Adib is waiting to hear from colleague (Dr. Nordin: chair of ISTT2014), there was no update as of this meeting. The conference is 2 days so the workshop may be squeezed to one day. The conference will be held in Langkawi between 24-26 Nov.
Hopefully, this will help us to attract good number of participants and get sponsor/support to cover our expenditure. Other option is to conduct the workshop in UUM, we are ready to provide Local Arrangement (lab, local transportation, and food). But there is no funding provided by the school to support the transportation/accommodation of the speakers.
- Anjum will try and contact Adib. Anjum is also putting together a conference on cloud computing in November. I Anjum may be possible to co-locate the PingEr workshop with this conference.
Adib or Johari shall be able to inform relating our discussion. Adib is trying a number of options and there is some progress.
Anjum talked to his supervisor. He is showing revived interest in Pinger. He was busy the day Anjum talked to him. Anjum will have another meeting with him on friday to further discuss the possibility of combining the conference with workshop.
Les will be in Burkina Faso Nov 13-21. He flies back to London on Nov 22nd. He can get to Malaysia mid morning November 24th. Les will be in Burkina Faso Nov 13-21. He flies back to London on Nov 22nd. He can get to Malaysia mid morning November 24th. Thus the workshop should be at the end of the ISTT2014 meeting if Les is to attend.
- Anjum suggested putting together a paper on metrics provided by PingER for Sigmetrix. The due date is in November.

To assist in SEECS gathering data: nodes.cf is now available via http://www-iepm.slac.stanford.edu/pinger/tools/. Also to assist in debugging some problems with gathering and checking the data the SLASC versions of checkdata.pl and checkdata_gif.pl are available at the same place.
Raja
.pl and checkdata_gif.pl are available at the same place.
Raja
Raja has improved Raja, Umar and Les have submitted the paper on TULIP and its application to Visual Tracerouting to the Vancouver conference in November. Aceptances are due in July. Raja is improving the GUI for TULIP. In particular visualizing the intersection region (showing both the minimum and maximal circles), showing landmarks, adding Google analytics, and looking at providing results from undns . Raja has added undns (a tool for guessing the location from the router name) for VTrace to TULIP and also to VTrace. it is not very successful.
PingER at SLAC
Les requested an update from Yahoo about TULIP's geolocation. They answered "We are very much interested in getting IP triangulation at internet scale, we will have internal sync-up on how we can leverage this initiative if there is rate limit and get back. Regarding opening up yahoo sites for deploying ping server requires some more time to discuss this with relevant stake holders with in yahoo." No word, sent a reminder 5/19/2014. No response 6/4/2014.
Les sent email to Google as follows: "I would like to bring to your attention that we have developed a geolocation tool using delay based (using RTTs from known ping server landmarks) distance estimates to triangulate the location of an IP host target. The tools is accessible at: http://www-wanmon.slac.stanford.edu/cgi-wrap/reflex.cgi. We have identified that the accuracy of the geolocation is directly related to the landmark density (e.g. # of landmarks/ million sq km). The higher the density the smaller the error and the fall off is exponential. We currently have over 1000 registered landmarks, of which at any given time ~300 are working. The tool not only finds the location of the target, it also gives an estimated error. To the best of our knowledge it is the only freely available delay based measurement geolocation service publicly available today. A drawback (compared to database methods such as those based on GeoMind) is the time taken to make the measurements. We have worked on this from many directions including parallelization of the ping requests, caching, tiering to get the rough location (i.e. region of the world) then zooming in using all landmarks in the region. We are putting together a publication on this."
