    4. Ping-data.pl form only shows beacons.
        Wiki Markup-Document in FAQ \[Done 2/20/07\]: Les-
      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
      2. Added item to FAQ to cover: Les
    5. Monitoring Hosts:
        Monitoring Hosts:
        1. NTC hosts, they agreed to install PingER2 at their 3 backbone sites (NTC management has changed, NIIT shifted from NTC to PERN, does not look promising): Arshad, Azher
        2. Pakistan hosts
          1. Wiki Markup
            -NTC is down since Oct 17th (-{_}{-}NTC management has changed, Arshad will contact upper management 12/4/06{-}{_}{_}-)-_ -\[After talking to NTC does not sound likely this will be restored, 1/11/07\]: Azher, Jerrod-
          2. PERN does not ping and reverse traceroute server is down (need to decide whether to give up on this host and remove it 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): AzherPERN would like to provide own archive analysis host (Les has sent URL describing tools needed on archive/analysis host, it maybe that iepm-bw would be more useful to them, however installing iepm-bw is non-trivial, or revive the real time PingER plots):): Azher
          3. Wiki Markup
            -Mexico down emailed 4/7/07 \[Fixed 4/9/07\]: Les-

    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. Wiki Markup
        -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. Wiki Markup
        -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. Wiki Markup
        -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): Faran% complete location window needs information to say pings done but traceroutes still in progress (, re-reported 3/20/07): 9/07 try Umich shows NAN for http://gate01.aglt2.org/cgi-bin/traceroute.pl?function=ping&target=203.99.50.204):Image Added Faran
      7. Add diagnostic to Sites.txt to identify bad formatting: Faran
      8. When zooming maintain size of dots (should we use Google maps, keep as a wish list item 2/27/07Faran will propose as a student project):  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. Brunsvigia appears not to accept names, need to modify TULIP to call with addresses (requested fix to TULIP 3/26/07, sent email to S. Africa with what is broken 3/26/07): Faran
    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
      1. Literature search on triangulation, multi-lateration: Faran
      2. Wiki Markup
        -Measure landmarks from landmarks \[Done 2/15/07\]: Faran-
      3. Optimize alpha by landmark (after have new location algorithm working, will try 1:2 for US, 1:3 for Europe, 2:15 Africa) : 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
      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
    8. Analysis of Accuracy and applicability

      2. Effect of removing, adding landmarks, try for Bolivia: Faran
      3. Provide bubble maps of accuracy: Faran

      5. Document anomalies  (e.g. root-servers): Faran
      6. Show accuracy by region and country: Faran
      7. Come up with a way to estimate the accuracy/confidence of estimates: Faran
        1. Document in the TULIP web page: Faran
    9. Find out more about GeoIP Tools
