Video continues to be the trend to watch as devices and tablets cater to higher definition content with larger screen sizes enabling the market for longer form video on mobile, reports Sandvine in its latest Internet traffic trends report. more
OARC held a 2-day meeting in February, with presentations on various DNS topics. Here are some observations I picked up from the presentations in that meeting... In a world where every DNS name is DNSSEC-signed, and every DNS client validates all received DNS responses, we wouldn't necessarily have the problem of DNS spoofing. Even if we concede that universal use of DNSSEC is a long time off ... more
I regularly bring this issue forward, similar to the discussion in relation to the structural separation of the fixed networks, which I began just over a decade ago. What we are seeing in the mobile industry is an infrastructure and a spectrum crunch. The amount of spectrum needed to satisfy people's demand from mobile phones, tablets and soon a range of other smart devices is limitless. Mobile carriers are scrambling for spectrum... more
I can't help but think that the situation in this rather old joke applies very precisely to the current Australian efforts to compel network operators, through some contemplated regulatory instrument, to record and retain network-collected data about their customers' online activities. What I'd like to examine here the emerging picture that while networks, and network operators, make convenient targets for such surveillance efforts, the reality of today's IP network's are far more complex, and Internet networks are increasingly ignorant about what their customers do. more
As far back as 2011 we predicted that Apple would eventually enter the voice market. We indicated at that time that it was just a matter of time -- in the end it took another three years... While it didn't happen at Christmas that year the company is now ready and will use the VoLTE service to enter this market, which will make it possible to replace Telstra with any other mobile operator around the world... he telcos are not ready for this. While they should be seen as the leaders in the voice call market they are too preoccupied with protecting their traditional business and it is companies like Apple and Samsung who are now leading the charge. more
Funny how some topics seem sit on a quiet back burner for years, and then all of a sudden become matters of relatively intense attention. Over the past few weeks we've seen a number of pronouncements on the imminent exhaustion of the IP version 4 address pools. Not only have some of the Regional Internet Registries (RIRs) and some national registry bodies made public statements on the topic, we've now seen ICANN also make its pronouncement on this topic... Why the sudden uptake of interest in this topic? I suspect that a small part of this may be my fault! more
I'm writing this column in November, and that means that it is time for the traveling circus known as the Internet Governance Forum (IGF) to come down to earth, unpack its tents and sell tickets for its annual song and dance routine. The script for this year's show has been changed, and after being excluded from the main arena last year at the Athens gig, the headline act of "Critical Internet Resources" is taking a starring role this year in Rio. Some folk are even saying that it is the single most contentious issue to be scheduled at this year's IGF show. So what are "Critical Internet Resources" anyway? If folks are going to spend all this time, energy and carbon emissions traveling to Rio to talk on this topic, then wouldn't it be helpful to understand what it means in the first place? There are probably a number of ways to answer this question, so in this heavily opinionated column I'd like to look at the range of possible answers to this question. more
40%, not 92%-120%. "Data consumption right now is growing 40% a year," John Stankey of AT&T told investors and his CEO Randall Stephenson confirmed on the investor call. That's far less than the 92% predicted by Cisco's VNI model or the FCC's 120% to 2012 and 90% to 2013 figure in the "spectrum crunch" analysis. AT&T is easily a third of the U.S. mobile Internet and growing market share; there's no reason to think the result will be very different when we have data from others. more
Mid March a special plenary session of the Canadian standard committee isacc was convened in Ottawa to review the final report of the Canadian IPv6 Task Group. It was unanimously approved and the essence of its 66 pages are seven recommendations for Government, Industry, Service and Content providers, and the regulator, CRTC to proceed with diligence, even some sense of urgency. One paragraph provides an interesting new twist... more
On the afternoon of June 17 of this year, there was a widespread outage of online services. In Australia, it impacted three of the country's largest banks, the national postal service, the country's reserve bank, and one airline operator. Further afield from Australia, the outage impacted the Hong Kong Stock Exchange and some US airlines. The roll call of affected services appeared to reach some 500 serv more
Over the past several months, CITP-affiliated Ph.D. student Sarthak Grover and fellow Roya Ensafi been investigating various security and privacy vulnerabilities of Internet of Things (IoT) devices in the home network, to get a better sense of the current state of smart devices that many consumers have begun to install in their homes. To explore this question, we purchased a collection of popular IoT devices, connected them to a laboratory network at CITP, and monitored the traffic that these devices exchanged with the public Internet. more
After the botched burglary at the Watergate Apartments, every scam and scandal that hit the headlines became a 'gate' -- Irangate, Contragate, you name it. The Heartbleed bug is possibly the closest thing to Watergate that this generation of computer security had seen till the past few days -- an exploit in a component that is "just there" -- something you utterly rely on to be there and perform its duties, and give very little thought to how secure (or rather, insecure) it might be. So, fittingly, every such catastrophic bug in an ubiquitous component is now a 'bleed'. more
For people attending The Internet and Television Exchange (INTX), the redubbed Cable Show for 2015, enabling technologies are as important as always, but the transformation of business models in the video delivery industry has certainly cast a huge grip on an industry caught in the middle of a seismic change -- driven by ever-increasing broadband speeds, mobile access to content, and yes, disruptive Over-The-Top (OTT) offerings. more
On August 23 ( while I was in China) a list member Lee S. Drybrugh wrote in jest: I happened to bump into Peter Cochrane stating, "The good news is -- bandwidth is free -- and we have an infinite supply." Next by sheer accident I bumped into this in relation to Gilder, "Telecosm argues that the world is beginning to realise that bandwidth is not a scarce resource (as was once thought) but is in factinfinite." Can anyone explain this infinite bandwidth as I think I am getting ripped off by my ISP if this is true? Craig Partridge then offered what I think is a very good commentary of a difficult question where the answer depends very much on context... more
It has often been claimed that IPv6 and the Internet of Things are strongly aligned, to the extent that claims are made they are mutually reliant. An Internet of Things needs the massively expanded protocol address space that only IPv6 can provide, while IPv6 needs to identify a compelling use case to provide a substantive foundation to justify the additional expenditures associated with a widespread deployment of this new protocol that only the Internet of Things can provide. more
