Good Samaritans with Network Visibility

In a big open office 30 feet from me, a team of US Veterans speak intently on the phone to businesses large and small, issuing urgent warnings of specific cyber security threats. They call to get stubborn, confused people to take down hidden ransomware distribution sites. They call with bad news that a specific computer at the business has malware that steals login credentials. more

An Internet Infrastructure Perspective on AI Service Provision

This study analyzes the differences in domain name and IP address strategies among a number of current mainstream artificial intelligence (AI) service providers. We find that these technical choices not only reflect deployment decisions but also deep-seated corporate knowledge and capabilities in Internet infrastructure service provision, as well as brand positioning and market strategies. more

Google Claims It Fixed the Security Holes the CIA Exploited

WikiLeaks shook the internet again on March 7, 2017, by posting several thousand documents containing information about the tools the CIA allegedly used to hack, among others, Android and iOS devices. These classified files were obtained from the CIA's Center for Cyber Intelligence, although they haven't yet been verified and a CIA official declined to comment on this incident. This isn't the first time that the U.S. government agencies were accused of crossing the line and undermining online security and civil liberties, as it's been only a year since the infamous FBI-Apple encryption dispute. It's like "1984" all over again. more

Fibre Optic Technologies for the Next 50 Years

It might be hard to imagine but we were already talking about fibre to the home networks back in the 1970s and 1980s. This was in the early days of interactive TV and pay TV and fibre optics were already at that time seen as the next level of telecoms infrastructure needed for such services. The first residential fibre pilot networks were built in Berlin and Nagasaki. One of the most ambitious projects was in Columbus Ohio, but in the end they decided to continue with their HFC network. more

A Note to PhDs Transferring From Academia to the ML Industry

Congratulations. You have successfully defended your PhD dissertation, and it was a defining moment in your life. Your professorial experience and teaching assistant credentials are finally going to pay off.

Spam Peaked at 200 Billion per Day in 2008, Botnets Nexus of Criminal Activity, Says Cisco

In a 52 page security report released by Cisco, the company has confirmed what has been consistently been observed through out this year: "the Internet-based attacks are becoming increasingly sophisticated and specialized as profit-driven criminals continue to hone their approach to stealing data from businesses, employees and consumers." The 2008 edition of the report has specified the year's top security threats and offers recommendations for protecting networks against attacks that are propagating more rapidly, becoming increasingly difficult to detect, and exploiting technological and human vulnerabilities. more

Cable in China

I'm writing this piece on the plane on my way back to Vancouver after a 12-day trip in China. I've written about China before, and every time I go, I understand and appreciate this complex country and culture a little more. If you think China is "up and coming," well, you might want to go and take a look for yourself. To be honest, I think they are already here. more

More Cracks Appearing in Mobile Market

When I wrote the BuddeComm analysis on the introduction of Apple's iPhone I commented that the most significant element of this event was that it would begin to create cracks in the flawed business models of the mobile operators, who are desperately hanging on to their closed networks very much like the fixed operators were fighting tooth and nail against opening up their networks. We have seen that the fixed operators have largely lost this battle and we predict that the future of the mobile networks will be no different... more

Holding Times – A Phenomenon Happening With ISP Networks That No One Seems to Talk About

During the last year, we saw a big change in the nature of our broadband usage in that many of us are connecting to remote work or school servers, or we are connecting to long Zoom calls. We already can see that these changes have accelerated the average home usage of broadband. OpenSignal reports that the average broadband usage per home grew from 274 gigabytes per month just before the pandemic up to 462 gigabytes per month measured at the end of the first quarter of this year. more

Substantial Majority of Americans Say Local Governments Should Be Able to Build Their Own Broadband

A recent study conducted Pew Research Center in March 13-27, has found a substantial majority of the American public (70%) believes local governments should be able to build their own broadband networks if existing services in the area are either too expensive or not good enough. more

The Magical Ampersand: Hope Is Not an Integration Plan

In a software-defined and virtualised world, who will integrate the complex dynamic systems, and take responsibility for the result? It is unclear if telcos have the skills, but someone else likely does... The included image caught my eye whilst I was reviewing presentations from last October's Metro Ethernet Forum gathering in Florida on behalf of a consulting client. At first glance, it's just a marketing pseudo-Venn diagram peppered with telco tech buzzword bingo. But... more

How to Evaluate Performance of a DNS Resolver

Ten years ago everyone evaluating DNS solutions was always concerned about performance. Broadband networks were getting faster, providers were serving more users, and web pages and applications increasingly stressed the DNS. Viruses were a factor too as they could rapidly become the straw that broke the camel's back of a large ISP's DNS servers. The last thing a provider needed was a bottleneck, so DNS resolution speed became more and more visible, and performance was everything. more

Businesses Are Ready for the Metaverse

The latest technology on the horizon is the metaverse, which, stated simply, is the creation of online environments. While the primary focus of the metaverse is to create alternate realities, an application with a possible immediate big uptake is vertical presence for business meetings. Ciena, a manufacturer of fiber optic transmission equipment, recently did a survey worldwide of 15,000 business people to understand the interests and expectations of the metaverse. more
