Administration
Anjum is at UM. ~~He He does have access to the Internet from the Lab but its a shared place and he cannot attend meetings while in the Lab. For meetings, either he shall attend it from his home, or from the common room of the building.
- Johari proposes that UTM host a PingER workshop in 2014, maybe associated with another conference.
UTM volunteered to host the workshop last year. Due to the lack of funding from UTM, UM hosted it. Hanan believes the constraint is the budget. After knowing how can we fund the workshop, then we can decide who will the host the workshop.
Adib suggested a summer school that is aimed at graduate students and researchers from different disciplines where everyone needs to be present for team presentations based on case studies/assignments given to each team. Each team will be mentored by one professional researcher (from PingER Current Member) to guide and advise. The Summer School activities will include: Keynote talk, Presentations on current projects related to Pinger that open up challenges for students to solve and address, and case studies (assignments based on the presentations) for each team of students.
- Johari talked to Adib who is interested in hosting the workshop at UUM. They believe that with Anjum in Malaysia, the main cost is for Les. Johari shared the information from the previous 2 workshops and it is believed it is good value for money. Given this, it appears the funding required is achievable. There may also be a possibility for a presentation by Les to a more public audience at the ITU Research Center, as well as the possibility of getting sponsors and requiring a registration fee for private sector people. Adib will put together a proposal and take it to the UUM Vice Chancellor.

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 writing the paper. He has completed 3 pages of 7. He hopes to have it finished soon, since the submission date is March 1st.
Renan did not not see Vinicius (the admin of the UFRJ PingER monitor). We can try to contact him via email again (maybe in the end of February?). If he doesn´t reply, Renan can try to talk to him in person again.
It would be good if somebody else was able to work with Renan to move PingER LOD forward. However we think the performance issue has to be resolved first.
UM
UM appears to be experiencing very high packet losses (>4%). We need help in understanding these. It does not look like simple congestion since the jitter and RTT is staying low. Saqib needs assistance from Badrul as part of his case study of Malaysia. Badrul
Renan started testing Virtuoso last weekend. He now has the data in an easily exchangeable format so he can transfer it from the earlier repository he was using (OWLIM) to the new one (Virtuoso). That is what he is trying to do this week: upload to the Virtuoso database. The main problem for me is that he can use only 2 hours a day to work, because of his job.
Renan is looking at submitting a paper or poster for a Big Data and Social Computing conference that will be held at Stanford: Bebo has looked at the conference and believes a posters submission would be good. Renan talked to his supervisor, Luiza and she suggested him to get in touch with another professor at UFRJ who also has experience in submitting papers for international conferences. She also has experience in big data, especially working with scientific data. This new professor, called Marta, said she can help Renan with writing and submitting for the Stanford Big Data Conference. We would need to submit a 10-pages-2-columns paper, focusing on Big Data processing (and maybe analysis), trying to also give some ‘scientific content’ approach, because this is Marta’s field of research. The due date for the paper submission is March 1st.

UM
UM appears to be experiencing very high packet losses (>4%). We need help in understanding these. It does not look like simple congestion since the jitter and RTT is staying low. Saqib needs assistance from Badrul as part of his case study of Malaysia. Badrul writes: "UM is now currently changing the new policy regarding the bandwidth and connection. They are upgrading the switch and router to a new router - mostly every weekend they shut down the network. therefore we are now having some difficulty." Saqib has identified what appear to be losses starting at a JARING router in KL. Badrul will run some mtr traceorute/pings to various sites.
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 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 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. 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.
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
No progress 2/19/2014UTM
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.

At the Connect Asia Pacific Summit in Bangkok 2 weeks ago in Januaryt 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 Hassaan 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 are now 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, pingerisl-air, pingerisl pinger.pern.edu.pk, pingerisl-qau, quest, uaf sau.seecs.edu.pk , uaf.

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
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.
