1. Deployment: Faran
   1. Provide a program API: Faran, Shahryar (dropped)
   2. Refine the list in Sites.txt by writing a script that will run TULIP HTTP requests to ping to see which landmarks are not responding (agreed 11/16/06, do we really need it, if so can we reduce its priority): Faran
   3. Provide opotion so that Sites.txt can be modified from TULIP. (agreed 11/16/06, currently the master is kept at SLAC and one has to logon to SLAC to modify it): Faran
   4. Ignore comments in mid line (agreed 11/30/06, is it done 1/31/07): Faran
   5. Look into Mathematics of Singular Vector Decomposition technique. (agreed 11/16/06): Faran
   6. SLAC account for Faran (Faran need to report if password changed): Faran
2. 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): Faran
   2. Can we add AS's to routes: Yee, Faran
   3. Integrate with Google maps: Faran
   4. When zooming maintain size of dots:  Faran
3. Landmarks
   1. Get more lanmarks for TULIP:
      1. Sent email Latin America (5/7/06, 11/25/06): Les
         1. Follow up on positive response from CUDI Mexico (reminded 1/12/07, it is there but still await the URL, sent reminder 1/27/07): Les
      2. China (sent email to ctsnet 7/26/06, reminded 12/6/06, 1/27/07): Les
      3. Try and get sites in Africa (Les sent email 11/28/06): Les
      4. 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
      5. 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
   2. Add NetDiGi route servers (asked for 8/30/06): Faran
   3. Provide tool to geolocate all PingER sites, analyze results to see what landmarks never respond; Faran
   4. Problem Landmarks:
      1. pinger.ntc.net.pk denies accesss (email to Azher & Faran 7/25/06, Azher responded that he is checking 7/27/06, email sent again 8/21/06, Azher knows about will send person to repair 8/22/06) see also above for the PingER node at this site: Faran/Azher
      2. Enable landmarks that only work for IP addresses: Faran
4. 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
5. Analysis
   1. Literature search on triangulation, multi-lateration: Faran
   2. Compare with GeoIP tools: Faran
   3. Measure landmarks from landmarks: Faran
   4. Document Faran's algorithm, try new algorithm with optimized alpha 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. Compare Faran's algorithm with Bamba's, Octant & simple triangulation
      1. Contact Bamba to find out if http://planetlab-01.ipv6.lip6.fr:10000/cbg.php works for any sites (email send 4/21/06): Aziz
      2. Confidence estimates
      3. Applied to PingER hosts
      4. Outside triangles, area coverage
6. Analysis of Accuracy and applicability
   1. Accuracy vs known locations
   2. Effect of removing, adding landmarks, try for Bolivia:Faran
   3. Comparison with other sets of landmarks & methods (can't do Bamba since it is down), Octant, NetGeo for accuracy coverage etc.
   4. Provide bubble maps of accuracy: Faran
   5. Review difference between Guthrie and TULIP
      1. For US using Octant: Faran
      2. Look at big discrepancies: Faran
      3. Compare with GeoIP: Faran
   6. What area/population is covered by TULIP
   7. Document anomalies  (e.g. root-servers): Faran
   8. Show accuracy by region and country: Faran
   9. Come up with a way to estimate the accuracy/confidence of estimates: Faran
      1. Document in the TULIP web page: Faran
