Mr Luigi Gambardella of ETNO responded to one of my tweets and asked me to relook at their proposal. I did (CWG-WCIT12/C-109 of 6 June 2012). On the face, it appears that they are concerned about broadband quality of service, a real problem that we have been working on since 2007. But then they go off the rails. The solution to QoS is supposedly treaty-level language mandating that “Member States shall facilitate the development of international IP interconnections providing both best effort delivery and end to end quality of service delivery,” and that “Operating Agencies shall endeavour to provide sufficient telecommunications facilities to meet requirements of and demand for international telecommunication services.
The Pacific is a tough environment for ICTs. Small populations scattered across thousands of islands over one third of the earth’s surface. More or less the opposite of South Asia. But distance does not make the need for broadband less. One requires more access when one is far away.
LIRNEasia organized a panel on Broadband Bottlenecks in Asia at the ITS India Conference. Here are the slides that were presented at the session, with apologies for the late posting. Helani Galpaya presentation on “Network bottlenecks in South Asian broadband?” Rohan Samarajiva and Abu Saeed Khan presentation on “Removing a broadband bottleneck: International connectivity” Payal Malik presentation on “How do we avoid the spectrum bottleneck?” Sriganesh Lokanathan presentation on “Teleuse@BOP4”
As attention shifts to broadband quality of service experience, more tool for understanding what’s going on are becoming available. One tool Glasnost is described in the NYT: In general, the Glasnost results suggest that telecom and cable TV operators, when they do use throttling, do so mostly to suppress bandwidth hogs and ensure a reasonable experience for all of their customers. Mr. Dischinger, now a computer engineer in Innsbruck, Austria, said throttling was much more commonly used by operators of mobile phone networks, which have much less capacity than landline grids. But with operators starting to sell superfast landline broadband service for heavy data users, such as Deutsche Telekom’s high-speed fiber-to-the-home service, the competition for bandwidth — and the need for throttling — will only increase, Mr.
A good value-added blogpost drawing from LIRNEasia research Helani Galpaya’s work: These are only a few graphs and download speeds are only one measure. What’s nice is that we can now quite confidently say Sri Lanka’s Internet and not be talking about a niche product. There are at least 280,000 fixed subscribers (including dial-up, ADSL and WiMax) and around 300,000 mobile broadband subscribers. There are also over 1 million HSPA/3G mobile users with active data use. This is all via Helani’s report btw.
Our work on broadband QoSE showed that quality deteriorates when one has to communicate with the Internet cloud. We’ve been pushing for action to reduce the prices of international backhaul from Asia, which 3-6 times the prices in Europe and N America. Another solution is to bring the data centers closer. Appears that is happening, to some extent, according to a NYT report. But China?
On May 9th and 10th, LIRNEasia presented a selection of its research on Bhutan and of potential relevance to Bhutan at events organized in Thimphu. The following news report indicates that BICMA the Bhutan regulatory body is acting on one of the findings of the diagnostic tests run on broadband connectivity in Bhutan that showed poor connectivity among Bhutan ISPs. Broadband users can now self-regulate the bandwidth provided by the operators with the help of software which will be made available for free. Bhutan InfoComm and Media Authority (BICMA), in a move to facilitate the operators give better services and to emphasis evidence-derived regulations, tied up with LIRNEasia, an ICT policy and regulation think tank. LIRNEasia is based in Sri Lanka but works in all the South Asian countries and some South East Asian countries.
When we started on measuring broadband quality back in 2007 along with our colleagues from IIT Madras, there was little else beside speedtest. Then the FCC got on the bandwagon. Now another tool. Everyone talks about being more customer-centric these days. And the incentive for focusing on customers is growing in part because customers are becoming more empowered by technology than ever – even when it comes to things like guaranteeing broadband connectivity levels.
We thought up the idea of crowdsourcing broadband QoSE, but could not make it work because the AT Tester was too complicated. In the US, they came with the idea two years later but made it work. Now someone has added value to that product. Given many governments in the region (e.g.
For a long time, we were the voice in the wilderness. But now the regulator is on the job. If the promised results materialize, we can move on to something else: “Three months ago, most operators were provided services 70% less than the speed rate advertised in the package”, TRC Director General Anusha Palpita said. The speed-up move came after the TRC carried out an evaluation of the quality of service including speeds of fixed broadband services – ADSL and WiMAX. Mr.
In a response given to the respected Hindu newspaper in connection with a story on LIRNEasia’s broadband QoSE regulation results, TRAI has indicated some changes in the broadband quality regulatory regime, starting as early as next month: S.K. Gupta, Advisor (CN & IT), TRAI, has said the definition of broadband will be modified to include only those services that offer access speeds of 512 kbps from January 1, 2011. “This will be further upgraded to 2 Mbps network speeds from January 1, 2015. A comprehensive regulation on Quality of Service is also in the pipeline.
It is nice to know that we at LIRNEasia have been ahead of the curve on Broadband QoSE, including on understanding it as more than simply download speed. Professor Gonsalves’s paper on the subject is here. The NYT today carried a story that says many of the things we have been talking about for the past two years. Tracking the speed of Internet service is becoming more and more important as everyone asks the Internet to do more than handle e-mail messages and Web pages. A few lines of text can take its time arriving, but applications sending voice calls or streaming video become unusable if there is too much delay in delivery.
Finally the TRC has woken up and started paying attention to broadband QoSE. Unfortunately, like many people and animals who are prodded awake from deep sleep, it is grumpy. It is talking about guilt and “taking action” rather than sitting down with the operators and finding a solution. “The Telecom Regulatory Commission is conducting its own investigations on mobile broadband speeds advertized by operators,” Priyantha Kariyapperuma, director general of the TRC said. “If any mobile operator is found guilty of providing slower speeds than advertized, the TRC will take action against them.
Full participation in the global Internet Economy requires electronic connectivity of considerable complexity. Today, due to a worldwide wave of liberalization and technological and business innovations in the mobile space, much of the world is electronically connected, albeit not at the levels that would fully support participation in the global Internet Economy. Yet, many millions of poor people are engaging in tasks normally associated with the Internet such as information retrieval, payments and remote computing using relatively simple mobiles. Understanding the business model that enabled impressive gains in voice connectivity as well as the beginnings of more-than-voice applications over mobiles is important not only because widespread broadband access among the poor is likely to be achieved by extending this model but because it would be the basis of coherent and efficacious policy and regulatory responses… This is an excerpt from a background report by Rohan Samarajiva, to be presented at “Policy coherence in the application of information and communication technologies for development,” a joint workshop organized by the Organisation for Economic Co-operation and Development (OECD) and the Information for Development Program (infoDev) / World Bank from 10-11 September 2009 in Paris. The report has been published in the OECD’s Development […]
Findings from LIRNEasia’s Broadband Quality of Service Experience (QoSE) study have been published in The Economic Times, India.  Broadband quality of service offered by fixed wireline operators in non-metro areas of Tamil Nadu is three times better than in the metro circles of Chennai and Bangalore, a study conducted by IIT-Madras has shown…telecommunications and computer Netwroks group of IIT-M, has conducted tests on broadband quality of service in Chennai and RoTN circles as part of a project by Asian telecom policy thinktank LIRNEasia.

If you believe something, no evidence is necessary, they say, while if you don’t know evidence is adequate. So we are not surprised if users do not agree, but that is what evidence shows. Test results from Feb 2008 and Feb 2009 round shows a clear improvement, when accessing international servers. The broken lines are for 2008, the unbroken for 2009. SLT ADSL and Dialog WiMax were tested both times.
