Bebo reviewed and responded to Adib suggesting the second one is a better choice. Adib submitted it to the 2nd journal. He sent email 4/20/2019: "we received an unfavorable response from the information society. So sad that this paper does not get enough attention from journal editors. But I will keep trying, let's pray for the best."
Wajahat suggested a letter to the higher-ups at NUST about PingER would assist. Les worked with Wajahat to craft such a letter. It was sent to Wajahat by email 4/3/2019. It was sent by paper mail 4/4/2019 to Principal SEECS.
IPv6 host at NUST:
Wajahat has requested Hasan to install PingER on an IPv6 host at NUST, Saqib has contacted Hasan to tell him where to find and upload the code. There is not a host name for the MA yet. Hopefully, this will be available by next month's meeting.
Wajahat has 2 students, he will propose some PingER related projects to them.
Wajahat said that contacts at some sites are not very interested in PingER and wonder why there are so many pings. Thus he believes we need new sites representing the regions of Pakistan that have willing collaborators. Thus we should give up on sites such as CAE and ISRA that have not had any data to gather for a year or so. Les has since disabled these sites.
Saqib joined the University of Agriculture in Faisalabad. He plans to pursue the blockchain paper.
Charnsak is looking at a host in Champasak University, Chan Parsa province in Laos as a potential site for a PingER MA. Charnsak just got approved to make contact with the Champasak University. He expects to set up the MA in the next 4-5 months (say towards end 2018). It also depends on the partner university, and there may be a lot of paperwork. 4/9/2019 Charnsak said we need to drop this.
Need to add Umar Kalim to http://pinger.unimas.my/pinger/contact.php. From the 7/5/2018 meeting: Johari can't ssh into the server so he will go to it on Monday. He will also upload the new UNIMAS PingER website next week.
Email from Johari 4/21/2019: I am still very much interested in the project but I have to manage my time better. Will try to join the next meeting and probably get someone from my side to monitor the equipment and make use of the data collected
Umar fixed up the PingER deployment map at http://wanmon.slac.stanford.edu/wan-mon/viper/pinger-coverage-gmap.html by updating the Google map key.
Host | State | last seen | Status |

Contact (Sergey Belov) has moved on to another job, hardware is old, needs replacing and a new contact. It goes back to December 2000 when it had a 128Kbps link via KEK to the rest of the world. | April 17, 2019 | Disabled 5/8/20129. |
brunsvigia.tenet.ac.za | It was successfully moved to a VM, with same name. | April 17, 2019 | Successfully moved to a VM 5/3/2019 |
netmon.physics.carleton.ca | Unable to gather data, host is pingable and http://netmon.physics.carleton.ca/cgi-bin/ping_data.pl? responds. It appears the pinger.xml file is corrupted. Email sent 4/28/2019 | April 23, 2019 | Fixed April 29, 2019 |
maggie1.seecs.edu.pk | Unable to gather data since March 26, 2019 | March 26, 2019 |
Umar is looking at the scamper project from CAIDA, see https://www.caida.org/tools/measurement/scamper/. Les will put Umar in contact with the scamper folks (email sent 4/28/2019)
Unfortunately, for the IPv4 vs IPv6 comparison, there is insufficient data (i.e. only about targets)
Next meeting: There will be a Doodle poll, May week 20th-23rd or June 5th-6th or June 10-13 at 10 pm Pacific time; a day later 10:00 am Pakistan time; 10:30 am India time; 1:00 pm Malaysian & Guangzhou time; 2:00 pm Thailand time; 7:00 am Jordan time. 6:00am Turkey time. May conflicts with Ramadan, so Umar cannot make it then. Ramadan begins May 5th and ends June 4th. Also Bebo is away the week of May 13th.
No update to the following 3/14/2019.
Context:
Is there any statistical difference between ICMP and TCP Ping? The context here is the Internet (not data center). This is important because the network stack is different (e.g., MPI over infiniband) and latencies are significantly less.
Questions:
Why should we focus on minimum RTT instead of average RTT
Min RTT essentially reflects fixed delay, while average RTT subsumes variations and path load
Link to raw results with minRTT results:
https://drive.google.com/open?id=1ZPgljFCDFcsVUxEFA6NYMjhayoqYtMYi
Are the R plots generated using minRTT?
Averages and computed. Min RTT is available. Scripts need to be updated to use minRTT.
What is the breakdown of latency between endpoints? If there is a difference, is it because of the type or location of the source? What if the source of traffic was not SLAC? Is there a correlation with the distance between the endpoints?
Latency for an echo packet to travel up the stack and back down is about 3.75 micro seconds (see StackMap https://www.usenix.org/conference/atc16/technical-sessions/presentation/yasukata). As expected, this is negligible when considered with milli second latencies.The remaining components would be propagation and queuing delay. As we can not breakdown the two in a public network without using an active look like
To replicate use system tap. See: https://unix.stackexchange.com/questions/419449/how-can-i-determine-if-a-latency-is-due-to-a-driver-or-the-scheduler
pathchirp etc, we'll continue to consider these as a single component.
Are the differences limited to a particular region? How do we determine/understand if traffic prioritization is implemented? Test in a controlled environment to avoid variables such as traffic prioritization, queuing delay due to cross traffic. Review the time series of latencies for both ICMP and TCP ping, instead of averages?Is there a difference between IPv4 measurements vs. IPv6.
It may be that end hosts which are farther away have larger variances and thus the pronounced differences.
Bebo sent email, see below. Saqib will follow up.
Not sure whether this would be relevant for PingER work - maybe Saqib's blockchain paper? I'm not sure that there has been much discussion re: PingER security - thoughts? The submission is due May 24th

Adib moved to Karabuk University in Turkey where he is an Associate Professor.
The time difference would probably require a change in meeting time (e.g. 10:00 pm SLAC = 6:00 am Turkey)
He will discuss with the department head about installing a PingER MA there.
Regarding the paper, it has been submitted to Journal: Computer Communications
Title: Socio-economic Development Indices and Their Reflection on Internet Performance in ASEAN Countries
Corresponding Author: Adib Habbal
Co-Authors: Les Cottrell, Emmanuel Mkpojiogu, Bebo White, Suhaidi Hassan, Faisal Zulhumadi
Unfortunately, it was rejected.
Adib, Bebo and Les are looking for another journal, some possibilities include: https://webscience-journal.net/webscience,

NUST moved here 4/18/2019
Wajahat raised the topic: We also need to formulate some research problems that have the potential of appearing in some well-known places. This might help in attracting NUST students which is getting harder these days. I need your help in this regard.
Discussion . (Wajahat was this useful? Is there something else? Email sent 3/15/2019):
There is a web page at Future PingER Projects which was last updated July 2018. Topics that currently stand out include:
Applying Blockchain to PingER data, see the paper by Saqib, here.
Graphical traceroute maps. Note currently when one looks up the location of a router, it usually gives the location of the home site that is managing the routers, e.g. ESnet routers in the US and Europe are all identified as being at LBL. Using ping minimum RTTs to a router from multiple sites (e.g. the perfSONAR traceroute servers in the US, Canada, and Europe, see http://www.slac.stanford.edu/comp/net/wan-mon/viper/tulipmap.html) one can use trilateration to identify the location of the router. Earlier work on this can be found at http://www.slac.stanford.edu/comp/net/tulip/
Deploying Android/Pinger devices, understand how their low cost (cheap enough to be disposable), low power (e.g. use of solar power) and potential mobility may be used, i.e. the risks, mitigations, and benefits.
Linked Open Data applied to PingER data.
Using PingER data as a source of big data to search anomalies, trends etc.
Case studies, e.g. can one identify the impact on networking of social unrest such as the current Venezuala difficulties, or of other events such as earthquakes or Tsunamis.
I have increased the number of working Venezuelan target hosts monitored from SLAC from 3 to 8, to possibly assist in this.
Another interesting case study would be to look at the impact of hurricanes on Internet connectivity in say the Caribbean, see for example Hurricanes Irma and Maria 2017.
Compare and contrast IPv6 with IPv4 behavior, identify outliers and understand - Umar, Les, and Saqib are looking at this.
Also, see PingER Papers and Presentations for some topics that have recently resulted in papers.
Are any of these of interest?

The following are the data analysis projects:
Title (tentative): Correlation Analysis between network performance and GDP of a country using PingER data. Abstract (tentative):
This paper aims towards finding the correlation between Gross domestic product (GDP) of a country and it’s network performance (ping analysis)
using PingER data. Email ID: Naman Madan, naman.madan25@gmail.com
Title (tentative): Comparison of network performance of India and Pakistan using PingER data. Abstract (tentative):
This paper aims at comparing the network performance of India and Pakistan using the PingER network performance data of 2-3 years of both the countries and applying clustering to the year-wise data. Comparing the number of components in each cluster will help in concluding the quality of the network performance. More the number of the components, with the least average RTT, better the performance. Email ID: Vishwani Sati, vishwani.sati@gmail.com
Title (tentative): Data packets loss prediction due to environmental factors.
Abstract (tentative): Pinger data losses during certain environmental factors like – Earthquakes, heavy rainfalls, Tsunamis etc, are a major concern for the big companies, delay of few seconds will lead to huge customer breakdown. To deal with this situation, we will analyze the data losses trend with respect to the external environmental factors and will predict the data losses beforehand so that company will have upper hand if some crises stricks in future. We will analyze the Pinger data and environmental conditions attributes and will make an algorithm that will predict the losses in pinger data. Email: Gurpreet Singh, gurpreetn92@gmail.com.
