1 Web100 at SLAC Presented at the Web100 Workshop, Boulder, CO, August 2002.

2 OverviewOverview Review Web100 at SLAC Applications Results IEPM-BW MAGGIE

3 The Needs of HENP BOF in Nebraska. SLAC is a data center. Transfer multiple TeraBytes to France, UK. Need to optimally configure ftp-like applications to maximize throughput. Track loss, RTT, throughput. Modify streams and window size.

4 ExpectationsExpectations Take out the guess work Maintain optimal parameters Improve throughput

5 Web100 at SLAC Initial test and development machines. Two main production machines –Antonia, Hercules Other testbed machines are web100-enabled by default. Utilize Net100 extensions and turn off 2.4 caching.

6 ApplicationApplication webdump (tcpdump-like) program Iperf –Short transfers dominated by slow start –Modify iperf to use web100 to identify when slow start has finished and report throughput

9 ResultsResults iperf vs web100 vs passive (netflow) Stream by stream for a whole transfer –Not progressive

10

11 IssuesIssues Dynamically select CID What is interesting ? Real-time Streams and Windows prediction

12 IEPM-BWIEPM-BW Continuously operating high performance throughput measurement project. Poor mans AIME (not funded by SciDAC). Iperf, bbcp, bbftp, udpmon … Track, compare, contrast 3 Monitoring Sites (SLAC, FNAL, UMan) –I2, UMich, NIKHEF, APAN/JP 33 Active Participants (US, Europe, Japan)

13 IEPM-BW and WEB100 Option to dump subset of stats to a file –Not default

14 MAGGIEMAGGIE Measurement and Analysis for the Global Grid and Internet End-to-end Performance. Big sister of Active Internet Monitoring for ESnet (AIME). 10-20+ NIMI hosts running periodic and on-demand measurements. Feedback results to instrument tools and troubleshoot issues.

15 MAGGIE+MAGGIE+ Atlas Internet2 –Performance Analysis Stations –I2 E2E PI PE PPDG Work with these and others to create co- operative framework Continue IEPM-BW work.
