Triangulate position of an unknown host (see http://www.slac.stanford.edu/comp/net/wan-mon/tulip,Faran): Faran, Les
- Visualization
- 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 examine in two weeks 6/13/07, work in progress 7/26/07 faran is tracking Rehan's work, No progress 8/9/07): Faran, Rehan
- Need a way to display alphas used: Faran
- Bugs:
Sorting on header in Site Lists does not work (7/3/07) [Done 8/9/07]: Faran
- Traceroute Results table does not sort when clicking on column headings (7/5/07): Faran
- Reduce size of Traceroute Results pane now traceroute is not done automatically (agreed 7/26/07, agreed 8/9/07): Faran
- Site list table does not sort on table headings (report 8/16/07): Faran
- Entries in the Site List need correcting (reported 8/16/07): Faran
- Improvements
- Allow alpha to change (lot of work, many changes, could improve, need analysis & understanding*)*
Left hand pane labeled Looking Glass, should be Landmarks [Done 8/9/07]: Faran
- 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
- Add traceroute location and GeoIP Tool: Faran
- Find replacemnt for GeoIP tool: Faran, Shahryar
- Logs
- Review logs to see if complete: Faran, Les
- Add timestamps, make sortable with offsets (7/9/07, Faran said done but not working at SLAC 8/9/07: Faran
- Add IP address: Faran
- Make log file comma separtaed values (requested 8/16/07): Faran
- Add log of failures, successes (7/11/07) (thinking about it 8/9/07): Faran
- Review logs to see if complete: Faran, Les
- Add tiering (need to allow scaling to large numbers of landmarks) (7/6/07): Faran
- 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
- Decide whether to use PlanetLab as tier1 and others as tier0 (may be problem that will not have PlanetLab hosts in developing countries): Faran
Research effectiveness of tiering [Done for N America & Europe]: Shahryar, Les
- 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
- Use proxy for making landmark requests (for log auditing, blocking, PlanetLab cookie) (7/6/07): Faran
- CGI script
- Look at various ways to do asynchronous I/O: Shahryar
- Limit number of CGI scripts running: Shahryar
- Look at making the applet request next say 4 landmarks, await result and tell user etc.; Faran
- CGI script
- 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, plus lots in Europe and N. America, awaits Shahryar's CGI script 8/9/07): Shahryar, Faran
- Integrate CGI script with TULIP: Faran
- Will also need to ensure data is correct before making request: 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, changes to TULIP mean current API is not working): 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] :
- Document comparison in Wiki: Shahryar
- 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
- 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
- Put Faran's final year project documentation online: Faran, Umar
