Following the last meeting Les will made available via FTP examples of PingER data. There are two types:
...
"I have come up with initial proposed solution model. This model consists of several parts. The upper parts of the Figure below shows the data source, in which PingER data will be convert into RDF format. Then the data pre-processor will take care of converting RDF/XML into N-triples serialization formats using N-triples convertor module. This N-triple file of an RDF graph will be as an input and stores the triples in storage as a key value pair using MapReduce jobs"
Les fowarded forwarded by email the information from Ibrahim to Renan following the meeting

Saqib has talked to MYREN they say the routers at hops 5 and 6 in the traceroute from UM to UNIMAS are both at UM and the long delay between them is due to congestion. I am Les is skeptical since hops 6-12 have similar RTT and 12 is near Kuching. I suggest Saqib Les suggested Saqib run mtr for a day or more from UM to UNIMAS see if there is any day night variation in RTT. If min RTT gets down to <2 ms, then the MYREN guy is right. If it is ~ 50ms and persists for several days then it really does not look like congestion (which should vary day night as the number of users changes). In that case then it really appears hop 6 is physically close to hop 12 since they have the same min RTT. Taken together with the email from UM I would be very suspicious of the MYREN statement.
Saqib met with MYREN who have made many topology changes. Saqib will also incorporate these into the Malaysian case study. He is seeing anomalously long delays between mainland Malaysia and Sarawak. It does not appear to be due to congestion. We need to understand the routing and which undersea cables are being used. Saqib will send more details after the meeting. He will also contact MYREN.
Is there an update?
Saqib Saqib's proposal has submitted his proposal to FRGS. He received a requested revision. Saqib has sent a copy to Anum and Les. Anjum is going to help edit the proposal.
