Internet a rich source of problems
• Technical– Routing failures– Congestive collapse– Fast long-distance networks– Insecurity

Internet a rich source of problems
• Technical– Routing failures– Congestive collapse– Fast long-distance networks– Insecurity
• And social– “Green card” spam– RBN, etc.

Gigabit testbeds (1990-1995)
• How Slow is One Gigabit per Second? - Craig Partridge, 1990
• Cooperative agreement with CNRI (Bob Kahn & Dave Farber)
• NSF & ARPA funding: $20m USD over 5 years• Industry contribution “10-20 times as much”• Five testbeds• OC-48 trunks, SONET

Charles Herzfeld, former Director ARPA, former DDR&E:
When President Eisenhower said, ”You, Department
X, will do Y," they'd salute and say, ”Yes, sir." Now
they say, ”We'll get back to you." … agency heads
are all wishy-washy.
What's missing is leadership that understands what it
is doing.

FIND and GENI
• GENI cost estimate is “at least” $367m– Larger in scope than Gigabit testbed project…– …but similarly organized– GENI project office– GENI Science Council
• FIND funding $30-40m/year for 5 years– > 40 currently funded projects– Some cited by name in GENI program documents– “There are many ideas that are good and new…”

IRTF• The Chairs of six of the fourteen Research Groups
comprising IRTF have funded FIND proposals -– dtnrg– eme– end2end– imrg– p2prg– rrg
• cfrg “seeded” GCM mode for IPSec (RFC 4106) and UMAC message authentication (RFC 4418)
