Renan realized that testing on Virtuoso is going to take longer than he thought because of the big number of triples. He did not have enough time to continue his tests.
Renan is still writing the paper, though. Unfortunately, he is slow because of his job... He . He has completed 3 pages of 7. He hopes to have it finished soon, since the submission date is March 1st.
...
Badrul plans for his undergraduate student (Abdulrahim Haroun Ali) to have a draft paper on anomalies in PingER measurements to share for review by the end of semester (January). Update?
Ridzuan just solved the first part of the installation (Ubuntu servers) and is now starting to configure Apache Hadoop nodes for Pinger data storage. is still in the configuration process for communication between the Hadoop nodes. Need some troubleshooting at the moment.
Ibrahim Ibrahim Abaker is planning to work on topic initially entitled " leveraging pingER big data with a modified pingtable for event-correlation and clustering", The purpose of this project is to make Pinger more efficient and more scalable to retrieve and analysis pingER raw data. consequently Consequently it may improve pinger data store. He is planning to use key-value store model with high expandability and shorter query response time. The benefit of such project will help in the design of real time analysis and distributed pinger data across multiple servers for analysis. Les has sent him a pointer to documentation on the data flow at SLAC and also listings of pingtable.pl and associated script.
UNIMAS
The Raspberry Pi is at the data centre, but due to miscommunication, the public ip which was previously assigned to the rasp pi unit has been assigned to another server. So now Johari has to wait for the ip to be reassigned back to rasp pi unit and give new ip to the other server. They suggested a new ip for the rasp pi unit but Johari wanted to have the old one so that we do not have to update the record at slac for the archival process, etc
The tool to enable synchronizing Malaysian monitors is completed. It provides the ability to add, edit and delete nodes. Raja has tested and after a mod was made to replace a private IP address it is working well. Badrul and Saqib need to try it out.
The traceroute server at http://pinger2.unimas.my/cgi-bin/traceroute.pl has the same problem as before. They know (sort of) the problem but haven't got the chance to rectify it (mapping NAT address, needs to be added). There is no progress 12/4/2013, 1/8/2013, 1.22.2014, 2/5/2014. Now that the historical traceroutes are working for UM (see below) there is an extra incentive to get the reverse traceroute working at UTM and UNIMAS
Johari has a research student who finalized a proposal in order to officially apply for his masters. He will start in February. He is currently working on threshold/anomaly detection, and will extend to correlating performance over multiple routes. He will share the proposal with Les and others in the next 2 weeks to get reviews.
UTM
Saqib received an email regarding the successful selection of research assistant-ship at UTM. However, he is waiting for an official offer letter from research management center.
Saqib is working with the IT department in UTM to solve the problems of delays in traceroute. They have a new ISP. Now the pinger server is working with single static IP (161.139.68.188) both for intranet and internet. Previous internet IP 161.139.146.158 is removed. Again given the new historical traceroute facility (see below), it is important to get this working.
- No load balancing is involved as UTM is working with single ISP.
- Still the problem of the delay in traceroute is not solved. It appears to be due to the DNS lookup delay.
Saqib has started a case study of Malaysian hosts seen from Malaysian Monitors. The case study is identifying the need for the Malaysian monitors to collect traceroutes to their target hosts daily. SLAC has a script to facilitate this, for routes seen from SLAC, that could be adapted for other sites. The latest copy of the word file was shared with Badrul and Johari. No update 2/5/2014.
UUM
...
He is currently writing a proposal, which will contain a problem statement, objectives, scope and the approach to tackle the problem. He asked: how much PingER data is captured and stored so far (~ 1TByte)? Is there a published paper (see http://www-iepm.slac.stanford.edu/paperwork/ieee/ieee.pdf)?
UNIMAS
No progress 2/19/2014.

NUST
At the Connect Asia Pacific Summit in Bangkok 2 weeks ago and seeing the project "Mapping the pan Asia Pacific information Superhighway and closing gaps in infrastructure connectivity" Shahryar found that very much related to the work in the PingER project. So Shahryar sent email to a UN agency for a possible collaboration with them on PingER project. He has heard nothing so he will write a detailed proposal and then should contact them again. No update 2/5/2014.
Hassan reports that they have established contact with people in Bahawalpur. The contact person forwarded the request to higher authorities for approval of PingER deployment.
The contact at Sahiwal did the installation of PingER node by himself but data is not being collected, so we are in contact to resolve the issue. Kashif believes he missed some Linux updates. Today is holiday here and he will do the trouble shooting on 6th Feb.
We were gathering data from Pingerisl-air (this is continuing to work), and Quest (stopped working Feb 13)
We are still unable to gather data from airuniversity, buitms, cae, duhs, pinger.pern.edu.pk, pingerisl-qau, sau.seecs.edu.pk , uaf.
Monitors Status
Airuniversity New installation will be install in a week
Buitms Problem in hardware, they are trying to fix it. System Replacement Required
Cae Problem with IP, they are trying to resolve it
Duhs They are purchasing new servers in two week time
pinger.pern.edu.pk since Jan 13, System not booting
Pingerisl-qau Contact person is still on leave. He is now busy in other pending works.
sau.seecs.edu.pk for all of January. Contact person is not attending
Uaf Problem in system, visit approval for Faisalabad University in progress. Approved for 12th Feb
TULIP - Raja
We have sent a reminder email to Yahoo giving them an update on TULIP and how it might be extended to meet their needs. They have responded, they appear to be interested. We are trying to interest them in providing landmarks.
Raja uses the options feature of traceroute.pl to reduce the time for the PingER/perfSONAR landmarks to make the pings by a factor of 5. Given this we probably need to review the timeouts. Also we are now using caching and nightlty we populate the caches by a cronjob tracerouting to the PingER targets from SLAC, CERN, NUST, ICTP, UM and ICTP. This also helps speed things up. We added wildcards and comments to the caching.
Raja has used TULIP's geolocation to provide a Visual traceroute. It can be accessed via http://www.slac.stanford.edu/comp/net/tulip/. It also shows the route as seen GeoIPTools and other methods. Several features have been added to speed it up: the caching, and not bothering with regions where there are insufficient landmarks etc.
PingER at SLAC
UUM
Dec 4, 2013: The director of computer centre has agreed to support this collaboration and already appointed one staff to be with us during the configuration. Next step, Adib needs to discuss with Prof. Suhaidi to dedicate one PC OR get support from Badrul grant to buy one PC for this purpose or have a bake sale and buy a Raspberry Pi. Adib will do his best to setup PingER monitoring host at UUM before the end of this year. Adib was not on the meeting. He provided an update by email: "Still waiting to get PC. But they promise to provide one very soon. it is totally beyond my control." Regarding the meeting, Adib will attend the upcoming meetings once UUM pinger host is up. No update 2/5/2014.

Kashif reports (2/19/2014): "We are in a process of shifting us along with equipment to another lab from a week. Due to this transition process and new installations, Joun could not contact further to the contact persons about the down PingER Nodes. This shifting process will complete on coming Friday and after that i will be able to update you about the task on NUST part."
TULIP - Raja
Please try out http://www-wanmon.slac.stanford.edu/cgi-wrap/reflector.cgi?function=vtrace It is a visual traceroute. It uses TULIP to locate the routers. It is in beta test and needs testing by friendly users. We are looking to add a link to it from the perfSONAR home page.
We have sent a reminder email to Yahoo giving them an update on TULIP and how it might be extended to meet their needs. They have responded, they appear to be interested. We are trying to interest them in providing landmarks. No update 2/18/2013.
Raja has added 56 more perfSONAR landmarks, most of them are in North America. Currently we have 298 active landmarks (from total of 918).
PingER at SLAC
The annual PingER report for the International Committee on Future Accelerators (ICFA) is completed. It is available at We put together a slide presentation to ICFA in Geneva, to be given by Harvey Newman. It is at: http://www.slac.stanford.edu/xorg/icfa/icfa-net-paper-jan14/report-jan14.docx. We are working on a slide presentation to ICFA in Geneva, to be given by Harvey Newman.ICFASCICPresentation_MonitoringGroupSlides20140205.pptx
Raja has also re-written the historical traceroute facility that takes nightly traceroutes and allows one to retrieve and compare them. He then extended it to use the reverse traceroute facility to provide histories for NUST, CERN, UM as well as SLAC. When the UNIMAS and UTM traceroutes work, we can include them. See for example http://www-wanmon.slac.stanford.edu/cgi-wrap/traceroutearchive.cgi

Anjum suggested Saqib, Badrul and Johari put together a paper on user experiences with using the Internet in Malaysia as seen from Malaysian universities. In particular round trip time, losses, jitter, reliability, routing/peering, in particular anomalies, and the impact on VoIP, throughput etc. It would be good to engage someone from MYREN.
