  1. U.S. Government sponsoredNext Generation Internet Program--NGI--

  2. President Clinton - October 1996 • “Connect universities and national labs with high-speed networks that are 100 - 1000 times faster than today's Internet. These networks will connect at least 100 universities and national labs at speeds that are 100 times faster than today's Internet, and a smaller number of institutions at speeds that are 1,000 times faster. These networks will eventually be able to transmit the contents of the entire Encyclopedia Britannica in under a second.”

  3. NGI Agencies • DARPA • NSF • DoE • NASA • NIST • NLM

  4. Goal 1: Research • Coordinated, multi-agency development, deployment, and demonstration of the technologies necessary to permit the effective, robust, and secure management, provisioning, and end-to-end delivery of differentiated service classes • These activities cluster into three major tasks: • Network Growth Engineering • End-to-End Quality of Service (QoS) • Security

  5. Goal 2: Network Testbeds • Create and deploy tools and algorithms for planning and operations that guarantee predictable end-to-end performance at scales and complexities of 100 to 1000 times those of the current Internet • Facilitate management of large scale inter-networks operating at gigabit to terabit speeds supporting a range of traffic classes on a shared infrastructure • Create a network testbed of at least 100 institutions through which users (government and research) share facilities, thereby accelerating the development and penetration of novel network applications

  6. Goal 3: Applications • Applications should need NGI speed or services, i.e., be something that could not be done before NGI • Applications should have high visibility

  7. NGI Services Needed by Applications • Strong Security • Adaptable Net Management • Selectable Loss Rate • Scaleability • Multicasting • High bandwidth • Bandwidth reservation • Low latency • Low jitter • Nomadicity • Real-time • Variable priority

  8. Health Care Environment Education General Science Crisis Response Manufacturing Federal Information Services Collaboration Distributed Computing Security & Privacy Digital Libraries Remote Operations Sample Application Areas

  10. NGI FY-1998 Funding by Goal

  11. A Partnership

  12. NGI and Internet 2: Complementary and Interdependent

  13. NGI and Internet 2: Complementary and Interdependent

  14. Engineering Objectives • Deploy a production network to support applications R&D • Establish quality of service (QoS) • Support native multicast • Establish gigaPoPs as effective service points

  15. ESnet (DREN) JETnets

  16. Joint Engineering Team (JET) • A forum of NGI, Internet2 and other federal networks/agencies mainly for technical exchange and coordination • Focused on interconnection and peering of JETnets in support of end-to-end services • Facilitates joint (inter-agency, states, I2) efforts for special connections like Alaska and Hawaii • Joint meetings with Gigapop operators

  17. JETnets NGI Funding and Service Types NSF funds vBNS (directly and indirectly) and Abilene (indirectly)

  18. Advanced Services • IP multicast: all JETnets (except NISN) have native multicast running in production mode using the PIM-SM, MBGP and MSDP protocols -- 1999 is the year native multicast became real in the backbones (still not on many campuses) • IP QoS: Abilene, ESnet, NREN and vBNS are active members of the QBone project (inter-domain diffserv); vBNS has offered “reserved b/w” service using RSVP/ATM • IPv6: all JETnets are part of the 6Bone project and vBNS is testing a native IPv6 service (separate routers)

  19. Performance Expectation and Issues • For OC3 or higher connected sites with 100Mbps switched campus nets and fine tuned end systems (and no firewall in the path) you can expect 80 Mbps end-to-end (memory to memory) - this is not the TYPICAL case • Most performance bottlenecks are in the end systems: lack of path MTU discovery, TCP implementation, multiple memory copying and buffer management; there are also problems in local networks (under-power routers) • NGI program first phase mostly focused on wide area nets, now we are focusing on local nets and end systems

  20. Interconnect Issues NGIX effort: NGI / Internet2 JET Chicago: OC-3 going to OC-12 Ames: OC-12 Washington: OC-12 as soon as possible International: StarTap plus Emphasize StarTap as the universal solution Optimize where appropriate Canada as an important special case

  21. NLM’s Extramural NGI Applications Program • May 1998 - February 2000 • NRC / CSTB study • September 1998 - June 1999 • Phase I Awards: Planning • September 1999 - June 2002 • Phase II Awards: Implementation • October 2002 - September 2005 • Phase III Awards: Scaling

  23. Phase I: Planning (FY-99) • 9 month planning phase • Awards not to exceed $100,000 • 24 awards made to 18 universities and 6 companies

  24. Phase I: Planning (FY-99) Lessons Learned • Some healthcare applications require high bandwidth, but many do not • Most healthcare applications require Quality of Service (QoS) guarantees • Most healthcare applications can run more economically over the Internet if QoS can be guaranteed

  25. Phase I: Lessons Learned (FY-99) Need for NGI in Radiology • Digital radiology of the chest • Mammography • MRI study • Echo-cardiogram study • 200 mbits • 1,600 mbits • 2,000 mbits • 40,000 mbits Utilization of a 155 mbit line • 10%

  26. Phase I: Planning (FY-99) Lessons Learned • The need for a medical data privacy and intellectual property policy is the major inhibitor of healthcare use of a Next Generation Internet
