Workshop
- The web page for the PingER Workshop in UM is available from http://pinger.unimas.my/pinger/workshop.php
- Can we add a list of attendees, their institute and email address? Johari has sked UM for this.
- People from UTM, UM, UNIMAS and UUM attended.
- Mimos and MyREN were invited but did not respond.
- Follow up
- Working with Bangladesh to set up a monitoring site at Jahangirnagar University Dhakar. Letter of invitation has been sent.
- Working with Adib to get monitoring host at UUM. Adib is travelling.
- Hossein Javedani of UTM is interested in anomalous event detection with PingER data. Information on this is available at https://confluence.slac.stanford.edu/display/IEPM/Event+Detection. We have sent him a couple of papers and how to access the PingER data. Hossein and Badrul have been put in contact.
- MD NOR RIDZUAN BIN DAUD of UM is interested in analytics with Big Data for PingER. Have pointed him to Renan's work. Renan needs to send documentation.
- Do we need to add anyone to the weekly meetings?
Funding/Proposals
Johari reported that the FRGS proposal had been accepted. It is for 75K MRs (~$35K). It is for 5 people. It became available in June. Progress Johari.
Badrul put together a proposal for an outreach program. It is similar to Johari's FRGS proposal. It will be used to expand the monitoring hosts. Badrul is looking is collaborating with UUM. Verbally they have approved the grant, He still waits for the offer letter from them.
The Next step in funding is to go for bigger research funding, such as LRGS or eScience. Such proposals must lead to publications in high quality journals. They will need an infrastructure such as the one we are building. We can use the upcoming workshop (1 specific session) to brainstorm and come up with such proposal. We need to do some groundwork before that as well. Johari will take the lead in putting together 1/2 page descriptions of the potential research projects.
- Need to identify a few key areas of research related to PingER Malaysia Initiative and this can be shared/publicized through the website. These might include using the infrastructure and data for: anomaly detection; correlation of performance across multiple routes; and for GeoLocation. Future projects as Les listed in Confluence here https://confluence.slac.stanford.edu/display/IEPM/Future+Projects can also be a good start and also Bebo's suggestion.
- Need to synchronize and share research proposals so as not to duplicate research works. how to share? Maybe not through the website, or maybe can create a member only section of the website to share sensitive data such as research proposal?
Anjum mentioned a paper on Evaluation of IP Geolocation Algorithms on PingER and PlanetLab Infrastructures, by Fida Gilani et. al. submitted to IEEE INFOCOM 2011. This could be updated with new data and maybe submitted to a different venue. Anjum forwarded a copy of the paper to Johari, Abdullah and Hanan with copies to the team. The idea is to see whether there is interest at UTM, UM or UNIMAS.
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.
UNIMAS
Johari has another Raspberry Pie. He has installed the PingER monitoring. He is seeing the same traceroute behavior. he is lookingh for a DNS for the host. He is trying to create a custom built Ubuntu/PingER installation. Based on what he learnt from giving the tutorial on installing PingER he is improving the process. the idea is taht if we could get a corporate sponsor then we could send preconfigured units to new monitoring sites to simplify things.
UTM
Saqib is starting to look at Pingtable.pl anomalies as a start in a case study for Malaysia and S.E Asia. In particular hosts which are unreliable, hosts with large (>1) values of Directivity, host with large RTTs, hosts with large unreachability or losses etc. Saqib has been busy with thesis so no progress, will be available June 12th on. Les had some questions on the locations of some sites that have impossible values of Directivity. One has been Disabled, any word on Allianze? What about QIUP? Saqib will investigate. Update. Saqib was not at the meeting so there is no update.
Hossein Javedani of UTM was interested in anomaly detection in PingER data. We have sent him a couple of papers and how to access the PingER data.
UM
Badrul has been looking at anomalies in ping measurements. Les sent some pointers to previous work on anomaly detection in time series. There should be a presentation at the workshop on the plans and progress. There is no progress, the student is on vacation, expected to return next August.
Abdullah and Badrul will be meeting next week to look at data mining for PhD studies.
Ridzuan Bin Daud of UM is interested in Big data Analytics for PingER, see https://confluence.slac.stanford.edu/display/IEPM/PingER+Big+Data+Analytics+proposal;?
NUST
Raja has sent mail to the US embassy enquiring about the visa. He is still waiting. He sent email Anjum to see if Arshad can move things forward. He will need a new DS-2019 by the time the visa is issued.
TULIP - Raja
Raja has modified the geolocation technique by adding lower alpha constraint which is used to determine the distance from the landmark within which the target cannot exist. Its like drawing a doughnut using fixed inner alpha and RTT dependent outer alpha. It shows improvement in case of North America (in 2 test cases error reduced from 350Km to around 200Km). He is now trying it for Europe.
He has provided results for 3 targets in each of o Europe, N. America and S. Asia and compared errors with a Fixed Alpha (FA), with donuts with Alpha = 1 to define out donut radius and regional alpha to define inner donut radius.
PingER at SLAC
Johari has added Renan to http://pinger.unimas.my/pinger/contact.php (http://pinger.unimas.my/pinger/contact.php*).
He also needs to be added to the pinger.my emailing list.
Les extended dbprac.pl (accessed via the ? in pingtable.pl) to provide information on who monitors whom. This was needed for Renan's to load data from PingER into Open Link Data format.
Renan is working on providing standardized semantic (using Linked Open Data principles) access to PingER analyzed data for various time slices and metrics. This is a web standard and opens up te PingER data to a huge community for data mining, analytics/correlation analysis, mashups etc. For example can we use Geonames (see http://www.geonames.org/) given the location of a University site compare with TULIP's estimates on a Google map, add in university funding, students/faculty ratio and PingER RTT. Renan is close to finishing up the first creation of the RDF repository. Following this updates will need to be automated. Renan needs to set up a confluence wiki site. There appears to be interest at UM.
Potential projects
