  1. What's happening in Networking Research Today?Prasad Calyam, OARnetOARTech Presentation, Dec 8th, 2004

  2. Overview • Introduction • What are the networking research topics being discussed these days? • Networking Research at OARnet! • In which conferences are topics on networking research being discussed? • Conclusion

  3. What are the networking research topics being discussed these days? Traditional Network QoS research (E.g. Diffserv, Intserv) has become very quiet! • High-performance TCP • To support bulk file transfers and resource sharing amongst the Grid Communities (e.g. HENP, VLBI communities) • Fast TCP, XCP, Non-friendly TCP with minimum rate control (DSTP) • Buffer size issues, MTU issues • Internet Geometry/Architecture • Topology, Tomography, Routing Design • Network Performance Measurement and Characterization • Bandwidth estimation tools, Routing stability, MPLS, Congestion management, Network Troubleshooting techniques, Next-generation Measurement Infrastructures

  4. What are the networking research topics being discussed these days? (2) • Wireless Networking • WLANs, Cellular Networks, Sensor Networks, Adhoc Networks • Network Security • DDoS traceback and defense mechanisms, Access Authentication and Authorization (AAA) middleware • Many others… • Optical Networks, Overlay Networks, Peer-to-Peer Networks, Multimedia Gaming Networks, Multicast Networks, Satellite Networks

  5. OARnet Networking Research • “H.323 Beacon” (Open source – runs on Windows and Linux) • A tool to measure, monitor and thus troubleshoot the performance of an H.323 Videoconference sessions • Official troubleshooting tool for Internet2 Commons and Megaconferences- The world’s largest Internet Conferences • Presented at ACM Network Troubleshooting Workshop, Sepember 2004 • Modeling Voice and Video Traffic over IP • We setup a worldwide testbed involving 26 sites and collected over 300 traffic traces • Our results demonstrate the impact of various audio and video end-point codecs, packet size distributions, network jitter, lost and re-ordered packets on the end-user perception of audiovisual quality • Presented at Passive and Active Measurement Workshop, April 2004

  6. OARnet Networking Research (2) • “ActiveMon” (Open source – runs on Windows and Linux) • A scalable Network Measurement Framework for setting up active measurements along multiple network paths • Developed as part of the BORTFN MeasurementProject • Understanding Internet Backbone Network Characteristics • Studying empirical bottlenecks – cause and resulting performance issues • Using ActiveMon to study Internet Traffic patterns on Campus-level, Regional-level and National-level network backbone paths • To be presented at IEEE Testbeds and Research Infrastructures for the DEvelopment of NeTworks and COMmunities (TRIDENTCOM), February 2004

  7. In which conferences are topics on networking research being discussed? • 3 sets of communities that address Networking Research • Network Engineering Research Community • Care more about practice • Focus on short-term issues • E.g. I want to setup IPv6 with XYZ specifications. What sequence of tasks work most effectively? • Work mostly on real-world systems • Network Development Research Community • Care about both theory and practice • Focus on reasonably long-term issues • E.g. How do I extend TCP with the novel CDE technique so that it will improve the performance of RST type of network flows in the Internet? • Work on simulators and real-world systems • Theoretical Research Community • Care more about theory • Focus on very long-term issues • E.g. If I use PQR technique to detect DDoS attacks which involves changing A-Z of today, will the network fairness improve? • Work mostly on network simulators

  8. In which conferences are topics on networking research being discussed?(2) • Refereed • Focus on high-impact Issues • SIGCOMM, HOTNETS, SIGMETRICS, … • Focus on wide-range of Issues • INFOCOM, GLOBECOM, ICC, ICN, Networking, ICDCS • Focus on area-specific Issues • Mobicom, PAM, IMC, NOSSDAV, SECON, NetTs, TRIDENTCOM, Global IPv6 Forum… • Non-Refereed • NANOG, Internet2/ESCC Joint Techs •  Webinars • E.g. www.lightreading.com
