  1. Networking Grand Challenges NSF Future Directions Workshop April 2003

  2. Our panelists: • Ravi Mazumdar, Purdue • Larry Peterson, Princeton • Lixia Zhang, UCLA • Jean Walrand, Berkeley Moderator: Don Towsley, UMass

  3. Is networking in doldrums? • stagnant economy • uncertain funding picture • world affairs • SARS • university budget cuts 

  4. layered networks wireless Internet mobile interplanetary sensornet high performance 10 years  These are exciting times!

  5. Charter of panel • what constitutes a grand challenge? • intra area? e.g., one petabyte transfer in < one second • inter-area? how to design robust networks independent of technology/application • what are some of the grand challenges?

  6. What are the important research challenges? • timeless(still unsolved) problems? how to build robust networks that scale with technology to handle diverse apps (1965) • what are the new drivers: • technological? • applications? • social? • short-term versus long term challenges?

  7. Observation: diversification of community • 1994 - INFOCOM, SIGCOMM portions of Globecom, ICC • 2003 - INFOCOM, SIGCOMM, ICNP, IMC, MOBICOM, MOBIHOC, MOBISYS, WCNC, web/P2P/CDN conferences, … portions of many other conferences Are we splintering?

  8. Observation: diversification of community • 1994 - INFOCOM, SIGCOMM portions of Globecom, ICC • 2003 - INFOCOM, SIGCOMM, ICNP, IMC, MOBICOM, MOBIHOC, MOBISYS, WCNC, web/P2P/CDN conferences, … portions of many other conferences Challenge: how to maintain communication / interactions? NSF role?

  9. Panel Format: • panelists (short) presentations (8 min each) • panelist observations/questions • open discussion Ravi Mazumdar Larry Peterson Lixia Zhang Jean Walrand Don Towsley

  10. A network science? Goal: to answer questions like • why do topologies look as they do? • why do disruptive apps appear? what are their effects? • a single bottleneck link? multiple botteleneck links? on end2end paths Components: • physical laws, mathematics, algorithms, markets • components change over time (how?) • parallel networks (universes)

  11. A network science? • multidisciplinary – stat/probability, computer science, nonlinear systems, market economics, communication theory, complex systems, … • experimental methods, need for data • translation into engineering As challenging/important as physics, biology, …

  12. Evolution of the Internet

  13. What have we heard? • mathematical theories to: • understand performance limits • compute/communication/sensing tradeoffs with power constraints • understand as a complex system • how to design evolvable networks • how to design resilient (tolerate any fault) networks • how to design markets and network mechanisms to support future heterogeneous apps
