Triangulate position of an unknown host (see http://www.slac.stanford.edu/comp/net/wan-mon/tulip,Faran): Faran, Les
- Visualization
- Extend to enable others to contribute to tool: Faran
- Sites.txt
- Need to be able to edit existing sites: Faran
-
- 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
- Add help and/or example on how to enter data: Faran
-
- Need to be able to edit existing sites: Faran
- 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
- Need a way to display alpha used: Faran
- Bugs:
- Left hand pane labeled Looking Glass, should be Landmarks.
- 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
- Add version number and date to Help about (agreed 6/28/07): Faran
- 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 rigtht nothing happens (added 7/3/07): Faran
- 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
- Madrid needs to be correctly located (7/3/07): Faran.
- Improvements
- Allow alpha to change (lot of work, many changes, could improve, need analysis & understanding*)*
- Look at using PingER historical data to optimize alpha (agreed 4/12/07): Faran
- Evaluate whether using traceroute data helps (Suggested by Umar & Les 2/26/07, could add 3 more RTTs to minimize from): Faran
- Landmarks
- 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.:
- China (sent email to ctsnet 7/26/06, reminded 12/6/06, 1/27/07): Les
- Try and get sites in Africa (Les sent email 11/28/06): Les
- 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
- Look into PlanetLab (18 China, 6 Brazil, 2 Uruguay, 2 Puerto Rico): Shahryar, Faran
- Create script to send that will do pings: Shahryar
- Shahryar will send information to Faran 6/28/07: Shahryar
- Integrate script with TULIP: Faran
- Decide how and if to use Europe and US sites: Faran
- Consider allowing user to ask for more detailed information by a second pass using regional landmarks: Faran
- Add NetDiGi route servers (asked for 8/30/06, is able to parse them, will look at adding appropriate hosts 3/22/07): Faran
- 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.:
- Analysis (need for examination 5/31/07)
- Provide API (agreed 6/28/07): Faran
- Literature search on triangulation, multi-lateration: Faran
- 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
- Document Faran's algorithm, try new algorithm that does not require destination to be inside triangle: Faran, Umar
- Compare with GeoIP Tool & Hostip.info
Find cases where TULIP beats GeoIP Tool [Done 4.68.116.16, probably backbone routers too]:
- Confidence estimates of accuracy
- Applied to PingER hosts
- Outside triangles, area coverage
- Effect/need to vary alpha: Faran
- Look at big discrepancies
- Provide bubble maps of accuracy: Faran
- What area/population is covered by TULIP
- Show accuracy by region and country: Faran
- Document in the TULIP web page: Faran
- Look at publication (helps advance Faran's career and possibly "best project", will need more analysis)
- Find conference: all
- Can we get Cisco interested?: Arshad, Faran
- Update documentation: Les, Faran
- Read paper at http://research.microsoft.com/%7Epadmanab/papers/sigcomm2001.pdf: Faran
