  • Anjum is at UM. 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 UUM are interested to host a PingER workshop at UUM in 2014, maybe associated with another conference. 
    • 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. 

Renan

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 completed writing the paper on Linked Open data access to PingER data. Bebo 7 less have reviewed and commented. It was submitted to the Stanford conference March 1st, 2014. 

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 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?

  • . However, they have two issues, one is the budget (they need to run this workshop on cost recovery basis);  second is their commitment to MYIGF which is hosted by UUM (btw 12-13 august).

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 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. 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)?

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

Adib was unable to attend 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.The PingER monitor will be up soon" 

NUST

The PingER monitor at SEECS/NUST (maggie1) is being rebuilt following a crash.

It is in beta test and needs testing by friendly users. We are looking to add a link to it from the perfSONAR home pagefriendly users. We are looking to add a link to it from the perfSONAR home page.

Raja has added 56 more perfSONAR landmarks, most of them are in North America. Currently we have 298 active landmarks (from total of 918). The Visual traceroute and TULIP have been modified to support IPv6. Also Raja has improved the laundering.

Raja is working on a paper on TULIP implementation and on the Visual traceroute that uses TULIP.

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  No update 2/18/2013.Raja has added 56 more perfSONAR landmarks, most of them are in North America.

PingER at SLAC 

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/ICFASCICPresentation_MonitoringGroupSlides20140205.pptx
