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
