ICFA/SCIC Monitoring WG

Les Cottrell – SLAC representing the ICFA/SCIC Monitoring WG

Prepared for the ICFA-SCIC, phone meeting, Jan 15, 2003http://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

Updates to report since Dec-02 1/2

• 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

• N. America => Anglo America (thanks Sergio)

Updates to report since Dec-02 2/2

• 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)

• Updates: 650=>791 hosts, 444=>482 sites,74=>79 countries

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.] “

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
