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.

Ridzuan was unable to attend but sent the following status report: "My progress is that currently I am setting up the Hadoop environment to our UM servers. There have been some installation problems and will take some time to debug and testing Pinger data. We will start using Malaysia pinger data first as a starter. Will inform you the progress in our next meeting."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).

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 th data flow at SLAC and also listings of pingtable.pl and associated script.

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 out. Les has not had much time so far only looked at add form 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 Saqib.

Saqib has finished his thesis. He is applying for a Postgraduate Research assistant-ship at UTM where he plans to work on PingER. He is still waiting to hear the result. Update?
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.

Saqib has started a case study of Malaysian hosts seen from Malaysian Monitors. the 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?

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?

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.
