At the end of a long day at Telecoms World South Asia in Dhaka, I presented some of the preliminary results of the Broadband QoSE work being done with IIT Madras. I talked about the finding that the bottleneck in Chennai and Colombo appeared to be the international segment and that the first results from the testing done in Dhaka suggested the same applied to Bangladesh, with the ISPs using satellite (versus undersea cable) were suffering very high latencies.
The CEO of a Pakistan ISP, Mr Wahaj us Siraj, said that the situation in Pakistan was very different, with plenty of capacity available on the undersea cables and low contention ratios (1:4) being used. Prices of international capacity had come down radically in recent times, he said, and now amount to only around 25 per cent of costs. I responded that we need to start testing in Pakistan soon, because this further illustrates the value of the AshokaTissa methodology, which allows the diagnosis of where problems exist which may vary from location to location. He was followed by Mr Undugodage, who was the driving force behind the introduction of ADSL to Sri Lanka, who said that they tried to give customers service equivalent to BT, using contention ratios of 1:15. This contrasted with the speaker from BSNL who blurted out that the standard contention ratio in his company was 1:20.
How is it that there can be so much variation in key parameter affecting the customer experience in three countries?
