The work that we began in 2010 with UN ESCAP on improving the international backhaul capacity of Asia is continuing to move forward. The latest step is a pre-feasibility study on ASEAN connectivity conducted in early 2015 and published in 2016.
The study found that Internet traffic measurement of international paths (backbone trunk lines), undertaken in early 2015 as part of an UN ESCAP initiative showed serious problems existed in Internet traffic exchange and management within the ASEAN region. The worst result showed an international backbone trunk line download speed of 0.15Mps, latency of 230 msec and Tromboning Index (TI) value of 35. The best result was a download speed of 50.1Mps, latency of 7.5msec and TI value of 1.
The TI is the ratio of actual distance traveled by a packet divided by geographical distance. The study authors suggest that a acceptable TI should be in the range of five.
