Triangulate position of an unknown host (see http://www.slac.stanford.edu/comp/net/wan-mon/tulip,Faran): Faran, Les

  1. Visualization 
    1. Extend to enable others to contribute to tool: Faran
    2. Sites.txt
      1. Need to be able to edit existing sites: Faran
          1. Student working on it plan to be done by 6/10/07 (done needs install at SLAC & testing 6/13/07, the add new node seems to work, but editing does not seem to work, reported 6/28/07): Faran
        2. Add help and/or example on how to enter data: Faran
    3. When zooming maintain size of dots (Faran will propose to Umar as a student project 4/10/07, he is concerned about the download time, assigned to Rehan 5/10/07, has images, will be a separate jar file to reduce disturbance, Rahan hopes to start after exams on two weeks 6/13/07):  Faran, Rehan
    4. Need a way to display alpha used: Faran
  2. Bugs:
    1. Left hand pane labeled Looking Glass, should be Landmarks.
    2. SNos are not consistent pane to pane especially after sorting (reported 6/13/07, Faran never meant them to be the same, but has an idea on how to do it 6/28/07); Faran

    3. Add version number and date to Help about (agreed 6/28/07) [Done 7/3/07]: Faran

    4. Click on File>View Landmark Config File it asks for the password. If I enter it wrong it tells me it is wrong, if I enter it right nothing happens (added 7/3/07) [Done 7/3/07]: Faran

    5. Sorting (click on header Min RTT) in Ping Results pane 220 ms comes before 74ms (i.e. needs to be numeric sorting) (Added 7/3/07): Faran
    6. Madrid lat/long need to be correctly located (7/3/07): Faran.
    7. Sorting on header in Site Lists does not work (7/3/07): Faran
    8. Changing long for Madrid and then hitting Update List did not change the long after a reload (7/3/07): Faran
  3. Improvements
    1. Allow alpha to change (lot of work, many changes, could improve, need analysis & understanding*)*
    2. Look at using PingER historical data to optimize alpha (agreed 4/12/07): Faran
    3. Evaluate whether using traceroute data helps (Suggested by Umar & Les 2/26/07, could add 3 more RTTs to minimize from): Faran
  4. Landmarks
    1. Get more landmarks for TULIP, ideally need at least one landmark in all major developing countries that do not have direct connections to nearby countries.:
      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. Add traceroute/Looking Glass servers in critical areas, if they have a common format (asked for 11/15/06). Nothing useful in http://www.caida.org/analysis/routing/reversetrace/. 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 is having problems with blocking after several accesses, will get a list then will try and contact to open up 5/10/07, Les sent another list from traceroute.org of some potential sites in East Asia and E. Europe): Faran
      4. Look into PlanetLab (18 China, 6 Brazil, 2 Uruguay, 2 Puerto Rico): Shahryar, Faran
        1. Create script to send that will do pings: Shahryar
        2. Shahryar will send information to Faran 6/28/07: Shahryar
        3. Integrate script with TULIP: Faran
        4. Decide how and if to use Europe and US sites: Faran
          1. Consider allowing user to ask for more detailed information by a second pass using regional landmarks: Faran
    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
  5. Analysis (need for examination 5/31/07)
    1. Provide API (agreed 6/28/07): Faran
    2. Literature search on triangulation, multi-lateration: 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, done at NIIT, need to deploy at SLAC 4/10/07, Faran is worried about how to group nodes by region etc. and anomalies 6/13/07), hope to review results by 6/5/07): Faran
    4. Document Faran's algorithm, try new algorithm that does not require destination to be inside triangle: Faran, Umar
    5. Compare with GeoIP Tool & Hostip.info

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

      2. Confidence estimates of accuracy
      3. Applied to PingER hosts
      4. Outside triangles, area coverage
      5. Effect/need to vary alpha: Faran
      6. Look at big discrepancies
    6. Provide bubble maps of accuracy: Faran
    7. What area/population is covered by TULIP
    8. Show accuracy by region and country: Faran
      1. Document in the TULIP web page: Faran
  6. Look at publication (helps advance Faran's career and possibly "best project",  will need more analysis)
    1. Find conference: all
    2. Can we get Cisco interested?: Arshad, Faran
    3. Update documentation: Les, Faran
    4. Read paper at http://research.microsoft.com/%7Epadmanab/papers/sigcomm2001.pdf: Faran
