Report on IEPM PPDG efforts for PPDG for the quarter July
- September 2004
Report prepared by Les Cottrell, October, 2004
Collaboration with IEPM, Network Performance Monitoring
Bandwidth/Throughput measurement (IEPM-BW)
We presented a talk on the Internet End-to-end Performance Monitoring at
the Energy Science Network Site Coordinators Committee (ESCC) meeting,
Following concerns about the impact of iperf testing on network
traffic, we examined the effects and documented them at
We added U Victoria to the sites monitored by IEPM-BW.
We installed and studied BWCTL from Internet 2 which we will use for
scheduling on-demand bandwidth measurements.
Lightweight Bandwidth Estimation
We assisted the people from SDSC/CAIDA to evaluate pathload on the
Bandwidth performance anomalous events
We implemented and extended the
We have tuned the anomalous event detection using the "Plateau
Algorithm" to minimize diurnal effects.
Traceroute Analysis and Visualization
We gave a talk on
Traceanal: a tool for analyzing and representing traceroutes
We improved the traceroute topology visualization tool and applied
it to the AMP data and incorporated it into the IEPM-BW traceroute
We worked with Florida International University to get agreement to
install a PingER monitoring site there. This will be particularly
useful to understand South American connectivity. We also successfully set
up monitoring to an Indian commercial site (most PingER sites are Academic &
Research, and we want to find out if the poor performance to India
extends to commercial sites.
We worked with NIIT/Pakistan to develop a mouse sensitive map of
SC2004 Bandwidth Challenge
We set up a collaboration with Caltech, FNAL, University of Manchester, England,
several companies (e.g. Chelsio, S2io, Sun), ESnet, National
Lambda Rail and other to participate in this
year's SC2004 Bandwidth Challenge. For more details see the web site at
As part of this we secured loans of two 10GE wavelengths (from NLR and
ESnet/QWest) from Sunnyvale to
Pittsburgh (this year's site for SC2004), the loan of eleven Sun Opteron
compute servers, 11 10GE interfaces, three Sun file servers, Cisco
equipment (XENPAKs and routing blades), space at the Sunnyvale
CENIC point of presence.
Proposals and Representation
We submitted and had accepted a proposal to the US Department of State
and the Pakistan Ministry of Science and Technology
for Measurement and Analysis for the Global Grid and Internet End-to-end
We amended the DoE/SciDAC proposal on
TeraPaths: A QoS Enabled Collaborative Data Sharing Infrastructure
for Peta-scale Computing Research, had it accepted and
received funding. A two page summary of the new proposal can eb found at
SLAC is a partner in the UltraLight optical testbed
proposal (led by Caltech) which was funded
by the NSF.
We collaborated with Texas A&M, NASA and others to submit a proposal
to NASA on developing and monitoring IP based protocols for NASA satellites etc.
We attended the NASA/LSN workshop on Optical Network Technologies
at NASA Ames. We prepared and gave a presentation on WAN Monitoring
also served on a panel.
Submitted paper with FNAL to CHEP04 on Wide Area Networking System for
HEP Experiments at FNAL.
We attended the DoE PI network research meeting at FNAL and made two
