ICFA/SCIC Monitoring WG

1. ICFA/SCIC Monitoring WG Les Cottrell – SLAC representing the ICFA/SCIC Monitoring WG Prepared for the ICFA-SCIC, phone meeting, Jan 15, 2003 http://www.slac.stanford.edu/grp/scs/net/talk/icfa-jan03.html Partially funded by DOE/MICS Field Work Proposal on Internet End-to-end Performance Monitoring (IEPM), also supported by IUPAP

2. Updates to report since Dec-02 1/2 • N. America => Anglo America (thanks Sergio) • Paragraph on improving TCP (under IEPM-BW) • Paragraph in the Summary on the collaboration with ICTP • Recommendation to actively encourage/extend the ICTP collaboration with some specific goals • CHEP03 paper, poster, web site, • Contact with NGOs • UNESCO, UN, Soros Foundation • Contact with EU

3. Updates to report since Dec-02 2/2 • Updates: 650=>791 hosts, 444=>482 sites,74=>79 countries • Added 23 new sites from ICTP collaboration • 17 countries: BD, BR, CN, CO, GH, GU, IN, ID, IR, JO, KR, MX, MD, NG, PK, SK, UA)

4. Not done from last time • “We need a part of the monitoring report that relates to the needs of major HENP experiments, for example the needs of Tier 1 sites for data replication, in addition to the lighter weight needs for collaboration  from smaller groups and individuals sites with poor connectivity. We could/should include the needs of a major experiment such as BaBar as a function of time driven by tier A centers as a natural feature of W. European countries and the US. Richard Mount agreed to add text relating the monitoring results to HENP requirements as a function of time. [Note: Charles Young of SLAC also agree to work on Requirements in ICFA SCIC, so Richard should contact Charlie as well.] “

5. Possible Improvements • Unclutter figs 2, 6, 8 by only showing trendlines • Could: • Show ~ max throughput measureable by PingER for ESnet & Abilene (depends on RTT so no single number) • Show minimum RTT for ESnet sites assuming distance/(0.6*c) {or should it be distance/(0.3*0.6*c)} • Table 2 & Fig 7 are too wide for paper • I will be unable to make anything but trivial modifications until 2nd week in February

6. Countries in PingER DataBase* Albania Argentina Armenia Australia Austria Azerbaijan Bangladesh Belarus Belgium Brazil Bulgaria Canada China Chile Colombia Costa Rica Croatia Cuba CZ DK Egypt Estonia Finland France Georgia Germany Ghana Greece Guatemala Hungary Iceland India Indonesia Ireland Iran Israel Italy Japan Jordan Kazakhstan Korea, Republic Of Latvia Lithuania Macedonia Malaysia Mexico Moldova, Republic Of Mongolia Netherlands Nigeria Norway New Zealand Pakistan Peru Poland Portugal Puerto Rico Romania Russia Singapore Slovakia Slovenia South Africa Spain Sweden Switzerland Taiwan Thailand Turkey Uganda United Kingdom Ukraine US Uruguay Uzbekistan Venezuela Viet Nam Yugoslavia * Means we monitored a host in this country at one time or another
