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

• 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.

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
