Routing from UNIMAS

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:

->West 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, SINGTEL
->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

Apart from Western Malaysia the routes looked very indirect (Alpha < 0.45)

The routing was initially estimated using the TEIN3 map (see below) and the PCCWGLOBAl map (for Brunei).

TEIN3 map for S.E. Asia	PCCW Global map for S.E. Asia	SACOFA map for E. Malaysia

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. Instead of the TEIN3 map we therefore used traceroutes to determine the routes.

Looking at the routes using Telecom Malaysia (58.26.240.61), it can be seen that there is a lot of variability in the RTTs reported by this node. This bears further investigation, it is possible this node is congested with considerable queuing for several of the routes.

It is interesting to see that the minimum RTT of the 3 traceroutes correlates strongly (R^2 = 0.89) with the minimum ping response for the month of December 2012, see below. It should be noted that this is not the case for UNIMAS to Malaysian hosts (R^2 = 0.23).

The ASNs are obtained using Fixed Orbits to find the relevant AS. Then using a table of AS number to name you can find out more about the AS (e.g. contacts, HQ site etc.) Another source for finding AS' is Team Cymru's whois database

The minimum RTT, average RTT, Jitter and Loss from UNIMAS to S. E. Asian countries (excluding Malaysia) for Dec 2012, are shown below (the spreadsheet is here).

Notes

ASN = Autonomous System Number
TM = Telekom Malaysia Berhad
myix.gov.my is the Malaysia Internet eXchange
The 6th hop is where the traffic is handed over to the ISP.
>n means the target host never responded, n is the last hop recorded
The min RTT is the minimum of the 3 RTTs measured at each hop.
mschosting AKA ExaBytes cloud, looks like the end host may be at cloud service provider rather than the University site. It also appears that mschosting.com name is up or sale.
The routing is very strange for www.miu.edu.my. This leads to long RTTs. I believe the traceroutes were made in mid to late December 2012. If so, they are not reflected in the UNIMAS to MIU pingtable.pl results (see below). Maybe the routes between www.miu.edu.my and pinger.uniumas.my and the host used to make the traceroute measurements are different. This bears fruther investigation.
Only 7 out of 25 Malaysian targets use MYREN as their initial ISP. how come? Is Jaring or TM part of MYREN or vice versa.
What is the relationship between MYREN, TM and Jaring (in December 2006, the Ministry of Finance of Malaysia officially took over JARING from MIMOS Berhad)

The 2010 map of MYREN seen below may help in understanding the routing. However, the UNIMAS links is here reported at 10Mbps, whereas it is 100Mbps. Also Sabah, Bintulu, Sibu don't show up in the map.

Fibre Optic cables

Sacofa (Sarawak Common Communications Facilities) owns & operates an extensive on-land fibre network within Sarawak as well as an optical fibre submarine cable system connecting Sarawak and Peninsular Malaysia. They have five Operation & Maintenance Centres in Kuching, Sibu, Bintulu, Miri & Mersing. More

There is (2011) a proposed link between Sarawak’s capital Kuching and Indonesia’s Pontianak . The Government Linked Company (GLC) of Sarcofa ,which celebrates 10 years in 2011, enjoys fibre network connectivity with Brunei and an underwater cable system to Mersing, Johor on the west coast of peninsular Malaysia.

The submarine Fiber Optic Cable which provide backbone connectivity between Labuan to Sabah, Sarawak and Peninsular Malaysia has a total bandwith of 110Gbps. Two ground satellites which facilitate as a restoration during submarine cable failure. Labuan is connected to 23 countries via an International Toll Free Services. More.

There is also a list of completed towers available.
