Anjum, Kashif, Johari, Abdullah, Badrul, Hanan, Saqib, Les; Raja, Umar and Bebo were unable to attend and sent their apologies.

The workshop brochure is here. The talks from Kashif and Les are linked to here. Johari is preparing a report on the workshop. Johari recommended a future PingEr workshop later this year. This time it would be in Peninsular Malaysia hosted at either UTM or UM. Tis This should be a topic for the next meeting, i.e. who should host it, dates etc.
Funding
There are rough minutes of a discussion on funding held between SEECS, UNIMAS and SLACfollowing SLAC following the workshop. The action items were:
...
Johari has a draft, it needs polishing. He will email it to the team on Monday 14th January. He proposes submitting for a FRGS grant. It will be a 2 year project with a maximum of 150K RM. It is for a single MS student. Both UTM and UM expressed enthusiasm to join. Hanan wil be the UTM contact, Abdullah will be the UM contact. The objective will be to set up a PingER monitoring site infrastructure in Malaysia. This will be used to gather end-to-end active monitoring data both within Malaysia, to S. E. Asia and to the rest of the world. This data will be mined to understand the status of Internet connectivity, set baselines, identify problem areas, make recommendations etc.
At a later stage the infrastructure and data can be used for research in: anomaly detection; correlation of performance across multiple routes; and for GeoLocation. Johari would like to see UM and UTM, which are research universities, strongly engaged in the next round of research proposals. Anjum mentioned a paper on Evaluation of IP Geolocation Algorithms on PingER and PlanetLab Infrastructures , by Fida Gilani et. al. submitted to IEEE INFOCOM 2011UNIMAS. THis could be updated with new data and maybe submitted to a different venue. Anjum will forward 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.
UNIMAS

There is a problem with the UNIMAS traceroute. It appears pinger.unimas.my is behind a NAT that is not passing the traceroute UDP probes. Other hosts at UNIMAS are not seeing the problem, so Johari believes it may have to do with the IPTABLES in pinger.unimas.my. Traceroute using the -I option (send the probes using ICMP rather than UDP) seems to work (but needs root access). Thus it would appear not to be in the return (ICMP "time exceeded") response. The probes (when not using the -I option are UDP packets using sequentially ports 33434 - 33465 (for up to 30 hops). It is possible that ports > some number may be blocked. Johari Johari will set up a guest account for Anjum who will logon and look around and see if he can assist. The traceroute/ping server is important for the TULIP trilateration project.
Les has started a report on traceroutes from UNIMAS. We have traceroutes from UNIMAS: to Peninsular Malaysia; to a host in the Philippines. It is interesting that it appears UNIMAS does not use TEIN3 or MYREN apart from the route to Singapore. All the other routes Les measured go via the commercial ISP Telecom Malaysia. Also for the Telecom Malaysia routes it appears there maybe some congestion at 58.26.240.61 since the RTTs vary a lot. This is not conclusive since routers give high priority (do it in hardware) to routing packets and lower priority to traceroute packets. Further work awaits traceroue.pl working at UNIMAS and UTM and possibly UM
Telekom Malaysia, tested the 500 MBps line from 3rd to 9th of Dec. No major effect was seen (about a 10-14% improvement in RTT). It was not possible to turn off the traffic shaping. As far as I know no iperf TCP performance memory to memory or Speedtest or NDT measurements were made.
Johari suggested and agreed to set up a web landing site for the Malaysian collaboration. It will contain the objectives, coordinates for the team members etc. The SEECS and SLAC PingER sites will have links to it. It would also be good to have an archived email list for communications.
UTM
Anjum visited University of Technology Malaysia (UTM) on the way back from UNIMAS to Pakistan. He met with Dr. Hanan. During Anjum's last visit to UTM he had asked Dr. Hanan to deploy PingER monitoring node at UTM. Dr Hanan has now appointed Saqib (PhD student at UTM) to complete the deployment. Dr. Hanan sent a request two to three days ago to the UTM network team for a live IP address. He does not expect a problem. Dr. Hanan has also agreed to explore the possibility of having a PhD student work on the data auto-correlation part for link error detections once the monitoring node is set up. Meanwhile Saquib has successfully installed the traceroute.pl and pinger2.pl software on a private IP address host at UTM.
