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

  1. Visualization 
    1. When zooming maintain size of dots (having problems with x,y to longitude hope to fix in 8/28/07, and will show results, Rehan unable to meet deadlilnes, still in progress, Faran will work on 8/30/07):  Faran
      1. Does the viz make sense when >= 60 nodes (PlanetLab) in US: Faran
    2. Need a way to display alphas used: Faran
  2. Bugs:
    1. Traceroute Results table does not sort when clicking on column headings (7/5/07): Faran
    2. Site list table does not sort on table headings (report 8/16/07, probably will not fix since it messes up other things, so will await desperate documented case): Faran
    3. Site list does not edit correctly (reported 8/17/07, may be related to sorting 8/23/07): Faran
    4. Sno in Confidence Estimates not correlated with Landmarks.
    5. How do Sno correlate when there are landmarks from SLAC and PlanetLab?
    6. Confidence Estimates table does not sort on table heading: faran
    7. Location History needs headings or something to explain what the columns are: Faran
  3. Clarifications
    1. How are the confidence estimates arrived at, why are they sometimes -ve, e.g. Milan to CERN (Faran will look at 8/30/07)
  4. 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. Add traceroute location and GeoIP Tool: Faran
      1. Find replacement for GeoIP tool: Faran, Shahryar
    5. Logs
      1. Add log of failures, successes (7/11/07) (thinking about it 8/9/07, awaits CGI reflector 8/23/07): Faran
    6. Add results from GeoIP: Faran
    7. Add tiering  it is needed to allow scaling to large numbers of landmarks  (7/6/07): Faran
      1. Need a State column adding to the Sites List so can have tier 0 and 1 hosts and even Disable hosts without losing information (7/5/07), Faran looking at how to implement 7/26/07): Faran
        1. Decide whether to use PlanetLab as tier1 and others as tier0 (may be problem that will not have PlanetLab hosts in developing countries): Faran

      2. Research effectiveness of tiering [Done for N America & Europe]: Shahryar, Les

    8. Use proxy for making landmark requests (for log auditing, blocking, PlanetLab cookie) (7/6/07): Shahryar, Faran
      1. CGI script

        1. Look at various ways to do asynchronous I/O [Done 8/30/07]: Shahryar

        2. Limit number of CGI scripts running [Done 8/30/07]: Shahryar

        3. Add black list support [Done 8/30/07]

        4. Get approved by SLAC security (submitted 8/20/07) [Done 8/30/07]: Shahryar

        5. Install CGI script at NIIT on MAGGIE2 (are all Perl Libs installed?): Faran
        6. Show initial version at NIIT 8/24/07: Faran
        7. Install at SLAC: Shahryar
  5. Landmarks

    1. Filter so do not have multiple PlanetLab hosts at one site (lat/long) [Done 8/31/07]: Shahryar

    2. Append PL to each PlanetLab host in Sites.txt: Shahryar
    3. Send Sites.txt to Faran: Shahryar
    4. Enable comments in Sites.txt file and indicate how created: Shahryar, Faran

    5. Make available as URL [Done 8/30/07]: Les

    6. 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, have site in Democratic Republic of Congo 8/23/07): Les
      3. Try to get landmarks in Argentina and Chile: Les
  6. Analysis (need for examination 5/31/07)
    1. Provide API (agreed 6/28/07, changes to TULIP mean current API is not working): 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
    5. Make help document available as wiki: Faran, Les
    6. Compare with GeoIP Tool & Hostip.info

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

      2. Compare with MaxMind (see http://www.maxmind.com/app/geolitecountry): Faran
      3. Document comparison in Wiki (is this done?): Shahryar
      4. Confidence estimates of accuracy
      5. Applied to PingER hosts
      6. Outside triangles, area coverage
      7. Effect/need to vary alpha: Faran
      8. Look at big discrepancies
    7. Provide bubble maps of accuracy: Faran
    8. What area/population is covered by TULIP
    9. Show accuracy by region and country: Faran
  7. 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
    5. Put Faran's final year project documentation online: Faran, Umar
