Invitees: Anjum+, Kashif, Raja+, Johari+, Nara, Abdullah, Badrul, Hanan, Fidah, Saqib+, Les+, Renan, Bebo

  • Renan is currently working on optimizing and measuring timing for  converting the data to RDF format.
  • He has data for allyearly, allmonthly and last 60days for all 10 metrics.
  • The crontabs to update the data are running pretty smoothly*
  • The pre alpha data is available publicly.
    * For the Linked Open Data / RDF which is in pre-alpha days, you can go to http://pingerlod.slac.stanford.edu. As can be seen this page is not ready for prime time. However the demos work as long as one carefully elects what to look at:
    • Click on Visualizations, there are two choices:
      • Multiple Network Metrics: Click on the image: gives a form, choose from Node pinger.slac.stanford.edu pinging to www.ihep.ac.cn, time parameters yearly, 2006 2012, metrics throughput, Average RTT Packet loss and display format Plot graph, then click on submit. In a few seconds time series graph should come up. Mouse over to see details of values at each x value (year).
      • A mashup of network metrics x university metrics Click on image: gives another form, pinging from pinger.slac.stanford.edu, School metric number of students, time metric years 2006 2012, display format plot graph, click on submit. Longer wait, after about 35 seconds a google map should show up. Click on "Click for help." Area of dots = number of students, darkness of dots = throughput (lighter is better), inscribing circle color gives university type (public, private etc.) Click on circle for information on university etc.

Johari needs a public DNS for his Raspberry Pie. Anjum suggested Johari move the Raspberry Pie to the data center based on SEECS experiences with Load Balancers. This may also assist with the traceroute problem and make it easier to get a public DNS. Update Johari

Saqib is starting to look at Pingtable.pl anomalies as a start in a case study for Malaysia and S.E Asia. In particular hosts which are unreliable, hosts with large (>1) values of Directivity, host with large RTTs, hosts with  large unreachability or losses etc. Saqib has been busy with thesis so no progress, will be available June 12th on.  Les had some questions on the locations of some sites that have impossible values of Directivity. One has been Disabled, any word on Allianze? What about QIUP? Saqib will investigate. Update. Saqib was not at the previous meeting meetings so there was no update. There was no representative for UTM at this meeting either. 

Hossein Javedani of UTM was interested in anomaly detection in PingER data. We have sent him a couple of papers and how to access the PingER data. Any update - Hanan, Saqib?

...

Badrul sent a paper to Saqib yesterday a few weeks ago on event correlation. They plan to have a draft out in the next 2-3 weeks..

Raja will be arriving arrrived at SLAC around August 21st, 2013. He is in Californiaand is busy.

TULIP - Raja

Raja has modified the geolocation technique by adding lower alpha constraint which is used to determine the distance from the landmark within which the target cannot exist. Its like drawing a doughnut using fixed inner alpha and RTT dependent outer alpha. It shows improvement in case of North America (in 2 test cases error reduced from 350Km to around 200Km). He is now trying it for Europe.

He has provided results for 3 targets in each of Europe, N. America and S. Asia and compared errors with a Fixed Alpha (FA), with donuts with Alpha = 1 to define out donut radius and regional alpha to define inner donut radius.

is re-working the CBG to work in perl. this will dramatically simplify deployment.

Raja has looked at perfSONAR. He has found ~ 50 potential landmarks with lat/longs and has added to the mysql databaseWe have contacted perfSONAR to see if we can get more landmarks together with their lat/longs. There is no response, I suspect we will need to put together some code to extract the data we want.

There was interest in TULIP from Mridul Jain <mridul@yahoo-inc.com>and the Senior Architect in Yahoo! R&D Software Dev in Bangalore, India. He pointed to an interesting paper at https://www.usenix.org/legacy/event/nsdi11/tech/full_papers/Wang_Yong.pdf. He wants something to use in production, however I do not think we are ready.

On 8/27/2013, Bebo, Les and Renan met with Zakaria Maamar of Zayed university of Dubai to get monitoring hosts and landmarks. Zayed university has a campus in Dubai and one in Abu Dhabi. He Zakaria is not a networker but is happy to help out. He will discuss with the Dean and get approval of upper administration. He expects a positive response. If this fails he will direct us to some private universities. We pointed out he may be interested in Renan's work making PingER data available via Open Link data.

Working with Bangladesh to set up a monitoring site at Jahangirnagar University Dhakar. Letter of invitation has been sent. Les requested an update from Bangladesh 8/13/2013. They responded that they are having a delay getting an IP address.

Adib of UUM reposrt reported on 8/22/2013 that he has discussed the PingER project with Prof.Suhaidi “the chairman of InterNetWorks Research Lab”; he is interested and ready to support. Now, they are waiting the requirements of UUM computer centre before they can officially join Pinger team.
