- Baraa is interested in monitoring other Jordanian hosts.
- There are 4 other existing targets in Jordan.

- If there are other sites in Jordan that should be monitored from say SLAC and Jordan please let me know the details and you can add them to the PingER Oracle NODEDETAILS database, so they are monitored from SLAC. If they are to be monitored from Telephoenics then they will need to be added to the <HostList>stanza of the Telephoenics pinger.xml.
- Sent email 4/18/2019: E.g. say you wanted to add alias=JO.EDU.GJU.WWW then click on the above link and you will get information like:
NODENAME: www.gju.edu.jo IPADDRESS: 87.236.233.242 SITENAME: gju.edu.jo NICKNAME: JO.EDU.GJU.WWW FULLNAME: German Jordanian University LOCATION: German Jordanian University, Amman Madaba Street, Amman, Jordan COUNTRY: Jordan CONTINENT: Middle East LATANDLONG: 31.7769 35.8 PROJECTTYPE: NOT-SET PINGSERVER: NOT-SET TRACESERVER: NOT-SET DATASERVER: NOT-SET URL: http://www.gju.edu.jo/ CONTACTS: Google COMMENTS: Add by Cottrell 5/17/2018.
Following this information you will need to edit pinger.xml to add a stanza in <HostList></HostList> of the form:
<HostList><Host> <EnableDNSCache>false</EnableDNSCache> <IP>87.236.233.242</IP> <Name>www.gju.edu.jo</Name> </Host> </HostList>
- Baraa responded 4/18/2019: "Sorry for this delay we have finished our mid term exams, I gathered a set of host and will filter them according to the given criteria by this weekend. In Jordan the weekend is Friday and Saturday."
- Baraa asked what the criteria are for choosing targets, emailed him (4/4/2019) about Finding PingER Hosts.
- Baraa provided details of 4 sites apparently in Jordan. However, only two had RTTs of > 80ms as seen from SLAC. Thus they the others are probably proxies in North America. These Unfortunately the remaining two have RTTs from Jordan of 80ms which probably means they are proxies in Europe.

- Topher is back, Bebo is contacting him him. Any progress?
Adib (Updated 3/3/2019)
- 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

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

- 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. 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 him where to find and upload the code.

- Saqib joined the University of Agriculture in Faisalabad. He plans to pursue the blockchain paper.
- 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

- 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:
- 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.
Next Meeting
Next meeting: There will be a Doodle poll, May week 13th-16th 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. Any thoughts on time of day. There does not appear to be anyone recently attending from India, Malaysia, China, and Thailand. How about 9am Pacific time, 9pm Pakistan time, 6pm Jordan time, 5pm Turkey time all on the same date.
