A Look at Why We Need Fibre-to-the-Farm

One of the discussions I am currently having with my international colleagues is about the global trend towards urbanisation and the resulting shift of political, economic and financial powers from centralised states and federal structures to mega-city or mega-urban region centres. Some of my American colleagues expressed the fear that this would further marginalise rural communication. more

How to Move Cybersecurity Forward in a More Positive Way

In 2013 I wrote a blog Telecoms as a spying tool, in which I mentioned that those who use the internet to spy indiscriminately will have to face the reality that such activities will only start a cat-and-mouse game -- the technology will always be able to stay one step ahead of those who are using the internet for criminal purposes. Since that time some very significant developments have taken place that have confirmed our prediction. more

Trust in Email Begins with Authentication

As most CAUCE supporters already know, forging 'From:' or other commonly seen email headers is trivially easy. It's one of the most frustrating oversights in the creation of Internet email technology -- though of course that's only obvious in hindsight; it was just fine for the pre-Internet networks of the late 1970s and early-mid 1980s. Since then, things have changed -- and the most interesting recent technological advancements in email have been in the realm of sender authentication, which encompasses ways to verify that the apparent sender of a message actually is the entity which sent it. more

Over 190 Internet Engineers, Pioneers, Technologists File Comments with FCC on Net Neutrality

A group of over 190 Internet engineers, pioneers, and technologists today filed joint comments with the Federal Communications Commission (FCC) explaining "Technical Flaws in the FCC's Notice of Proposed Rule-making and the Need for the Light-Touch, Bright-Line Rules from the Open Internet Order." more

IPv6 for Mobile Networks: Time to Act Now!

Mobile Network Operators (MNOs) serve the largest constituent of connected devices. There are over 4.6B GSM (and its derivatives) subscriptions today. When you add the CDMA family along with technologies with smaller footprints such as WiMax, IDEN to this list, that number tops 5B mark. On the other hand there are only (yes only!) 800M Internet hosts per ISC. Considering such a small percentage of those 5B or so devices are capable of being an Internet host and out of that percentage even a much smaller percentage is connected at a given time, one can understand the sheer potential of explosion in the number of Internet hosts as mobile devices in the next 3-5 years. more

Colloquium on Collisions: Expert Panelists to Select Papers, Award $50K First Prize

According to the Online Etymology Dictionary, the verb collide is derived from the Latin verb collidere, which means, literally, "to strike together": com- "together" + lædere "to strike, injure by striking." Combined instead with loquium, or "speaking," the com- prefix produces the Latin-derived noun colloquy: "a speaking together." So consider WPNC 14 - the upcoming namecollisions.net workshop - a colloquium on collisions: speaking together to keep name spaces from striking together. more

The Digital Decade – A Look Back

With 2019 coming to a close, we're not just saying goodbye to the past 365 days, we're also saying goodbye to an entire decade. As we bid farewell to the 2010s, we're taking this opportunity to look back and reflect on the digital decade as well as consider what the future might have in store for us all. The past ten years were a whirlwind of change, with new advances in technology exploding onto the market at a faster pace than ever before. more

What is Bring Your Own IP (BYOIP)?

An IPv4 address identifies your connection to the online world. IP addresses make it possible to host websites, manage secure communication, and engage in countless other essential, internet-related activities. Typically, when migrating to a new cloud provider, a business has only one path: lease the provider's IP addresses. But what if a business already has a block of IP addresses? more

Mind the Step(-function): Are We Really Less Secure Than We Were a Year Ago?

In January 1995, the RFC Editor published RFC 1752: "The Recommendation for the IP Next Generation Protocol"... The Internet is a security officer's nightmare -- so much openness, so easy to capture packet traffic (and/or spoof it!) and send all manner of unwanted traffic. It was built as a research network, hosted by institutes that were 1/ professionally responsible and 2/ interested in working together collegially. So, in the 19 years since the publication of that statement, have we really failed to address the stated goal? more

Why CDNs Are Critical to Future of R&E Networks, Big Data and the Internet

Netflix has announced that they are deploying their own Content Delivery Network (CDN) for delivery of their video streams to Internet Exchange Points (IXPs) around the world. More importantly they are making the hardware and software design of their CDN servers freely available. That means any network can deploy Netflix CDN boxes deep into their network to significantly reduce traffic volumes and improve performance for users. more

Five Inconvenient Facts about the Migration to 5G Wireless

An unprecedented disinformation campaign purposefully distorts what consumers and governments understand about the upcoming fifth generation of wireless broadband technology. A variety of company executives and their sponsored advocates want us to believe that the United States already has lost the race to 5G global market supremacy and that it can regain it only with the assistance of a compliant government and a gullible public. more

New Report About Internet Routing With MANRS

I find myself reading, frequently, about "interesting" exploits of IP routing. Recent history includes the redirection of Telegram traffic to Iran, Google traffic to China, and Cloudflare traffic to Nigeria -- and, per bgpstream.com, 64 events this month, 18 of them on one day. Is this expensive? You bet, both in money and in mindshare. Imagine the impact of discovering your company's name in the press. more

Network Outages Go Global

On August 30, CenturyLink experienced a major network outage that lasted for over five hours and disrupted CenturyLink customers nationwide as well as many other networks. What was unique about the outage was the scope of the disruptions as the outage affected video streaming services, game platforms, and even webcasts of European soccer. more

Cyber Security and the White House, Part 2 - Cyberwarfare

This is a follow-up to my previous post on Cybersecurity and the White House. It illustrates an actual cyberwarfare attack against Estonia in 2007 and how it can be a legitimate national security issue. Estonia is one of the most wired countries in eastern Europe. In spite of its status of being a former Soviet republic, it relies on the internet for a substantial portion of everyday life -- communications, financial transactions, news, shopping and restaurant reservations all use the Internet. Indeed, in 2000, the Estonian government declared Internet access a basic human right... more

Joint Venture Promises Broadband Benefits with Potential Risks for Latin American, Caribbean Markets

When Columbus Networks and Cable & Wireless Communications announced the formation of their new joint venture entity at International Telecoms Week 2013, it signaled an important milestone for the telecommunications sector in Latin American and the Caribbean. The development comes at a time when the region's appetite for bandwidth is rapidly rising. The market for wholesale broadband capacity is experiencing solid growth and shows no sign of slowing anytime soon. more
