Johari recommended a future PingER workshop later this year. Hanan at UTM has agreed to take the lead.  It will be 25-26 June at the University of Malaya.   There is a document. I  I have amended the schedule to replace Les by NUST person (Kahsif/Anjum?) for the second day technical sessions  from NUST.

...

For attendees Anjum pointed out it would be good to get 2 representatives from each of the 20 public Malaysian universities. One participant would be from the computer division (more to do with installing and maintaining), the other from Faculty (more for the research side). It would also be good to get a non MYREN University and someone from Malaysia Telecom. Bebo will provide contacts at MIMOS and Manipal.

Funding/Proposals

Johari reported that the FRGS proposal had been accepted. It is for 75K MRs (~$35K). It is for 5 people.

The Next step in funding is to go for bigger research funding, such as LRGS or eScience. 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.

There is a problem with the UNIMAS traceroute. It appears both in pinger.unimas.my and in the Raspberry. 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. Update Johari, Anjum.

Johari has set up a guest account for Anjum. Anjum logged on and reported some concerns about addresses and interfaces not matching. He does not believe it is due to the Load Balancer. The traceroute/ping server is important for the TULIP trilateration project and also understanding routing within and from Malaysia.

(1) Creative visualization of PINGer PingER data including rich interaction;

(2) Publication of PINGer data in Linked Open Data formats thereby increasing its usefulness to other researchers.  An example is RDF/XML. This could be a development project (as opposed to research) for a final year student. Anjum pointed out that converting the PingER storage mechanism is a major task based on the experience at NUST when they converted te SLAC PingER flat files to a database. On the other hand maybe one coud do the conversion on the fly in response to a request. Johari might be able to use some of the funding he received for such a development project (e.g. to enhance pingtable.pl to add this format to its download capabilities).

If these are of interest, Bebo is willing to work with students who come to SLAC and remotely with students at UNIMAS and NUST. Bebo believes that both of these areas have great potential for papers within the conference communities with which he is directly involved.

Build and install a new http://www-iepm.slac.stanford.edu/pinger/tools/pingER-2.0.2.tar.gz file with the improved version of pinger2.pl

Make PingER support IPv6. 

PingER at SLAC

The annual report to the International Committee for Future Accelerators (ICFA) Standing Committee on Inter-regional Connectivity (SCIC) has also been completed. Les has been invited to give a general colloquiam at SLAC on the Internet where it came from, challenges and how it is performing. the latter section will report some PingER case studies and measurements. 

...

Next meeting Wednesday 10  2013  April 2013 8:00pm Pacific Daylight Time, Thursday 11 April 2013 8:00am Pakistan time, Thursday 11 April 2013 11:00 am Malaysian time.

Future agenda items:

Workshop: dates, funding, other sites

UM progress

UTM progress

UNIMAS progress

IPv6 porting

Case studies: routing, performance for Malaysia and S.E. Asia. We need someone to take the lead on this for Malaysia.
