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"
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.
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
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), Android port of PingER MA with Topher, Geolocation with Anjum, others on big data, monitoring, high performance throughput etc.
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 heard
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. Maybe one of the Indian students could assist? Would need assistance from Anjum but Les can also assist.
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
Android - Bebo
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 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.

- Adib has managed to resolve almost all issues blocking UUM pinger from running smoothly including the problematic switch connecting our lab with the computer center, firewall setting, DNS, ..etc. Therefore, we hope not to have any connectivity problem.
- They plan to move UUM pinger to UUM computer center, I have talked to the person in charge and we just need to get the director permission to move on. This will help us to resolve the electricity problem as well as to some how guarantee stable connectivity.
- Looking at the log and data at SLAC it looks to be working since 29th September.
Fatima is currently occupied with putting together her report. Regarding her work, she has successfully implemented some MapReduce codes on the data and presently fixing some errors in the code. Requested update implemented her work (involving HDFS and MapReduce with Pinger Data) on 50MB to 200MB data sets, using a 2-node cluster, and then a 3-node cluster. The work is not completed, but she has obtained some results.
UM
Ibrahim had downloaded PingER in Zip files format, however, when he stored them in the Hadoop distributed file system (HDFS) and try to process them, the file got corrupted, so he had to extract the file, but one file zip has more than 10000 zip files with small size. So he is trying to create a mapreduce job which can accept zip format, that will save lot of his time. Currently mapreduce can only read from files like .txt, and any doc file format or database. He will have meeting with Dr. Anjum on 11 of june asking for advice and seeking of how we can work on this together. No update 9/2/2015. Anjum will contact Ibrahim.
