  1. ORNL Net100 status March 26, 2002

  2. ORNL Net100 • Focus Areas (first year) • TCP optimizations (WAD, AIMD, VMSS, ns, atou) • Network tool evaluation (iperf, webd, java/web100) • Bulk transfer optimization (NERSC/ORNL) • Today’s agenda • Activities since Denver meeting • Current activities / WAD status • Future work/needs • Nagi’s update

  3. ORNL activities since Denver meeting • Web100 tuning (manual) of HSI transfer (NERSC/ORNL), SC2001 • NISTNet testbed • SCTP study/report • autotuning WAD (version 0) • TCP tuning (AIMD, VMSS) with ns and atou • Web100 event notification • Evaluation of Linux 2.4 tuning • DRS testing (ESnet, NISTNet), integration with Web100 (2.4.16) • TCP Vegas testing/porting (ns, Linux, atou) • atou tech report • Outreach: Net100 talks, web pages

  4. AIMD and Virtual MSS experiments experiments with atou between NERSC and ORNL

  5. WAD • Version 0 • tune unknowing sender/receiver • static config file with “tuning info” • tuned parallel iperf flows • To be done (year 1) • V1: use netlogger data to get tuning data (like Enable) at start of flow • add AIMD/VMSS tuning to kernel and tuning info to config file • systematic tests • V2: tune during flow, using web100 polling and data from remote WAD

  6. Rest of year ... • WAD enhancement and testing • integration of metrics with tuning • webd integration ? • SC2002 paper prep • gridftp tuning (or other bulk transfer demo ??) • TCP optimization studies (AIMD, Vegas, ?) • AIX web100 port ? • ESnet jumbo frame and ECN tests ? • ESnet router data ? • Addition of postdoc • Outreach: ESnet ESCC meeting (April), Internet2 (Jul/Aug), SC2002
