- Visualization
Wiki Markup -Make tables sortable (working on 5/25/06, re-agreed 8/3/06, re-requested 8/21/06, done for the RTTs 8/22/06, can we do with buttons for all columns, agreed 2/27/07) \[Done 3/22/07\]: Faran-
- Provide documentation (in progress 2/27/07, documented maths of selection 3/20/07, needs updating, agreed to update 3/22/07): Farhan, Faran
- Can we add AS's to routes: Yee, Faran
- DiscoveryStatistics =>LandMark Analysis one gets SLAC with RTT 0.0 regardless (reported 3/20/07): Faran
Wiki Markup -If ping fails in Looking Glass Sites it shows as \-5.0 RTT, should show as NAN (agreed 3/5/07, re-reported 3/20/07) \[Done 3/22/07\]: Faran-
- When one double clicks on a row in Ping Results and the ping fails (e.g. host not responding) nothing shows in the pop-up window. I think some diagnostic or something should show (reported 3/20/07, re-reported 3/9/07 try Umich shows NAN for http://gate01.aglt2.org/cgi-bin/traceroute.pl?function=ping&target=203.99.50.204): Faran
- Sites.txt
- Add diagnostic to Sites.txt to identify bad formatting: Faran
- Allow alpha to change (lot of work, many changes, will improve greatly, changes design, Faran focussing on 4/12/07)
- Change Sites.txt to add extra column for alpha (done at NIIT): Faran
- Look at using PingER historical data to optimize alpha (agreed 4/12/07): Faran
- Make project to provide a u user interface to Sites.txt (Adnan may have a student from his presentation)
- Make Sites.txt not available from the web (the URL in http://www.slac.stanford.edu/comp/net/wan-mon/tulip/ is no longer an active URL, however the file is still accessible from teh web, need to work with Faran to move it): Les, Faran
- When zooming maintain size of dots (Faran will propose to Umar as a student project 4/10/07, he is concerned about teh download time, Asif suggests using NASA images for Java platform, will send link 4/12/07): Faran
- Evaluate whether using traceroute data helps (Suggested by Umar & Les 2/26/07): Faran
- Landmarks
- Get more landmarks for TULIP:
- 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
- COMTEC, Japan (Faran send email reminder 5/25/06, agreed to send another reminder 6/7/06, Umar will check with Farooq 11/16/06, Umar sent email reminders, latest 4/7/07, Farooq has been sick and unable to communicate, we need an account there 4/12/07): Faran, Farooq
- Account - tuliplandmark - is available at 'ias.comtec.co.jp' Faran will configure the webserver and deploy the scripts for both TULIP and PingER. (Umar will make an attempt to do the same).
- Add traceroute/Looking Glass servers in critical areas, if they have a common format (asked for 11/15/06, 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
- Get site in Korea (made contact, test case works, suggest case study on S.E. Asia, sontacted contacted Prof waiting to hear back 4/12/07): Umar
- Add NetDiGi route servers (asked for 8/30/06, is able to parse them, will look at adding appropriate hosts 3/22/07): Faran
Wiki Markup -Modify TULIP to resolve names to IP addresses before calling landmarks \[Done 4/10/07\]: Faran-
- Brunsvigia appears not to accept names (sent email to S. Africa with what is broken 3/26/07, asked again 4/10/07): Les
- sfsmds2.nsnl.net not responding (sent email 4/12/07): Les
- Get more landmarks for TULIP:
- Apply to PingER node database to check the lat/longs are roughly correct (tried with 300-400 sites but cannnot get results due to fragile Internet at NIIT, will interact with Akbar to make tests at SLAC 8/31/06, exchanged emails on list of PingER hosts to locate 9/3/06): Faran
- Analysis
- Literature search on triangulation, multi-lateration: Faran
Wiki Markup -Measure landmarks from landmarks \[Done 2/15/07\]: 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
- Document Faran's algorithm, try new algorithm that does not require destination to be inside triangle: Faran, Umar
- Analyse the effect of passing IP addresses to landmarks rather than names: Faran
- Look at impact of increasing number of pings for getting accurate min_RTT (Faran measured for a few sites, Les gave ideas on how to extend and analyze for multiple sites, could be a major project 4/4/07): Faran
- Compare with GeoIP Tools
- For US compare Faran's algorithm with Octant (no longer available 2/27/07), GeoIP & simple triangulation for PingER hosts(in progress 2/1/07)
- Confidence estimates
- Applied to PingER hosts
- Outside triangles, area coverage
- Effect/need to vary alpha: Faran
- Look at big discrepancies
- Analysis of Accuracy and applicability
- Accuracy vs known locations (landmarks & PingER hosts): faran
- Effect of removing, adding landmarks, try for Bolivia: Faran
- Provide bubble maps of accuracy: Faran
- What area/population is covered by TULIP
- Document anomalies (e.g. root-servers): Faran
- Show accuracy by region and country: Faran
- Come up with a way to estimate the accuracy/confidence of estimates: Faran
- Document in the TULIP web page: Faran
- Find out more about GeoIP Tools
Wiki Markup Find a case where TULIP beats GeoIP Tool \[Done 4.68.116.16, probably backbone routers too\]:
