  1. IEPM. Warren Matthews (SLAC) Presented at the ESCC Meeting Miami, FL, February 2003.

  2. Overview • Internet End-to-end Performance Monitoring (IEPM) • PingER • IEPM-BW • MAGGIE • Web Site • http://www-iepm.slac.stanford.edu http://www-iepm.slac.stanford.edu

  3. PingER • Ping End-to-end Reporting • 10x100 Byte pkts, 10x1000 Byte pkts • Started in 1995 • Currently 36 monitoring sites in 14 countries • Long term trends and short term glitches • Continues to prove useful • Project with ICTP/eJDS on Digital Divide

  4. Transatlantic link was 2Mbps in 1995. Now Multiple OC12. Vacation Traffic on ESnet doubles every year

  5. IEPM-BW • Direct Monitoring • Currently 10 monitoring sites • North America, Europe and Asia • 1-6 target sites each (40 at SLAC) • Iperf, bbftp, bbcp, gridftp, udpmon … • Network and applications

  6.

  7. Network Host

  8. Available B/width Estimator • Tests impact the network • Can cause problems for “real” traffic • Can trip over each other • Prefer low-impact tools • Can also be run more often • ABwE • INCITE (SLAC/RICE/NLANR) • Results comparable to high impact tools

  9. Sat Sun Mon Tues Weds Thurs

  10. MAGGIE • Measurement and Analysis for the Global Grid and Internet End-to-end Performance • A secure, scalable measurement infrastructure providing measurement, analysis and access to data.

  11. Features • IEPM-BW + SCIDAC + Other tools • Security • Akenti/Shibboleth • Access to Data • MDS, Web Services • Troubleshooting tools survey other sources • Deploy in DoE Science Community • Work closely with PIPES (Internet2)

  12. The Need • A need for a ubiquitous monitoring infrastructure ? • DOE Science Community • SCIDAC testbed • Large Scale Networking • Grid (especially resource brokers) • Troubleshooting / E2Epi

  13. Toward a Monitoring Infrastructure • The pieces are coming together • Many monitoring projects • Internet2 NG with built-in monitoring • E2e PIPES • Join in !

  14. End • SLAC team led by Les Cottrell • Warren Matthews • Connie Logg • Jiri Navratil • Jerrod Williams • Fabrizio Coccelletti (INFN) • Frank Nagy, Maxim Grigoriev (FNAL) • And all the local administrators/supporters. • Funding by DoE MICS / SCIDAC
