  1. Thoughts on Networking Research Bob Kinicki PEDS Presentation October 6, 2003 Networking Research

  2. Major Internet Issues • Growth • Applications and Quality of Service • Open versus Security {in conflict!!} • Wireless • Mobile • Future Architectures Networking Research

  3. Growth • What will cause Internet growth? • How will wired and wireless integrate? • How much congestion will this produce within the Internet? • Where will the bottleneck be? • Can we predict the growth? • Requires measurement! Networking Research

  4. T X Z W1 W Y Host L Video W2 Host M Host K Host A W3 AP 2 3 4 1 5 Host B 16 W4 nodes 14 11 17 12 Host C 15 6 13 10 7 Host H 9 8 Host D Host G Web Server Host E Host F Peer –to-Peer Networking Research

  5. Congestion Control Research • Modifying TCP • Making non-TCP traffic TCP-Friendly • New congestion control algorithms at the router • ECN (Explicit Congestion Notification) • Jae Chung: new congestion control algorithm • Min Kim: TCP source hint for fairness to Web traffic • XCP, PI, AVQ,SFC, REM, … Networking Research

  6. Congestion Control Research • Will over-provisioning remain viable? • Will pricing force class-based traffic routing? Networking Research

  7. Quality of Service • Balance needs of different applications • Abhishek Kumar: delay versus throughput balancing • Aggregating flows at the ingress router Networking Research

  8. Applications • Streaming Media • Using FEC (Forward Error Correction) • Huahui: Using FEC with temporal and quality scaling • TFRC (TCP Friendly Rate Control) • Mingzhe’s current project • Using Partial Retransmissions • Yubing’: retransmissions related to RTTs • Measurement • Available Video - Mingzhe paper • Media Server - Jim Nichol’s masters Networking Research

  9. T X Z W1 W Y Host L Video W2 Host M Host K Host A W3 AP 2 3 4 1 5 Host B 16 W4 nodes 14 11 17 12 Host C 15 6 13 10 7 Host H 9 8 Host D Host G Web Server Host E Host F Peer –to-Peer Networking Research

  10. Applications • Web Traffic • Many possibilities here , e.g. Prof. Wills, Mikhail, and Hao • What is the future of flash crowds? • Peer to Peer Traffic • Impact ? • New research area for PEDS • Overlays to handle multicast • Overlays to combat denial of service attacks Networking Research

  11. Open Networks and Security Networks in Conflict • Acceptable security depends on context and circumstances • Where should the security be positioned? • Ingress versus egress? • Outside the perimeter  Not at the firewall! • Upstream within core routers • Wireless changes everything Networking Research

  12. Security Problems • DOS and DDOS (Distributed Denial of Service. • Wormholes • Flash crowds versus DDOS • Intrusion Detection schemes Networking Research

  13. T X Z W1 W Y Host L Video W2 Host M Host K Host A W3 AP 2 3 4 1 5 Host B 16 W4 nodes 14 11 17 12 Host C 15 6 13 10 7 Host H 9 8 Host D Host G Web Server Host E Host F Peer –to-Peer Networking Research

  14. Wireless • Hot Area!!! • Handling packet loss due to errors in communication • “Fu Fighter” research • Hidden terminal problems • Streaming over Wireless Networking Research

  15. Mobile • When wireless nodes move around they become routers • Need new MANETs with special algorithms that included router communicaitons • No students currently working here!! • Military need secure MANET technology  this will happen Networking Research

  16. Future Architectures • Mobile Wireless addressing issues • IPv6 • Other countries moving ahead here • Internet2 • WPI is part of Internet2 • Unheard of capacity Networking Research

  17. Final Remarks • Plenty of research opportunity for new PEDS students • Master Students need to begin to focus in fall so that you can pick a topic by the end of the first year • At least six choices from PEDS faculty for research advisor Networking Research
