  • Progress on ICFA Report 2011 - Zafar
  • Amber is working on the Pakistani Case study. Can't backtrack to get the traceroutes earlier so its hard to understand the high values of RTT early in the year.
    • We need to start taking and archiving traceroutes between Pakistani monitoring hosts on a regular bases. This is still pending, will set this up asap.
    • There  There is an explanation for differences at the end of the year. A summary of the case study will go in the ICFA report.
  • Large RTTs seen between Islamabad and UET TaxilaUETTaxila. See https://confluence.slac.stanford.edu/display/IEPM/SEECS+to+UET+Taxila+link
    • Need to run a Running long series of pings (a week) of pings to look for signature for extended ping times1 week, 10 pings every 10 minutes). Amber will generate graphs to uncover the trends.
    • Need to get TCP configuration parameters fro for transmit and receive buffer lengths at end sites, and also at edge routers.
  • Need table of monitors vs remote sites for Pakistan. Do for a typical month, e.g. November. Amber will include this in the case study.
  • Need a trend plot Jun-Dec 2010.
  • Need number of hosts etc, see https://confluence.slac.stanford.edu/display/IEPM/Results+for+2010. Add this to Pakistani case study.

PingER

  • 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
  • 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.
  • Les and Umar worked on UNSW, and Les worked on South African Monitoring hosts, updating traceroute.pl and ping_data.pl. Both now work. In addition extensions were made to ping_data.pl to assist in debugging problems. Also fixed Brazil host. This is working fine.
  • PingER archive site: Database ERD being currently designed and tested.
Added Features for pinger map - Faisal
  1. Next he will add 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 will send the reflector/eventhandler, tulip-viz.cgi, Faisal will send the Java code to Zafar. 
  • Les spotted an error in reflector.cgi when using function=landmarks and requesting a csv file. Zafar has fixed.
  • Two new landmarks have been added in Taiwan.

...

  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! 
  3. Internet2 Joint Techs meeting at the end of Jan. Can Pak PerfSONAR nodes be up by then?

Possible projects

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

...

  • Les is trying to clear space to visit SEECS in February. Current plans are to arrive 2/13/2011, and leave the on the 2/22/2011.
  • The draft letters of invitation for Sadia and Amber have been submitted to upper management at SLAC.
  • The account requests for Bilal, Amber & Sadia have been submitted. I will send the passwords today.
    • They need to learn Perl. Zafar explained PingER and PerfSONAR projects in a nutshell to Amber and Sadia.
  • Zafar received his DS-2019 on Dec 10 (Fri). Applied for visa on Dec 13 (Mon). Interview date was Jan 3, it has been delayed.
  • Adnan Kiani has just been introduced to the PingER project. He completed his PhD degree this year in communications at Brunel University. He will be taking over the liaison at SEECS from Anjum.&
  • Arshad coming to SLAC in Jan, to start his daughter at Foothill. Falsal looking for a place for them
