Turkey (No update 7/23/2019)

Amity (Updated 7/24/2019)

Amity team photo:

• Bebo contacted Amity to discuss futures, also see the recent history at the bottom under Old Information. Also the MA is very unreliable.
  
• Amity responded 7/31/2019: with:

  • A document containing brief information about work completed  (for both android and data analysis team).

  • Confluence papers are online and the details are in PingerAmityStatus_pdf

  • The Resume of our current team members is also submitted .

  • We will fix a date around the first week of August. We will confirm the same soon. 

• Following discussions with Bebo after the meeting, we agreed to let Amity take the leading role and will wait to hear from them.

• Les also contacted Amity to see if they can provide any input for target sites in Jammu Kashmir so we can monitor them and look for any correlations in Internet performance following the revocation of JK's special status by India. See Jammu Kashmir 2019.

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.

Les succeded in renewing Saqib's account at SLAC.

Thailand, Charnsak (No update 7/23/2019)

UNIMAS

MA is down, email sent asking for update 8/25/2018.

SLAC (Updated 8/26/2019) 

Les has arranged to give an invited talk on PingER and monitoring the Internet at the Silicon Valley Samsung HQ 7/17/2019.

Les will be in Beijing China from September 2nd thru 10th,  giving an invited 20 minute talk entitled "First international computer network connection between China and US". at the Symposium on 30 years of BES Physics to be held at the Institute of High Energy Physics, Beijing, P. R. China, from September 5 to 6, 2019. The web page for the symposium is   https://indico.ihep.ac.cn/event/9761/.

Les and Bebo visited the Internet Archive (IA, see https://archive.org/) and initiated a discussion on archiving PingER data (i.e. a mirror for SLAC) at the IA and also giving a talk on PingER at the IA. 

• The IA responded with information on using an IA Python library to archive the data at the IA. Les responded with interest but lack of resources until mid-September at the earliest.  Also maybe after giving a talk at IA (see below) there might be interest in collaborating form some of the attendees.
• The IA also responded pointing to a form to fill out for a request to give a talk at the IA.
  • Les filled out the form.
  • Les sent an email to the IA to make sure they had received the form and asking if anything else is required.

Looked at ping access (via Avg-RTT, Min-RTT and loss) to up to 10 Hong Kong hosts (mainly Universities) in last 120 days. Unable to see any direct correlation between days of civil demonstrations and ping metrics.

Trying to find some Kashmir hosts.  Have 2 potentials. Will share the information with Wajahat and Amity. See Jammu Kashmir 2019.

All hosts in Djibouti stopped responding, found another host via Wikipedia.

State of MAs.

Umar compare ICMP and TCP Ping

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

Next meeting:  There will be a Doodle poll, for September 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.  

Old information

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.
