Gigabit testbeds ( ) 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

Gigabit testbeds (cont’d)

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)
