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
   7. % complete location window needs information to say pings done but traceroutes still in progress (reported 3/20/07): Faran
   8. When locating www.niit.edu.pk one of the Ping Results has no Country/Astate and a Ping Site www.niit.edu.pk&contact=cottrell@slac.stanford.edu&id=TULIP (reported 3/26/07): Faran
   9. When zooming maintain size of dots (should we use Google maps, keep as a wish list item 2/27/07):  Faran
4. Evaluate whether using traceroute data helps (Suggested by Umar & Les 2/26/07): Faran
5. Landmarks
   1. Get more lanmarks 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): 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): Faran
      5. Working on 2 sites in Palestine: Les

         1. Wiki Markup
            -Resolve traceroute: icmp socket: Permission denied (reported 2/27/07) \[Fixed 3/10/07\]: Les-

         2. Gaza Strip host is down, reported 3/21/07: Les

         3. Wiki Markup
            -Added Al Quds to landmarks \[Done 3/22/07\]: Les-

      6. 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 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
   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
   1. Accuracy vs known locations (landmarks & PingER hosts): faran
   2. Effect of removing, adding landmarks, try for Bolivia: Faran
   3. Provide bubble maps of accuracy: Faran
   4. What area/population is covered by TULIP
   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

   1. Wiki Markup
      -Faran make contact with GeoIP people \[Done 3/20/07\]: Faran-

   2. Wiki Markup
      Find a case where TULIP beats GeoIP Tool \[Done 4.68.116.16\]:
