene Network 8 The Abilene Network 9 The Abilene Network 10 The Abilene Network 11 Abilene Federal & Research Peerings 12 Abilene International Network Peerings 13 Advanced Services Across Abilene Advanced Network Services • IPv6 • Approx. ⅔ connectors, ½ peers are v6 enabled • 2005: 11 new non-production v6 peerings at Palo Alto PAIX, also added France Telecom, soon MCI MAE-West • MPLS • NC-ITEC experimenting (with ITEC Ohio) with creating a multipoint Layer 2 VPN using inter-domain MPLS tunnels & Virtual Private LAN Service (VPLS). • BRUW: experimenting with how to bandwidth reservation across packet and circuit switched networks • Abilene Observatory • Provides data from router nodes or equip. collocated in Abilene racks • 30+ research projects currently using Observatory data (see http://abilene.internet2.edu/observatory/research-projects.html) • Manhattan Landing (MAN LAN) @ 32 A of A in NYC - partnership with NYSERNet, Indiana University, and the IEEAF • A high performance, open bilateral exchange facility for research 15 Abilene Network Futures What’s Changed? • Over the last 5 years, the U.S. research university community has become wholesale customers of telecoms for raw assets & ancillary services • Upwards of 30,000 route-miles of inter-city dark fiber are held by the U.S. R&E community • > 60% in the regionals • More than 20 Regional Optical Networks (RONs) have emerged • mostly state based – some with strong gubernatorial support • often concurrent economic development objectives • Meanwhile carriers generally did not invest in new optical infrastructure during the downturn • Increased end-to-end network transparency • View of the network as a schedulable resource 17 Next Generation Abilene • Active examination of new network service models is underway • Group A Report - moving beyond the common bearer service view of best-effort IP • ‘Core’ and ‘Flexible’ waves • Hybrid architecture evaluation (HOPI Project) • IP core using 10→40Gbps λ transport • Dedicated capabilities using NLR wave and Abilene • λ’s, GigE channels, MPLS tunnels • Evaluation of optical transport capabilities • Both commercial and higher ed owned options (NLR & the RONs) • Design & planning collaboration with U.S. & international partners • ESnet, TeraGrid, NLR, SURFnet, GEANT2 18 Next Generation Abilene Timeline • October 2007 – End of recent 1-year extension to Abilene transport MoU with Qwest • Dictates 3rd-generation network timeline • • • • • Architecture: end 4Q05 Transport provider(s): end 1Q06 Equipment selection: end 2Q06 Backbone deployed: end 4Q06 Connector transition: begin early 2007 • Concurrently, need to review business and management models • Coincidentally… • Late 2007 – expiration of ESnet transport agreement with Qwest 19 NLR & Abilene • Group B Report recommended a merger of Internet2 and NLR as the best way to deliver to the community the services outlined in the ‘Group A’ report • Both Boards passed resolutions to begin consolidation discussions • Committee of 8 individuals has been appointed to develop a merger strategy plan • Work to begin immediately • Goal is to have a plan ready for each board’s consideration by the end of Oct. 20 Abilene / NLR Map 21 Next Generation Abilene Design Considerations Critical factors: • Complexity of delivering dynamic network bandwidth • NLR, RON and international integration • How do we deliver these services from the campus of one researcher to the campus of another • Advanced service support • Multicast, v6, High Performance Throughput, Measurement • Enhanced network research facilitation • Network and end-user security • Options for increased reliability and additional services (i.e. Commodity Internet services) 22 Abilene Information • For more Information: • • • • http://abilene.internet2.edu http://abilene.internet2.edu/observatory/ http://www.nationallambdarail.org http://hopi.internet2.edu • Or contact us at: • [email protected] • [email protected] • [email protected] • RONs / Abilene Connectors BoF • 8:15pm in Crystal Ballroom 3, Hilton Vancouver Metrotown 23 24
