  • Instructions from Aayush to load the application are at ePingER Functional prototype (for Androids only)
    • Topher was able to make the prototype work on an android phone prior to our last call. They might have an updated app, in which case he can further test it, but he’d need to know where to get it. He offered to put it in android phone and drop it off for you at SLAC where we can also test it, in early February. 
    • Email sent to Amity 1/27/2019 asking if there is a newer version of the App. Reminder sent 4/4/2019.
  • We will use the amity anonymous FTP server to gather the data.
  • They will add the GPS coordinates (lat/long) to the MA data. This will enable looking at mobile PingER measurements.
  • We have requested (emails 3/6/2019, 3/15/2019) to know how the extra information on lat/long will be added to the records (I.e. the format of the android records) since accommodating that will require changes in the gathering/storage/analysis to be backward compatible. Thus it needs to be algorithmically simple to identify and extract the extra information. For example providing a simple separator between the old data format and the new extra lat/long data, such as a semi-colon.
    • They sent a new copy of the app 4/6/2019, see ePingER Functional prototype
      • The information has been passed to Topher, who plns to install on an Android
      • There is a discussion between Les and Aayush on how to format the raw data records, in particvular with respect to the lat/long.
      • We (SLAC) an email to Aayush asking how we gather the raw data from the cloud.
  • Topher will get us some Android phones when he gets back. 
  • Topher will get us some Android phones when he gets back. Topher is in Ecuador at the moment, he and Bebo will meet in April. 
  • At this time Topher will install the latest version of the App in the Androids
  • Les will contact Amity to see if they will have an update to the Android/Pinger by 2nd week in April. Ideally, such an update would include the location information for the MA when the measurement is made.  Email sent to Amity 3/15/2019, reminder sent 4/4/2019. Topher (the person with the Android phones) is currently in Ecuador and he and Bebo will meet early April. At that time Topher will install the latest version of the Amity Android/PingER MA App in some Android phones for testing and evaluation. Thus it would be helpful if you could aim for say Monday, April 8th, 2019 for a release of the App.
      
    As I mentioned 3/6/2019, it would be good to make the following addition to the App:
     To track measurements made by a mobile device requires one to know its location at the time of the measurement.  This information needs to be recorded together with each measurement. We need to decide how the extra information on lat/long will be added to the records (I.e. the format of the android records) since accommodating that will require changes in the existing gathering/storage/analysis to be backwards compatible. It needs to be algorithmically simple to identify and extract the extra information. For example providing a simple separator between the old data format and the new extra lat/long data, such as a semi-colon. This new location data might be appended at the end of each current measurement following the semi-colon.  

Adib (Updated 3/3/2019)

Bebo reviewed and responded to Adib suggesting the second one is a better choice. Adib will submit it to the 2nd journal.

 

NUST: (Updated 3/

  • 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?
  • Wajahat also 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.

Saqib sent email to Wajahat:

  •   It was sent by paper mail 4/4/2019 to Principal SEECS.

IPv6 host at NUST:

  • Wajhat has requested Hasan to install PingER on an IPv6 host at NUST, Saqib has contacted Hasan to tell homne where to find and upload the code
  • As discussed in the last meeting, kindly check if it is possible to get an IPv6 address in NUST for installing an IPv6 MA in PK. I will also contact PERN regarding the possibility of getting an IPv6 address. 
  • Wajahat is moving from one office to another in NUST. There are IPs but he has not been able to get to the right person. He will update if the situation changes. Email sent 3/15/2019 requesting an update.
