    2. Smokeping & PingER Integration: Shahryar (Asma is no longer working on this)
      1. Install at SLAC: Shahryar
        1. Install on test www server (it partially works): 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. The generation and presentation of the Smokeping graphs works
      2. Look at adding visualization of uptime: Asma
      3. Look at how to dynamically change the config file for Smokeping to accomodate the step interval (maybe time consuming, may affect all users and be cumbersome): Asma
      4. Will use as a top level access to PingER and also as links from Pingtable to display last 120 days using smokeping: Shahryar
    3. Provide real time access to cached data
      1. Do for SLAC
        1. Decide on how to extend to other monitoring sites, try with NIIT: Akbar, Umer
        2. Hassan is looking into the code sent by Fawad (next step is to get ML web services client to get data): Akbar, Hassan
    4. Ping-data.pl form only shows beacons.
      1. Need to point $sites_fn to pinger.xml instead of beacons.txt & check if the file is xml or flat (for backward compatibility): Shahryar
    5. Monitoring Hosts:
      1. Pakistan hosts
        1. PERN does not ping and reverse traceroute server is down (need to decide whether to give up on this host and remove it from our list of hosts to use for PingER and TULIP, awaits presentation to PERN/NTC, presentation to PERN made by Les 3/15/07, they are agreeable, need to move forward, Azher and Arshad are working the issue with Anwar 3/29/07, 4/7/07): Azher

        2. Mexico down emailed 4/7/07 [Fixed 4/9/07]: Les

        3. Brunsvigia stopped responding to ping_data.pl as of 4/3/07, reported by email 4/4/07 and 4/7/07 [working 4/10/07]: Les & brunsvigia

Triangulate position of an unknown host (see http://www.slac.stanford.edu/comp/net/wan-mon/tulip,Faran Faran expects to be able to devote more effort to this following 25th Jan 2007): Faran, Les

  1. Deployment: Faran
    1. Look into Mathematics of Singular Vector Decomposition technique. (agreed 11/16/06): Faran
  2. Improve web page

    1. Should the tables at NIIT web site be able to re-size themselves horizontally [The images do not work right in this case]: Faran

  3. Visualization

    1. Make tables sortable (working on 5/25/06, re-agreed 8/3/06, re-requested 8/21/06, done for the RTTs 8/22/06, can we do with buttons for all columns, agreed 2/27/07) [Done 3/22/07]: Faran

    2. Provide documentation (in progress 2/27/07, documented maths of selection 3/20/07, needs updating, agreed to update 3/22/07): Farhan, Faran
    3. Can we add AS's to routes: Yee, Faran
    4. DiscoveryStatistics =>LandMark Analysis one gets SLAC with RTT 0.0 regardless (reported 3/20/07): Faran

    5. If ping fails in Looking Glass Sites it shows as -5.0 RTT, should show as NAN (agreed 3/5/07, re-reported 3/20/07) [Done 3/22/07]: Faran

    6. When one double clicks on a row in Ping Results and the ping fails (e.g. host not responding) nothing shows in the  pop-up window. I think some diagnostic  or something should show (reported 3/20/07, re-reported 3/9/07 try Umich shows NAN for http://gate01.aglt2.org/cgi-bin/traceroute.pl?function=ping&target=203.99.50.204): Faran
    7. Add diagnostic to Sites.txt to identify bad formatting: Faran

  4. Evaluate whether using traceroute data helps (Suggested by Umar & Les 2/26/07): Faran
  5. Landmarks
    1. Get more landmarks for TULIP:
      1. China (sent email to ctsnet 7/26/06, reminded 12/6/06, 1/27/07): Les
      2. Try and get sites in Africa (Les sent email 11/28/06): Les
      3. COMTEC, Japan (Faran send email reminder 5/25/06, agreed to send another reminder 6/7/06, Umar will check with Farooq 11/16/06, Umar sent email reminders, latest 4/7/07): Faran, Farooq
      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, suggest case study on S.E. Asia): Umar
    2. Add NetDiGi route servers (asked for 8/30/06, is able to parse them, will look at adding appropriate hosts 3/22/07): Faran

    3. Modify TULIP to resolve names to IP addresses before calling landmarks [Done 4/10/07]: Faran

    4. Brunsvigia appears not to accept names (sent email to S. Africa with what is broken 3/26/07, asked again 4/10/07): Les
  6. 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
  7. Analysis

    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
    8. For US compare Faran's algorithm with Octant (no longer available 2/27/07), GeoIP & simple triangulation for PingER hosts(in progress 2/1/07)
      1. Confidence estimates
      2. Applied to PingER hosts
      3. Outside triangles, area coverage
      4. Effect/need to vary alpha: Faran
      5. Look at big discrepancies
