Measuring and managing subscriber bandwidth can be an easy and cost-efficient way to improve subscriber quality of experience (QoE). In a HFC cable network, bandwidth is shared among users in the same fiber-node. Even though improvements in DOCSIS technology has allowed a substantial increase of bandwidth availability per fiber-node, a few heavy users - as well as new 4K video content - can quickly kill recently-made network investments and leave subscribers with an impression that they are not receiving the quality they deserve. more
Today, we are excited to announce, in partnership with the Open Networking Foundation and Open Source SDN, the official launch of iSDX - open-source controller software for an industrial-scale Software-Defined Internet exchange point. iSDX allows independently operated networks to interconnect and exchange traffic in completely new ways. This software, which we've been developing for nearly three years, now finally operates at the scale of the world's largest IXPs and interoperates with SDN-capable hardware switches, opening up new possibilities for interdomain business relationships and traffic exchange. more
Measuring the performance of broadband networks is an important area of research, and efforts to characterize the performance of these networks continues to evolve. Measurement efforts to date have largely relied on inhome devices and are primarily designed to characterize access network performance. Yet, a user's experience also relies on factors that lie upstream of ISP access networks, which is why measuring interconnection is so important. more
The world has changed significantly since 2000, when the countries of the world adopted the United Nations Millennium Development Goals (MDGs). While strong economic growth in the developing world has helped lift millions out of poverty, global population growth, modern lifestyles and consumption are now stretching the limits of the planet's resources. During this time, technological advances in information and communication technologies (ICT) have radically transformed the way people communicate and lead their lives; now ICT can play a vital, transformative role in helping to put the world on a more sustainable path. more
"Philosophy is a battle against the bewitchment of our intelligence by means of our language." (-Ludwig Wittgenstein) The words we use to describe telecoms networks often contain hidden metaphors and meanings that lead us into wrong thinking. Here are three examples... Why misleading? The word "best" implies both benevolent and optimal intentionality: the network is going to do the "right" thing for its users, and it will maximise the "rightness" in some way. more
In the 1950s and 60s, large numbers of immigrants came to London from the Caribbean and other Commonwealth countries. They had few resources, yet needed somewhere to live. Many fell prey to exploitative landlords. These unscrupulous rentiers packed tenants into formerly swanky parts of town, which then became slums. This process even birthed a new word in British English - "Rachmanism" - to define the archetypal unethical treatment as practised by one notorious landlord. more
A British perspective on a very American process... As a new member of the the "Tech Elders", I was invited to join yesterday's hearing in Washington, DC on the reclassification of broadband Internet access services. The US Federal Communications Commission (FCC) has decreed that Internet access should switch from being lightly regulated as an 'information service' (Title I) to a more heavily regulated as 'telecommunications service' (Title II). I'd first like to say that the process and content was a credit to the rule of law in the United States. more
One of the primary purposes of global Internet Governance Forum (IGF) is to introduce a wide range of topics to newcomers and provide them with the opportunity to take back what they have learned in the hopes of establishing an understanding of the Internet Governance philosophy at the community or national level. As a first time participant at the 10th Global Internet Governance Forum (IGF 2015) that took place in Joao Pessoa Brazil, in early November of 2015, I felt the burden of being a representative from a developing country, a place where discussion of important issues is limited to a small group of individuals, often in informal settings, over coffee or in my case, green tea. more
A very Interesting meeting The Internet Governance Forum (IGF) with an ambitious theme of connecting the worlds next billion people to the Internet took place in early November 2015 in a beautiful resort city of João Pessoa in Brazil under the auspice of the United Nations. Few citizens of the world paid attention to it yet the repercussions of the policy issues discussed affect us all. more
According to data from the FttH Council, the number of homes passed with fibre in the US increased 13% in 2015, year-on-year, to 26 million. Combined with Canada and Mexico, the number of passed homes has reached 34 million. The take-up rate is excellent by international standards, at more than 50%. Commonly operators look to about 20% to 30% take-up before work can begin on new fibre infrastructure to communities. more
