Administration
- Johari proposes that UTM host a PingER workshop in 2014, maybe associated with another conference. Anjum will be in Malaysia then. Saqib met Hanan Jan 9th and discussed this. After the meeting Johari sent email to the Les, Hanan, Saqib, Badrul, and Adib with the issues and suggesting a skype meeting
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. What is the next step?
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.
Anjum plans to be at UM by January 28th, we all hope he has his visa by then.
Renan
Renan has contacted the admin (Vinicius) for the UFRJ PingER monitor, to see if it can be restored to a working state. Vinicius explained that hopefully around mid-February they should have the necessary hardware so they can reinstall the systems and PingER program.
- 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.
Renan
Renan has contacted the admin (Vinicius) for the UFRJ PingER monitor, to see if it can be restored to a working state. Vinicius explained that hopefully around mid-February they should have the necessary hardware so they can reinstall the systems and PingER program.
Renan started testing Virtuoso last weekend. He now has the data in an easily 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.

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.
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 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 tool to enable synchronizing Malaysian monitors is completed. It provides the ability to add, edit and delete nodes. Johari has sent less the URLs to try the URL, userid and password to Badrul, Saqib and Les to try it out. Les has not had much time so far only looked at the add form form and made some suggestions, and edit form - looks good. Johari is working on authentication for the tool. Once that is ready he will send to Badrul and SaqibRaja will 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. Is there an update? No update 2/5/2014.
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. Update?. No update 2/5/2014.
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.

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 . THis also help from SLAC, CERN, NUST, ICTP, UM and ICTP. This also helps speed things up.
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.

The annual PingER report for the International Committee on Future Accelerators (ICFA) is completed. It is available 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.
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

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.
