• Membership of pinger-my in https://groups.google.com

• We are working with Dr Zaidi the new head of SEECS to investigate resources need to continue support of PingER in Pakistan. We communicated first week in August. No word since. Sent a reminder 8/1/2015. We had a rump meeting of Anjum, Hassaan and Les to discuss the way forward.

• NETAPPS2015: Adib reports "We have received some good number of submissions and the reviewing process have started already. we will have a committee meeting tomorrow at the same time of PINGER group meeting. I will update you afterward."
  

  • Four papers were submitted related to PingER August 25th

  • Anjum submitted a paper to NETAPPS2015 "Adaptive Geolocation of Internet Hosts". There is no word on acceptance of paper. The evaluation was complete by 23rd September. I think the results should be out soon. 

  • Les, Thiago, Johari, Bebo and Topher White submitted a paper on "Worldwide Internet Performance Measurements Using Lightweight Measurement Platforms". We have heard nothing on acceptance.

  • Saqib submitted a paper "PingER Malaysia-Internet Performance Measuring Project: A Case Study". This paper needs reformatting, Saqib is working on it. It also needs reviewing. Les will look at Saqib has been notified that it has been accepted. Now trying for some funding to attend the workshop.

  • Thiago and the Brazilian team submitted a paper on "Applying Data Warehousing and Big Data Techniques to Analyze Internet Performance'. Adib has kindly come up with a way in which the authors are unlikely to be able to attend, so somebody else will present. This has been accepted. Thiago is working on responding to the reviewer comments and is updating the paper.

• Bebo has potentially 9 students from Amity University near New Delhi in India interested in coming to SLAC for 3 months starting Feb until May. All expenses paid by them. They can start working remotely on project immediately. We are looking at what they can be involved in:  PingER (e.g. data warehouse project follow on with Brazil, Maris is excited about this), Android port of PingER MA with Topher, Geolocation with Anjum (Anjum is interested),  others on big data, monitoring, high performance throughput etc. However to come to SLAC they will need a US visa and they are still undergraduates so SLAC cannot sponsor them for a visa.  Bebo is contacting the students to see whether any of them already have a BS or equivalent (or higher).  Or whether any have a US visa or knows how to get one without SLAC sponsorship.

   

Geolocation Geolocation Anjum, 

• Anjum believes the TULIP Geolocation application  can be improved significantly. At least there are few ideas that we can try. For this, either a group of undergraduate students or an active masters student is required. The resultant work can easily be the thesis of masters level. Who is interested? 

  • Saqib is going to see if he has a student interested. He will contact Anjum to learn more. Update Saqib, Anjum not heardhas an MS student interested to work on Geolocation project. He requests an initial  paper on the project.

  • Johari will contact Anjum to learn more of the requirements. Update Johari/Adnan

  • See http://www.slac.stanford.edu/comp/net/tulip/. Basically TULIP uses pings to a target from landmarks at known locations and converts the minimum RTTs to estimate the distances. Then uses the distances with mulitlateration to estimate the location of the target

  • To improve TULIP one needs the right selection of landmarks, i.e. good (working landmarks) at the right locations (not too far from the target), straddling the target, and with a a reasonable estimate of the indirectness (directivity or alpha) of the path from the landmark to the target (so we can reasonably accurately estimate the distance). One also needs a reasonable density of landmarks (e.g. number of targets/100,000sq km)

  • The landmarks come from PingER and perfSONAR sites.  We have a reasonable density in the US, Pakistan and Europe. Currently Anjum is getting better than 20km accuracy for Pakistani targets

  • As the number of landmarks goes up so does the accuracy, but so does the time to make the measurements (pings). 

  • One needs to find the optimal density

  • Anjum proposes to speed up the measurements using a cluster for parallelization and also proposes to improve the adaptation of alpha based region. He regards the adaptive geolocation and parallelization as  MS projects. 

  • He is also interested in geolocation in small proximity (e.g.indoors), e.g. using cell tower signals. This is a new area of research. It is possible that the port of PingER to an Android could  be related to this. This is a PhD project

  • Anjum reports he can supervise the students on Geolocation. He will need to know when the students are ready. We can start with a joint meeting involving Les and the students. Later on, Anjum can have the meeting with students every week while Les can join if he has time.

     

Android - Bebo

• Bebo said Topher would be interested in getting a student to port PingER to an Android. Possibly one of the Chinese students. Les put out a version of the PingER MA on Github at https://github.com/iepm/ in 2013 as part of coordinating with Google( which did not get very far). It has been dormant since it was put out there. Les is not a github expert or user so is  unclear how complete it is or who can access it.   Can somebody test and if not available let Les know what to do. 

Unrest in Malaysia - Anjum, Johari, Les

...

Johari will contact Hanan to request someone to support PingER at UTM, now Saqib has left. (6/3/2015/. Hanan not replying to Johari, Johari will try another route to get a replacement for Saqib at UTM 8/12/2015). 9/2/2015 still unable to contact Hanan, Johari will try and contact the Dean.

Saqib points out a number of Malaysian routes are IPv6 which could have problems for traceroute. Saqib is checking

MYREN

 Saqib

Has a student  interested to work on Hadoop and pinger data.

Further he has a few more MS students searching for their research topics. We can also utilize them in our pinger project. They are from software engineering, database and network background.

• Thiago completed setting up the  PingER data SQL Impala warehouse running on a Nebula/Cloudera cluster using the Hadoop File System (HDFS)the PingER warehouse database at SLAC. Unfortunately . Unfortunately it is not currently accessible from outside SLAC. There have been several attempts to provide outside access, but no success yet, we need to engage the subject matter experts. Thiago is now a SLAC associate so he still has an account at SLAC. There is There was a cyber security alert on the version of java installed with Cloudera. Thiago is in New York and does not currently have WiFi. Les has replaced the cloudera version of java which should fix the vulnerability. However the new version has not been tested.

• The Raspberry Pi at SLAC is still running smoothly since June 11th.
