vBNS national network program
• support national and global scale R&E
– leading edge but stable technology
– always beyond the commercial Internet
• model network technology of the future
– RSVP, QoS, IPV6
– tech transfer to commercial Internet
• enable new applications in R&E
Connections to the Internet
• vBNS companion grant program announced
in March, 1996
• support networking for meritorious science
that cannot be accomplished on the
commodity Internet
• promote designs that share resources with
QoS and can scale to R&E (+ Internet)
Program requirements
• $350,000 one-time grant to a campus
– offered every January 31 and July 31
– 64 awards so far; 63 more just proposed
• institutional match and continuation
– costs and availability vary dramatically
– some start at DS3 and move to OC3 later
• require collaborative planning for
connections in lab, campus, region, etc.
Connections awards to date
• 1995:
5 supercomputing centers
• May 96: 14 university sites
– interconnect with NASA and DOE
• July 96: 14 university sites
• Jan 97: 35 university sites
– interconnect CA*Net 2 and IDREN
• July 97: 60+ proposed new connections
– interconnect with more countries at STAR TAP
NSF vBNS partners to date
• Argonne National Lab (ANL)
• Fermi National Accelerator Lab (FNAL)
• Interim Defense Research and Engineering
Network (iDREN)
• Energy Sciences Network (ESnet)
• NASA Internet (NREN)
• Canadian Research Network (CA*net II)
• Defense Research and Engineering

vBNS midterm review
• expert panel review in August, 1997
• review history, changing environment
– MCI technical performance “excellent”
– now PACI, NGI, globalization, Internet2
• strongly endorse expansion to 100+ sites
– NSF strategy
– need for continued NSF involvement

HPIIS: High Performance
International Internet Services
• promotes links between the vBNS and highperformance research networks of other countries
• connections at STAR TAP encouraged
• for “high-end” institutions on foreign nets
• widely anticipated among international highperformance networking community
• $ 4.5 million budgeted annually for up to 5 years
• awards later this year
NGI: Next Generation Internet
• federal program to unify and focus federal
activities in advanced networking
–
–
–
–
proposed $100 million per year for 3 years
government, university, industry partnership
coordinate network R&D across agencies
coordinate federal research networks
• implementation planning team in LSN
• joint engineering team
vBNS role in NGI
• national-scale platform for new technologies
• central role in “connect 100+ institutions...”
– core network of both Internet 2 and PACI
– interconnect with U.S. research networks
– interconnect with foreign research networks
• cooperate in “connect 10+ institutions”
• national platform for new applications
vBNS role in I2
• vBNS selected initial backbone network
– members develop campus nets and gigaPops
– apply to NSF for connections to vBNS
• partner relationship for
– engineering and operations
– new technologies
– applications
• a running head start
NLANR: National Laboratory
for Applied Network Research
• distributed staff
• expert support for advanced networking
– engineering, user services, research
– performance, statistics, measurements,
multicast, caching, applications, collaboration
• scale up to help vBNS expansion
– workshops, documents, web site
– “Good neighbor policies”
