Work Related to Analysis and Development

PingER

Warren worked with the local administrator at DESY to resolve a prolem with their connectivity.pl table.

Warren worked with the local administrators to revive data taking at LANL, BNL, and WISC. There was an interruption in data taking at JLAB. The problem has been resolved. There is a new PingER site at the Pacific North West GigaPOP (PNG).

IEPM-BW

Warren worked on setting up the target sites monitoring from Georgia Tech. Warren worked with the administrators to set up targets at Florida State University (FSU), and University of Alabama at Birmingham (UAB).

Warren worked with Jerrod to fix problems processing the data.\

Les evaluated an improved bwtests time series graph from FNAL.

ABwE

Warren installed Jiri's 'Available Bandwidth Estimater (ABwE) at Georgia Tech and the target sites.

OWAMP

Warren worked with Eric Boyd to access the one-way latency measurements.

High Performance Measurements

Les worked on a problem with hung processes on testbed hosts at Sunnyvale. He is also working on logistics for the 10GE tests to be made from Sunnyvale, still awaiting the Cisco 10GE cards. LANL is ready to deliver the 10GE PC interfaces. He also set up monitoring from RAID file server host at SNV to Chicago and CERN and SNV.

Setting up to make measurements from Sunnyvale to NIKHEF. Got disk space and host at SURFnet POP at SARA (next door to NIKHEF). Ran into problems with routing. Working with StarLight to resolve.

At SC2002 the NIKHEF/SLAC/Caltech team broke the Internet 2 Land Speed Record (LSR). Les discussed with NIKHEF, Caltech and Internet 2 folks on our Internet 2 Land Speed Record submission from SC2002.

Made testbed measurements with jumbo frames, also measurements with iperf and file transfers using the FAST and standard TCP stacks (see http://www-iepm.slac.stanford.edu/monitoring/bulk/fast/).

NIMI

Fabrizio Coccetti brought back the NIMI monitoring host at SLAC.

Web100

Jerrod fixed a problem with installing web100 on SLAC AFS systems.

eJDS

Warren and Les added more sites to the new ICTP/eJDS monitoring project. There are now 18 nodes in the ICTP group.

Warren made contact with the administrators in Iran and Nigeria to learn more about networking in those countries.

Globus

Warren brought up MDS with the EDG extensions, and added some PingER monitoring data.

Warren and Les attended a GLUE conference call about Network Elements

Warren worked with someone from KEK to run GridFTP tests.

PIPES

Warren talked with Yee-Ting Li about communication between the PIPES measurement devices (PMP).

Tsunami

Warren talked with Yee Ting Li about running some Tsunami tests.

Visit

Warren arranged for Eric Boyd and Russ Hobby from the Internet2 http://www-iepm.slac.stanford.edu/about/status/e2epi/mins-jan03.html
