  14. US Federal Government: Next Generation Internet (NGI) Programhttp://www.ngi.gov • Established in parallel with Internet2 • Multi-agency research and development (R&D) program to develop, test, and demonstrate advanced networking technologies and applications • via testbeds that are 100 to 1,000 times faster end-to-end than today's Internet SBRC99 Salvador, Bahia, Brazil

  15. ESnet as example NGI net SBRC99 Salvador, Bahia, Brazil

  16. Internet2 <--> NGI Relationship • Similar technical objectives • Focused on different, but complementary communities • NGI: Federal Mission agencies • UCAID/Internet2: university research and education community • Working to interconnect, make interoperable federal research networks and Abilene SBRC99 Salvador, Bahia, Brazil

  17. Internet2 <--> NGI Relationship cont’d • Cooperative programs: • NSF High Performance Connections grants: UCAID universities using to connect to achieve Internet2 connectivity • Abilene <-> Energy & NASA network interconnections: provides high performance access for universities to research labs (One NASA network still to be peered with) • Applications: researchers benefit from numerous federal grants that help develop applications SBRC99 Salvador, Bahia, Brazil

  18. Internet2 International Activities • Why? • Ensure global interoperability of new technologies and applications • Enable collaboration between US researchers/faculty/students and colleagues outside US. using advanced networking capabilities SBRC99 Salvador, Bahia, Brazil

  19. International • How? • Form mutually beneficial relationships with organizations outside the US with: • Similar projects goals to Internet2 • Similar constituencies (institutions of higher education/research) • Establish interconnectivity • International networks come to US to peer • Establish collaborations in technology, applications development activities SBRC99 Salvador, Bahia, Brazil
