Best Practices in the Global Internet

In an increasingly global environment, the Internet infrastructure industry faces a diverse set of serious issues that we as an industry need to address together. To look at these concerns, an area of focus for the Internet Infrastructure Coalition (i2Coalition) has been best practices for our industry. Our approach to developing best practices encapsulates three areas, always with the goal of striking the right balance between security, safety and privacy: working with experts and industry professionals; identifying like-minded partners; and fostering the growth of the Internet economy. more

Complexity and Crashes

It's a familiar story by now: on the 8th of August, 2016, Delta lost power to its Atlanta data center, causing the entire data center to fail. Thousands of flights were cancelled, many more delayed, and tens of thousands of travellers stranded. What's so unusual about this event is in the larger scheme of network engineering, it's not that unusual. If I think back to my time on the Escalation Team at a large vendor, I can think of hundreds of situations like this. And among all those events, there is one point in common: it takes longer to boot the system than it does to fix the initial problem. 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

Networks Are Not Cars Nor Cell Phones

The network engineering world has long emphasized the longevity of the hardware we buy; I have sat through many vendor presentations where the salesman says "this feature set makes our product future proof! ... Over at the Networking Nerd, Tom has an article posted supporting this view of networking equipment, entitled Network Longevity: Think Car, not iPhone. It seems, to me, that these concepts of longevity have the entire situation precisely backward. more

The Future of Networking (In One Slide)

I recently ran a workshop in Asia and to guide attendees through the content; I put together an overview slide which you might also find of interest and use. It is a description of the quality attenuation framework, originally developed and defined by Predictable Network Solutions Ltd, and documented and extended by myself and colleagues at Just Right Networks Ltd. 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

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

Watch Live Tonight – 2019 Internet Hall of Fame Ceremony

Tonight (27 Sep 2019) you can watch the 2019 Internet Hall of Fame induction ceremony streaming live out of Costa Rica. Eleven individuals from six countries will be inducted into the Internet Hall of Fame (IHOF) today. The 2019 class of inductees have expanded the Internet's reach into new regions and communities, helped foster a greater understanding of the way the Internet works, and enhanced security to increase user trust in the network. more

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

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

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
