  • I have extended ping_data.pl to provide more debugging capabilities, based on experience with UERJ, AMPATH and ACME.
  • No progress on a monitor in Sarawak. It was using Linux selinux that blocks pings & traceroutes. That has been disabled. Now the webserver is down
  • 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 am putting together a talk on "Quantifying the digital Divide: the emergence of Africa" for the American Physical Society in April.
  • PingER archive site: Database ERD being currently designed and tested.

Visualization pinger map - Faisal
  1. Colors for connected links
  2. Range and Colors configuration
  3. Layout revamp to provide more space for mapHas  added a control panel showing the color assigments and the ability to customize the colors. Added custom color range component.

TULIP

  • With the move to the new host Faisal had to get a new cookie to allow scriptroute to run scripts on the PlanetLab infrastructure. Still needs testing.
  • Get the MatLab license at SEECS and put up a CGB server using it. Do not have license for MatLab will do on own machines to test and will migrate when have license. Zafar will contact Arshad and Ali. Basically the client will call the reflector with the target. The reflector will return the landmarks and RTTs. The client will then call the CBG/MatLab server with the relevant RTTs, lat/longs etc.  Bilal has read the TULIP architecture. He has a moderate understanding of how it works. He is modifying CBG code. Now it is ready for integration with TULIP. I sent the reflector/eventhandler, tulip-viz.cgi, & Faisal sent the Java code to Zafar. - PROGRESS?

  1. Faisal is working with Yee. No Progress Looking at how to display multiple nodes at a single lat/long or close lat/longs, a grouping problem. 
    1. Arrows for tracerouts being implemented.
    2. Working with Yee to get Lat long of perfSONAR host corrected
      3. Looking at how to handle identical lat/longs. Looked at MonALISA, and other implementations. This has been solved. 
    3. 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.
    4. 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.
    5. 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!
  3. Internet2 Joint Techs meeting at the end of Jan. Can Pak PerfSONAR nodes be up by then?
