Amity 

Amity team photo:

• We met with Amity 9/19/2019. The action items are below. Email was sent to Amity 10/10/2019, since there were no updates, no response. Another email was sent 10/18/2019
  • Amity will mail the update with the lat, long included. 
  • Amity will annotate the photo captured of the Amity team in the meeting. Done 10/19/2019, see above
  • SLAC also needs to know how to access the Firebase data.
    • Once that is known and the data with lat, long included and we understand the format and how to access it, Les will look at how to incorporate in a backward-compatible fashion into the current PingER.
      
  • Bebo will get hold of some Android phones and once he is given instructions on accessing the native app look at experimenting.
    • Bebo has 4 phones as of 10/16/2019
    • As of email from Amity 10/19/2019 "Drive link to the app is app" (I think it is called Firebase). 
    • Amity sent a userid and password, I think it is for the Firebase app. But it may be for accessing the Firebase data. If the latter I need some instructions  on what URL to use etc. In response to an email Naman clarified  it a little "These are the credentials which can be used to access firebase database online. See https://firebase.google.com/" 
      
    • Bebo sent email to Amity to get an update.
  • Amity will look to see if they know of any targets in Jammu Kashmir.
    • Answer appears to be no.
  • Next meeting will be in a month.
    • Amity will set up a google poll to determine the date and time 
      • The current time of 20:00 in the US and 08:30 at Amity is appropriate.
    • Amity will set up and notify the team of the meeting by Zoom. If this is a big problem Les can set up the Zoom meeting.
      
    • Amity responded 10/18/2019: We will set up a meeting within the next week.
• Bebo has an invitation to be a Keynote Speaker in the 10th International Conference, CONFLUENCE-2020 at Amity on the theme “Cloud Computing, Data Science & Engineering” to be held on 29th– 31th January, 2020. The topics are big data and the cloud. It would be by Skype. We could fit in the big data aspect. Bebo will put them in contact with Les.

Adib  (Updated 7/22/2019)

•  Adib submitted to "Socio-economic Development Indices and Their Reflection on Internet Performance in ASEAN Countries" to Journal: Engineering Science and Technology, an International Journal. They have requested a re-submission since it is over the limit of 10 pages. Adib re-submitted 7/22/2019.
  • 8/26/2019 status of this submission has changed to Revision Requested.
    
    

Saqib is undergoing his Mid  Term Probationary Review at the University. 8/26/2019 Saqib says "It is in process."

Saqib plans to continue work on PingER monitoring for remote areas, in particular in Pakistan. He will use Android PingERs. This may partially tie into the Amity project.

He will also continue his work on Blockchain and plans to attend a Blockchain workshop in Guangzhou.

The 4th  Call for Proposals for The Asi@Connect Project are now open. Saqib will submit a concept note in WP6 with Wajahat and Les as co-applicant.

• 8/25/2019: Emailed Saqib with a request for an update. Saqib replied hopefully in September.

Thailand, Charnsak 10/15/2019

MAs are down email sent to Charnsak 10/13/2019. Charnsak responded:

• I checked with the administrator.
  1. The pinger.cs.ubru.ac.th is gone. The raspberryPi is now dead. I will need to find a replacement.
  2. They just move all the server to a new location I will check with them again.
  Now I am doing a post-doc at University of Vienna also for the next 5 months.. So I can't physically access to the server this would be take sometime but I will find the way to fix it.

UNIMAS

MA is down, email sent asking for update 10/13/2019. No response by the time of this meeting.

SLAC (Updated 8/26/2019) 

The talk on PingER at the Silicon Valley Samsung HQ 7/17/2019, went well, see link below. We can use this talk for the Internet Archive.

• Long term Monitoring of the World's Networks, Les Cottrell Invited talk at the Samsung HQ in Silicon Valley, Sept 17, 2019

Les developed a tool to help in determining where targets are needed and some possibilities etc.

Also working with Umar to get the Motion metrics working again.

Iraq has had Internet problems dues to the disturbances see Iraq October 2019 

Umar 

Motion charts at https://www-iepm.slac.stanford.edu/pinger/pinger-metrics-motion-chart.html was failing it no longer displayed the contents of the charts. Umar looked at the problem and suggested a solution.  Les applied solution but did not fix in Chrome or Firefox.  See PingER Metrics Motion Chart#October2019 for details. Les finally discovered and fixed a few problems with prm.pl, create-motion-charts-page.pl, create-motion-charts-pages.pl. It is now working again but requires enabling Flash. Discussed with Umar, i=t would be possible to make the web page not use Flash, but it could be non trivial. An alternative might be to use a similar tool called Explorer (see https://www-iepm.slac.stanford.edu/pinger/explorer.html). The web is very valuable for identifying anomalous behavior which may require filtering the data.

Unfortunately he has not had any cycles to look into IPv6 vs IPv4 study. I suspect we should give up on this.

State of MAs.

Old information

Exit plan for PingER moved here 10/10/2019

• The general opinion at the July 2019 meeting was that we move to the Soft stop for PingER
  • Continue running monitors, gathering data, archiving and presenting  as long as SLAC provides storage (1TB) and pinger.slac.stanford.edu VM
    • Give up on monitors after email prompt and no resolution
    • Do not add any extra functions
  • Keep historical data publicly available as long as SLAC provides storage (1TB) and pinger.slac.stanford.edu VM

Turkey (No update 7/23/2019), moved here 10/10/2019

Jordan  moved here 10 Oct 2019 

• Baraa has just graduated from Princess Sumaya University with a Masters Degree (Major: Enterprise Systems Engineering) and is looking for Universities to continue his education (PhD.)
  • 7/24/2019 Les sent email to Baraa aksing whether and how might Baraa's future affect the MA in Jordan.
  • 7/24/2019 Baraa responded "I will have to check with my system's administrator regarding that, however I will do my best to keep the MA live.". However, Baraa responded 8/15/2019 "Since I will be leaving. The new system administrator turned it off." Les has disabled it.

UAF moved here 8/25/2019

The 4th  Call for Proposals for The Asi@Connect Project are now open. Saqib will submit a concept note in WP6 with Wajahat and Les as co-applicants

• From Les: WP6 mentions Pakistan, however, the examples are a bit of a stretch for PingER. Possibly deploying PingER MAs based on the Android in remote regions (NWFP, Gilgit, Balochistan, etc.) The difficulty will be getting collaborators in the remote regions, also probably a lot of travel to shake hands, give encouragement, assist, troubleshoot, etc. A challenge will be convincing the collaborators that they are getting something useful out of this. Maybe need to extend PingER to add some easy to use tools.  Another possibility is reviving the PingER MAs in Pakistan. Again, as Wajahat indicates, it is finding collaborators willing to install and manage the MAs. Some development may be needed to make the installation easier and maybe add remote management. Again an issue may be what do the collaborators stand to gain, and the longer-term continuation of the collaboration as people move on.
  

  WP4 talks about PerfSONAR which is monitoring. Providing training on PingER, the reverse traceroute servers might have some traction.  

   

  For both of these if one could install a mesh of MAs in Pakistan, including the reverse traceroute/ping servers (which are trivial to install on a web server, take minimal maintenance, and are much simpler than an MA) then one could address the problem of locating the lat/long of routers  by trilateration of ping response time. Note though getting the lat longs of end hosts is fairly well addressed, routers are usually identified as being located to the owner (e.g. all ESnet's routers on the US and Europe are defined as being located at Berkeley California (the HQ of ESnet)

Turkey moved here 8/9/2019

Amity moved here 7/24/2019

Android progress:

• Instructions from Aayush to load the application are at ePingER Functional prototype (for Androids only)
  • They sent a new copy of the app 4/6/2019, see ePingER Functional prototype
    • The information has been passed to Topher, who plans to install on an Android. The ball is now in our court
    • There is a discussion between Les and Aayush on how to format the raw data records, in particular with respect to the lat/long. Sent a reminder 4/18/2019.
    • We (SLAC) an email to Aayush asking how we gather the raw data from the cloud. Sent reminder 4/18/2019.
      • Aayish responded 4/18/2019: 
        Yes, we have modified the app to write the semi-colon to the file as a separator.
        However, at this point we suggest you to not make any changes to the pinger project yet. 
        
        
        Let us see and run in this parallel to what is already setup at Amity MA. This will allow us to compare the quality of results by both the systems – one at present which does not utilize the app, and the new one which requires an app for data collection.
        We send the data from the app to the firebase cloud service as JSON objects via a REST API. 
        On the cloud-server side, we intend to build a compute-service that automatically converts the json data to a txt format, for consumption by data researcher team at amity (because they are already used to running analysis on the txt files; but seem to be open to working with JSON data as well). [For the SLAC gatherer we would at least initially prefer the data to be retrieved/available in txt form. This way the changes to the gatherer are minimized and more consistent with current practice.]
        
        
        So once the team finds that the results are significant enough, then we can formally propose to include lat/long data in the Pinger gathering, archiving and analysis.
        For now, it would be best that we do not disturb the current Amity MA, and that the android project runs parallel to this."

• Topher is back, Bebo is contacting him. Bebo's thoughts were that:PingER will need a fixed name for each Android MA.  Since the Android may be mobile the IP address may be dynamic. There is a DNS name to dynamic IP address service that may be useful. Maybe there is another unique fixed identifier in an Android that could be used such as a serial number or SIM ID.
  •  If the Amity app is robust  (i.e. it does not noticeably impact the other services, power, networking, security etc) make it part of the standard Rainforest installation;
  • Topher's package knows the GPS location, so it should be available to PingER for recording.

NUST moved here 7/24/2019

• Wajahat said the letter has been received and a written response is being drafted. Is there an update?
• They (NUST) would also be interested in other collaborations with SLAC
  • Since Les is no longer an employee of SLAC but rather an emeritus this may complicate things.
  • A possibility might be in high-speed data transfer. It would need a champion from NUST, and a plan and funding to provide access to 100Gbps

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.
