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

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)

e2e• Van Jacobson's congestion control (slow start and

all that...)• IP Multicast• TCP large sequence numbers and window scale

(PAWS)• TCP SACK• Explicit Congestion Control• VIC & VAT• Quality of Service: Diff Serv and Int Serv• RSVP• Standardizing SUN RPC for the Internet• T/TCP

Cisco areas of interest

• Wireless and mobility• Innovating the World Wide Web• Adaptive overlay architectures for time-sensitive

traffic delivery • Packet classification and protocol description

languages• Innovating the optical layer• Innovation on power• Unsolicited proposals are welcome also• <http://www.cisco.com/research>
