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.
UNIMAS
The IPDV jitter looks high for UNIMAS seen from SLAC in Nov & Dec. Saqib needs help from Johari to try and understand this. Could it be due to students? Johari does not recall any particular reason for the high jitter.
The UNIMAS monitor was down over the new year. The problem was that the pinger2.pl file was moved. It was restored, however it was running an older version. Johari has fixed this. He has also loaded the latest version of ping-data.pl that has better diagnostics.

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.
The traceroute server at http://pinger2.unimas.my/cgi-bin/traceroute.pl has the same problem as before. They know (sort of) the problem but haven't got the chance to rectify it (mapping NAT address, needs to be added). There is no progress 12/4/2013, 1/8/2013, 1.22.2014.
