  1. Reflections on Internet research stephen wolff cisco research center (not an alias for cisco m & a)

  2. IETF02 - April 1986

  3. Networking textbooks Kleinrock Stallings Tanenbaum Bertsekas & Gallagher … and only one of these

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

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

  6. 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

  7. Gigabit testbeds (cont’d)

  8. 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.

  9. 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…”

  10. 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)

  11. 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

  12. 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>

  13. Thank you
