Finished up talks for ESCC meeting at FNAL.
Les attended the ESCC meeting at FNAL and presented two talks on the IEPM
Warren & Les put together a presentation for the Surveyor group on PingER and
comparing the PingER and Surveyor results.
Prior to attending the ESCC meeting, Les attended the Surveyor Site
Contacts meeting at the IBM Global Services Center at Schaumberg Chicago and
presented the talk on
While at FNAL Les met with Bill Lidinsky, Eric He and Gary Roediger to go
over future activities for PingER and to coordinate activities between SLAC
and FNAL especially in light of Dave Martin leaving HEPNRC. Les wrote up rough
notes of the meeting in order to get a common understanding and sent it to
the attendees and Warren. Following a comment period, Les updated the notes to
to incorporate new information and sent them out for comment. Les also talked
Tony Johnson about some of the ideas.
We worked with the XIWT people to oragnize a
presentation for the upcoming XIWT/IPERF meeting in Washington in November.
reviewed XIWT SPSS proposal and made some suggestions. Unfortunately due to
prior engagements neither Warren nor Les can attend the meeting so the presentation
will be made by voice conference with Powerpoint transparencies transmitted in
advance by email.
A paper has been written and submitted for the proceedings to CHEP98.
The paper is based on the poster presented and a brief talk given at the
conference. The paper, talk and poster are all posted on the
The paper has also been released as a
Reviewed and commented on a
long memo from NetPredict on how to predict the average performance
for short time intervals given measurements over longer time intervals.
Later met with Netpredict to go over results and provide detailed feedback.
Business Communications Review (BCR)
The BCR paper is now available
An abstract has been submitted for
which will be held in San Jose. Abstract number 99026.
Les attended an Internet 2 meeting at Stanford at which (among other things)
Guy Almes presented information on the I2 architecture and Surveyor monitoring.
Warren made some changes to the summary area on the
that displays the monitoring results. It now has
the 25th, 75th, and 90th percentile values and the min/avg/max values.
Retrieved Data and made Reports for May and June. Also several Bug Fixes.
Added number of unique sites monitored.
Future of PingER
Warren has documented the projects
and plans for the future of the WAN
Monitoring work, at least as far as we see it.
Warren is porting pingtable to a Java Servlet.

Warren obtained some data from the Surveyor Monitoring effort, for
the paths slac->cmu and cmu->slac for September. The probe sends a packet
one-way approximately twice a second, so there is a huge amount
(40MB/month/pair) of data.
Warren converted it to our format and analysed it with our WAN-MON analysis
code. Warren wrote a new program to graph
the data along with the PingER data.
for Surveyor to the the
Warren also obtained data from the XIWT Monitoring effort. They are using the
SLAC code at eight Monitoring sites and archiving the data in a SAS database
at NIST. Warren copied the SAS files from NIST to FERMILAB and dumped
the SAS data to text.
