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):  Faran, Rehan
    2. Does the viz make sense when >= 60 nodes (PlanetLab) in US: Faran
    3. Need a way to display alphas used: Faran
  2. Bugs:

    1. Sorting on header in Site Lists does not work (7/3/07) [Done 8/9/07]: Faran

    2. Traceroute Results table does not sort when clicking on column headings (7/5/07): Faran

    3. Reduce size of Traceroute Results pane now traceroute is not done automatically (agreed 7/26/07, agreed 8/9/07) [Done 8/17/07]: Faran

    4. 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
    5. Site list does not edit correctly (reported 8/17/07, may be related to sorting 8/23/07): Faran

    6. Check version number works [Done 8/23/07]: Les

    7. Entries in the Site List need correcting (reported 8/16/07): Faran
  3. Improvements
    1. Allow alpha to change (lot of work, many changes, could improve, need analysis & understanding*)*

    2. Left hand pane labeled Looking Glass, should be Landmarks [Done 8/9/07]: Faran

    3. Look at using PingER historical data to optimize alpha (agreed 4/12/07): Faran
    4. Evaluate whether using traceroute data helps (Suggested by Umar & Les 2/26/07, could add 3 more RTTs to minimize from): Faran
    5. Add traceroute location and GeoIP Tool: Faran
      1. Find replacement for GeoIP tool: Faran, Shahryar
    6. Logs
      1. Review logs to see if complete (awaits the CGI reflector): Faran, Les
        1. Add timestamps, make sortable with offsets (7/9/07, Faran said done but not working at SLAC 8/9/07, clarifying requiremenst with examples 8/17/07): Faran

        2. Add IP address [Done for Source 8/17/07]: Faran

        3. Make log file comma separated values (requested 8/16/07, specified what is needed 8/17/07, Faran concerned it may make things run slow 8/23/07): Faran
      2. Add log of failures, successes (7/11/07) (thinking about it 8/9/07, awaits CGI reflector 8/23/07): Faran
    7. Add tiering (need 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: Shahryar
        2. Limit number of CGI scripts running: Shahryar
        3. Get approved by SLAC security (submitted 8/20/07): Sharyar
        4. Install CGI script at NIIT om MAGGIE2 (are all Perl Libs installed?): Faran
        5. Show initial version at NIIT 8/24/07: 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, have site in Democratic Republic of Congo 8/23/07): Les

      3. Add traceroute/Looking Glass servers in critical areas, if they have a common format (asked for 11/15/06). Nothing useful inhttp://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) [Done will implement with CGI reflector 8/23/07] : Faran

      4. Try to get landmarks in Argentina and Chile: Les
  5. 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, U
    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. Compare with MaxMind (see http://www.maxmind.com/app/geolitecountry): Faran
      3. Document comparison in Wiki: 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
    6. Provide bubble maps of accuracy: Faran
    7. What area/population is covered by TULIP
    8. Show accuracy by region and country: 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
    5. Put Faran's final year project documentation online: Faran, Umar
