Broadband QoSE testing is generating interest. A news report on ‘Times of India’ yesterday  (April  7) suggested the site www.speedtest.net to determine connection speed. This site, like many such others available on web, lets a user to ping to a selected server to check the throughput.
At a well attended public seminar yesterday (March 18) at Institution of Engineers (Sri Lanka), LIRNEasia released its Broadband QoSE testing methodology (named ‘AshokaTissa’, after the greatest collaboration between India and Sri Lanka, the movement of Buddhism across the Palk Strait) and the preliminary test results of three of the most widely used broadband packages in Sri Lanka, SLT Office (2 Mbps / 512 kbps), SLT Home (512 kbps / 128 kbps) and Dialog (2 Mbps / 512 kbps) This was followed by the responses from SLT and Dialog Broadband. The event was jointly organised by LIRNEasia and Institution of Engineers.

The big picture on broadband QOS

Video Road Hogs Stir Fear of Internet Traffic Jam – New York Times For months there has been a rising chorus of alarm about the surging growth in the amount of data flying across the Internet. The threat, according to some industry groups, analysts and researchers, stems mainly from the increasing visual richness of online communications and entertainment — video clips and movies, social networks and multiplayer games. Moving images, far more than words or sounds, are hefty rivers of digital bits as they traverse the Internet’s pipes and gateways, requiring, in industry parlance, more bandwidth. Last year, by one estimate, the video site YouTube, owned by Google, consumed as much bandwidth as the entire Internet did in 2000. Powered by ScribeFire.
Quality of Service Experience (QoSE) of broadband was a topic that has been discussed in LIRNEasia blog for sometime and we find many readers share the view of the Australian cartoonist who portrayed information superhighway to a modern car with cart wheels – the infrastructure. LIRNEasia’s on-going QoSE benchmarking project aims to find the answer to the question, based on evidence not perceptions, whether the users actually get what has been advertised by the operators. A seminar presenting preliminary results of Broadband QoSE measures, with the participation of Professor Timothy Gonsalves of IIT Madras (who headed the team that developed the methodology) will be held in Colombo on the 18th of March. This is an open event, but prior registration is recommended. (Tel: 011 267 1160, 077 763 6821; e-mail: kapugama[at]lirne[dot]net) Here are more information about the event and broadband quality test plan for those who are interested.
Greeting people by text message (SMS) has become a general behavior. Cellular mobile networks are tolerant to processing such messages on birthdays, weddings and other personal events of their customers. But the networks get chocked when gigantic wave of messages hit the airwaves. New Year is one such event when the mobile phone networks continue processing billions of messages for quite a while. But all networks are not necessarily capable of handing the traffic of text even in the developed economies.
