Is FttH Future-Proof Infrastructure?

Telecoms engineers from all of the major telecoms services and equipment companies around the world agree that FttH is the only future-proof telecommunications technology. So who should we trust - the technology experts or politicians with different agendas? If there had been a division of opinion among these experts it would have been necessary to investigate it; but if they are all in agreement it is safe to follow their advice. more

Failed Expectations: A Deep Dive Into the Internet’s 40 Years of Evolution

In a recent workshop, I attended, reflecting on the evolution of the Internet over the past 40 years, one of the takeaways for me is how we've managed to surprise ourselves in both the unanticipated successes we've encountered and in the instances of failure when technology has stubbornly resisted to be deployed despite our confident expectations to the contrary! What have we learned from these lessons about our inability to predict technology outcomes? more

More on Networks and Nationalization With Respect to Cyberwar

As a follow up to Susan Brenner's Networks and Nationalization and my comment there, I will go further in this post and talk about the "cyberwar" and "offense" aspects of her article. I think I made this point elsewhere as well... but before getting into a war, it'd be a brilliant idea to actually know that you can win. Cyberwarfare is the sort of game where you don't really need to be a huge government with the largest standing army in the world and sophisticated weaponry in order to win... more

AS Path Lengths Over Time - How Interconnected is the Internet?

One way to determine the denseness of the Internet, or its "interconnectedness", is to look at the path length between Autonomous Systems (ASes). The "shortest AS path" is a route selection rule in the Border Gateway Protocol (BGP) that means traffic from one AS will chose the path with the least number of ASes to get to the receiving AS. With IPv6 being deployed in parts of the Internet, we looked at the AS path length to see if the IPv6 portion of the Internet is more or less interconnected than the IPv4 Internet. more

Help Us Build a Sustainable European Cloud

Last month, I announced our Open Data Hub to the CircleID community, inviting anyone interested in making the digital sector more transparent to join our efforts. Today, I am excited to share summaries of our three-part series describing our vision for a sustainable European cloud. It’s a key part of our Roadmap to Sustainable Digital Infrastructure by 2030, and one that is meant to not merely challenge the dominance of the big, non-European cloud providers, but offer an entirely different paradigm that is open-source, fair, sustainable, and creates economic opportunities for all. more

Getting a Handle on IDNs

Internationalized Domain Names or IDNs are back in the news. ICANN recently released a document entitled "Proposed Final Implementation for IDN ccTLD Fast Track Process"... In a nutshell, ICANN has now offered a path toward authorizing the adoption of ccTLDs in many countries' native languages. This marks a welcome advance for millions of Internet users who do not speak English or who do not use another language covered by ASCII. But with this advance comes some concerns. more

Steering Website Traffic with Managed DNS vs. IP Anycast

I recently read an interesting post on LinkedIn Engineering's blog entitled "TCP over IP Anycast -- Pipe dream or Reality?" The authors describe a project to optimize the performance of www.linkedin.com. The web site is served from multiple web server instances located in LinkedIn's POPs all over the world. Previously LinkedIn used DNS geomapping exclusively to route its users to the best web server instance, but the post describes how they tried using BGP routing instead. more

A Report on the OECD/BEREC Workshop on Interconnection and Regulation

I presented at a OECD/BEREC workshop that was held on the 20th June in Brussels, and I'd like to share some personal impressions and opinions from this workshop. The OECD/BEREC workshop was a policy-oriented peering and exchange forum. It was not a conventional operational peering forum where the aim is to introduce potential peers to each other and facilitate peer-based interconnection of network operators, but a workshop that involved both network operators and various national and EU regulators, as well has having inputs from the OECD. more

The Net Neutrality Reversal Order: Why the FCC Will Prevail

It is now out -- all 539 pages entitled "Declaratory Ruling, Report and Order, and Order" (Reversal Order). As someone who has dealt with this subject matter at a working level over the past 40+ years, it seems clear that the FCC will readily prevail here and the protagonists need to move on. (Admittedly that is wishful thinking given the appellate revenue to be made and press blather opportunities.) The document from a Federal Administrative Law perspective is very thorough and well-crafted. more

Notes from the DNS Privacy Workshop at NDSS 2021

For many years the consuming topic in DNS circles was that of the names themselves. If you wind the clock back twenty years or so, you will find much discussion about the nature of the Internet's namespace. Why were there both generic top-level labels and two-letter country codes? If we were going to persist with these extra-territorial generic country codes in the namespace, then how many should there be? Who could or should manage them? And so on. more

Google Fiber: Technology Innovation Or Revenue Assurance?

Google's announcement of its 'Fiberhoods' throughout Kansas City is yet another example of the thought leadership and innovation being brought forward by the popular advertising company. But what does this move say about the state of Internet access in America? more

Why 5G Is in Trouble (and How to Fix It)

I have a somewhat unconventional view of 5G. I just happen to believe it is the right one. It is trapped inside a category error about the nature of packet networking, and this means it is in trouble. As context, we are seeing the present broadband Internet access model maturing and begin to reach its peak. 5G eagerly anticipates the next wave of applications. As such, 5G is attempting to both extend and transcend the present "undifferentiated data sludge" model of mobile broadband. more

Doug Madory Reports on Shutting Down the BGP Hijack Factory

A lengthy email to the NANOG mailing list last month concerning suspicious routing activities of a company called Bitcanal initiated a concerted effort to kick a bad actor off the Internet. more

Top Six IT Trends Impacting Business Networks

For decades, IT followed business. Even the development of the World Wide Web didn't move this development much beyond the four walls of corporate offices -- outside connections were essential but never informed the growth of business-critical technology. Now the growth of public clouds, enterprise-grade social networking and mobile device use in the workforce is creating a new paradigm, one where business networks are reactive to IT trends -- here are six that are set to impact companies this year. more

ARIN and Antigua & Barbuda Government to Hold Workshop on Internet Resilience

The American Registry for Internet Numbers (ARIN) is collaborating with the government of Antigua and Barbuda to strengthen the technical capacity of local network operators. ARIN is one of five registries responsible for coordinating Internet number resources worldwide. Its service area includes Canada, the United States, and several Caribbean countries. The collaboration with the Antigua and Barbuda government comes as part of a broader thrust by ARIN to support the development of the Internet across the region. more
