  • I am still working on a monitor in Sarawak. It was using Linux selinux that blocks pings & traceroutes. That has been disabled. Now the webserver is down.
  • [http://www-wanmon.slac.stanford.edu/cgi-wrap/reflector.cgi?PD=set&PE=set&function=landmarks&out=csv|http://www-wanmon.slac.stanford.edu/cgi-wrap/reflector.cgi?PD=set&PE=set&function=landmarks&out=csv] has been modified by Zafar to allow the use of tsv instead of csv since there may be commas in the city field.
  • Zafar fixed the bug in the SEECS table.pl that was messing up the hostname.
  • Sadia, Amber and Zafar have found differences in the values reported by table.pl and pingtable for a given archive site, and in the values reported by pingtable.pl at SEECS and SLAC. This has been explained and documented, see https://confluence.slac.stanford.edu/display/IEPM/Anomalies
  • Fahad made some small changes to http://www-wanmon.slac.stanford.edu/cgi-wrap/checkremote.cgi. He will add some help and also an allyearly tick. It looks quite useful.
  • I modified pinger_country_metrics.pl at http://www-iepm.slac.stanford.edu/pinger/pcm.html to enable it to use the allyearly data. This helps throughput calculations since losses are more accurately measured
  • I am putting together a talk on "Quantifying the digital Divide: the emergence of Africa" for the American Physical Society in April.

  1. Faisal is working with Yee. No Progress
    1. Looking at how to display multiple nodes at a single lat/long or close lat/longs, a grouping problem. Looking at how to handle identical lat/longs. Looked at MonALISA, and other implementations. This has been solved. 
    2. Added Zoom in based on selection feature. User can select a specific region of a map by holding shift key and dragging through the bounds. Will add to the PingER maps.
    3. For displaying links between hosts, Faisal is using poly-lines to represent great circle routes, rather than just straight lines to present the actual shortest path. Lot of mathematical formulas. Study on implementing Bézier curves which may help better to separate paths.
    4. Representation of data in XML for links and paths. Writing an API so can get data from perfSONAR and provide to the client.
  2. Zafar - deploy PerfSONAR nodes at SEECS. Second step is to find whether the same can be done at HEC on PERN's network. It is working, congratulations! 

Possible projects

Wiki MarkupSee \ [https://confluence.slac.stanford.edu/display/IEPM/Future+Projects\]. Zafar will talk to the students about these projects.

  1. Extend the NODEDETAILS data base to allow entry support for whether the host is currenty pingable. 
  2. Wiki MarkupExtend Checkdata to provide emails automatically, see \see [https://confluence.slac.stanford.edu/display/IEPM/Extend+checkdata+to+make+it+more+useful\]. Many of the ides in the script node-contacts.pl are a step in this direction.unmigrated-wiki-markup
  3. Add *MOS and alpha to pingtable.p{*}l see \ [https://confluence.slac.stanford.edu/display/IEPM/Add+Mean+Opinion+Score+%28MOS%29+to+pingtable.pl+metrics\]  Sadia will start work on it when done with HEC report,  writing thesis. *When should we expect progress, don't forget alpha? No started yet.*]  Sadia will start work on it when done with HEC report,  writing thesis. When should we expect progress, don't forget alpha? No started yet.
  4. Improve the PingER2 installation procedures to make it more robust. This might be something for the person(s) in Pakistan who are responsible for installing PingER2 at the Pakistani monitoring sites. They probably have found where the failures occurs. Also look at the FAQ, and ping_data.pl which has been improved to assist in debugging, could it be further improved (e.g. provide access to the httpd.conf file so one can see if it properly configured)? There are 2 students working on the PingER archive. *Is this something they could work on?*
  5. Fix PingER archiving/analysis package to be IPv6 conformant. Will build a proposal for an IPv6 testbed. They will try various transition techniques. A proposal has been prepared and that has been submitted to PTA. Adnan is a co PI. It is being evaluated today.  A small testbed has been established in SEECS and thve plan to shift some of the network to IPv6. Bilal is part of 3 students involved with PingER and they will be involved with IPv6. They are porting the PingER archive site site to using a database. They have redeveloped the archive site using Umar's documentation. They have set up a small test archive site. They have gathering, archiving, analysis. They will design a new database. They will also try a port of PingER to IPv6.
