Introduction
We used pingtable.pl to look at the "Directivity (Alpha)" of connections from UNIMAS to other hosts in S.E. Asia.
We observed from UNIMAS:
->W MY A~0.45
->PH via JP A~0.22
->ID via HK A~0.17, traceroute via Telecom Malaysia
->TH via SG A~0.3, traceroute via Telecom Malaysia
->BR via KL-HK A~0.07, traceroute via Telecom Malaysia and PCCW Global (HK)
->KH via HK-VN A~0.16
->VN, traceroute via Telecom Malaysia and PCCW Global (HK)
->SG A~0.23, traceroute via MYREN and TEIN3
The routing was initially estimated using the TEIN3 map (see below) and the PCCWGLOBAl map (for Brunei). However according to the traceroutes only the route to Singapore actually uses TEIN3. This is also the only route to use MYREN. All the other routes use Telecom Malaysia
