    2. Smokeping & PingER Integration: Shahryar (Asma is no longer working on this)
      1. Install at SLAC: Shahryar
        1. Installation on test www-dev test server : Shahryar, Les
        2. Set up cronjobs (awaits SelectSrcDest.pm running from any pwd, also need to find out how long it takes to run)
        3. Needs to set the cron job on a Solaris machine. Shahryar, Les
        4. Carried out detail performance analysis of the code. Tried to make the code run faster, by eliminating unecessary instructions. The details of the performance analysis can be found at https://confluence.slac.stanford.edu/display/IEPM/PingER+Smokeping+Integration. We have decide it to run for SLAC only hosts in order to test it for the time being. The results of the analysis shows that it takes 2 hours on average to update all the (536 SLAC to rest of the world RRDs) and will consume approximately 250 MB of disk space.
        5. The generation and presentation of the Smokeping graphs works
      2. Make documentation point to Asma's detaile reference documentation too: Shahryar
      3. Look at adding visualization of uptime (Umar will check with Asma about uptime 4/30/07): Shahryar, Asma

    4. DiscoveryStatistics =>LandMark Analysis need to identify which Site number is displayed (i.e. from which window): Faran

    6. When one double clicks on a row in Ping Results and the ping fails (e.g. host timeout) wrong host shows up in window (e.g. RNP instead of COMTEC) : Faran
    7. Sites.txt
      1. Add diagnostic to Sites.txt to identify bad formatting: Faran
      2. Allow alpha to change (lot of work, many changes, will improve greatly, changes design, Faran focussing on 4/12/07)

        1. Account - tuliplandmark - is available at 'ias.comtec.co.jp' Faran will configure the webserver and deploy the scripts for both TULIP and PingER. (Umar will make an attempt to do the same, needs root to start web server 4/30/07).
      4. Add traceroute/Looking Glass servers in critical areas, if they have a common format (asked for 11/15/06, Les did a manual look at traceroute.org and found about 20 potential landmarks 11/17/06, Faran not clear if one can automate 2/27/07, several are automateable, to prove it Les has added 8, Faran will work on, re-requested 3/26/07 with suggestions): Faran
      5. Get site in Korea (made contact, test case works, contacted Prof 4/12/07, hope to have web server by May 4th, Arshad may visit): Umar

    5. sfsmds2.nsnl.net not responding (sent email 4/12/07, started responding but hostname incorrect, tried to fix now not responding 4/29/07, sent email): Les
  5. Apply to PingER node database to check the lat/longs are roughly correct (tried with 300-400 sites but cannnot get results due to fragile Internet at NIIT, will interact with Akbar to make tests at SLAC 8/31/06, exchanged emails on list of PingER hosts to locate 9/3/06): Faran

    4. Document Faran's algorithm, try new algorithm that does not require destination to be inside triangle: Faran, Umar
    5. Analyse the effect of passing IP addresses to landmarks rather than names: Faran
    6. Look at impact of increasing number of pings for getting accurate min_RTT (Faran measured for a few sites, Les gave ideas on how to extend and analyze for multiple sites, could be a major project 4/4/07): Faran
    7. Compare with GeoIP Tools

      1. Find a case where TULIP beats GeoIP Tool [Done 4.68.116.16, probably backbone routers too]:
