- Visualization
- 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

- Bugs:
- Traceroute Results table does not sort when clicking on column headings (7/5/07): Faran
- 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
- Site list does not edit correctly (reported 8/17/07, may be related to sorting 8/23/07): Faran
- Sno in Confidence Estimates not correlated with Landmarks.
- How do Sno correlate when there are landmarks from SLAC and PlanetLab?
- Confidence Estimates table does not sort on table heading: faran
- Location History needs headings or something to explain what the columns are: Faran
- Change Ladnmarks to Landmarks on tab in Ping window (reported 9/21/07): Faran
- The map for Iterative Corrections does not seem ti fill until it is moved (9/21/07): Faran

- Can't look at Looking Glass/SLAC landmarks (9/21/07): Faran
- Clarifications
- How are the confidence estimates arrived at, why are they sometimes -ve, e.g. Milan to CERN (Faran will look at 8/30/07)
- 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
- Add traceroute location and GeoIP Tool: Faran
- Find replacement for GeoIP tool: Faran, Shahryar
- Logs
Add log of failures, successes (7/11/07) (thinking about it 8/9/07, awaits CGI reflector 8/23/07) [Done in reflector by Les]: Faran
- Add results from GeoIP: Faran
- Add tiering it is needed 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): Shahryar, Faran
- CGI script
Look at various ways to do asynchronous I/O [Done 8/30/07]: Shahryar
Limit number of CGI scripts running [Done 8/30/07]: Shahryar
Add black list support [Done 8/30/07]
Get approved by SLAC security (submitted 8/20/07) [Done 8/30/07]: Shahryar
- Install CGI script at NIIT on MAGGIE2 (are all Perl Libs installed?): Faran
- Show initial version at NIIT 8/24/07: Faran
Install at SLAC [Done 9/1/07]: Shahryar, Les
- Check if increasing timeout reduces failures:
- Integrate with TULIP: Faran
- CGI script
- Landmarks
Filter so do not have multiple PlanetLab hosts at one site (lat/long) [Done 8/31/07]: Shahryar
- Append PL to each PlanetLab host in Sites.txt: Shahryar
- Send Sites.txt to Faran: Shahryar
Enable comments in Sites.txt file and indicate how created [Done for reflector by Les]: Shahryar, Faran
Make available as URL [Done 8/30/07]: Les
- 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
- Add Hong Kong to landmarks (9/21/07): Faran
- Is IHEP in list?
- Try and get sites in Africa (Les sent email 11/28/06, have site in Democratic Republic of Congo 8/23/07): Les
- Try to get landmarks in Argentina and Chile: Les
- 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
- Make help document available as wiki: Faran, Les
- Compare with GeoIP Tool & Hostip.info
Find cases where TULIP beats GeoIP Tool [Done 4.68.116.16, probably backbone routers too]
- Compare with MaxMind (see http://www.maxmind.com/app/geolitecountry): Faran
- Document comparison in Wiki (is this done?): 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
