Let’s Face Facts: We Need a New Industrial Internet

The Internet is a great success and an abject failure. We need a new and better one. Let me explain why. We are about to enter an era when online services are about to become embedded into pretty much every activity in life. We will become extremely dependent on the safe and secure functioning of the underlying infrastructure. Whole new industries are waiting to be born as intelligent machines, widespread robotics, and miniaturized sensors are everywhere. more

Commercial Incentives Behind IPv6 Deployment

The Best Practice Forum (BPF) on IPv6 at the Internet Governance Forum (IGF) explored what economic and commercial incentives drive providers, companies and organizations to deploy IPv6 on their networks and for their services. The BPF collected case studies, held open discussions online and at the 2016 IGF meeting, and produced a comprehensive output report. This article gives a high-level overview. more

Mitigating DDoS

Your first line of defense to any DDoS, at least on the network side, should be to disperse the traffic across as many resources as you can. Basic math implies that if you have fifteen entry points, and each entry point is capable of supporting 10g of traffic, then you should be able to simply absorb a 100g DDoS attack while still leaving 50g of overhead for real traffic... Dispersing a DDoS in this way may impact performance -- but taking bandwidth and resources down is almost always the wrong way to react to a DDoS attack. But what if you cannot, for some reason, disperse the attack? more

Help Us Answer: What Will the Internet Look Like in 10 Years?

What will the Internet look like in the next seven to 10 years? How will things like marketplace consolidation, changes to regulation, increases in cybercrime or the widespread deployment of the Internet of Things impact the Internet, its users and society? At the Internet Society, we are always thinking about what's next for the Internet. And now we want your help! more

If Slate Comes in Standard Sizes, Why Not Broadband?

Last week I was at the National Slate Museum in Wales watching slate being split apart. On the wall were sample pieces of all the standard sizes. These have cute names like "princess". For each size, there were three standard qualities: the thinnest are the highest quality (at 5mm in thickness), and the thickest have the lowest quality (those of 13mm or more). Obviously, a lighter slate costs less to transport and lets you roof a wider span and with less supporting wood, hence is worth more. more

Italy’s Earthquake Rescuers Ask Locals to Unlock Their Wi-fi to Assit in Search and Rescue

The Italian Red Cross says residents' home networks can assist with communications during the search for survivors following Wednesday's 6.2 magnitude earthquake which struck central Italy killing over 240 people. more

IoT Developments: NIST Issues Tech Guidance while NTIA Seeks Broad Input, Global Efforts Percolate

As the federal government grapples with Internet-connected devices and applications that make up the Internet of Things (IoT), the National Institute of Standards and Technology (NIST) is forging ahead to provide "technical leadership" for "the operation, trustworthiness, and lifecycle of IoT". Such efforts complement - and contrast - recent policy efforts at the National Telecommunications and Information Administration (NTIA) and elsewhere to promote IoT innovation while addressing security, privacy, and interoperability.  more

How the Clinton “Village” Transformed Internet Paradigms: Together Making a Difference

U.S. Presidential elections and the resulting Administrations can make an enormous difference on many levels and become profound points of inflection. This reality is certainly starkly visible today. Perhaps for the Internet community as well as the general public, some of the largely unknown events and actions surrounding the Internet and the Clinton team from 25 years ago can provide a basis for engagement over the coming months. more

Is There a Positive Business Case for IPv6? We Are About to Find Out, If You Help Us…

Large-scale IPv6 deployments suggest that IPv6 is at least a technical success, the technology works. Time to visit the other important question: does it work commercially. Does IPv6 really come with a positive business case? We are about to find out, if you help us... The Internet technical community has spent about two decades making IPv6 work on a technical level. We have developed the protocol, modified and expanded a few others; we set up the registry system and distributed the addresses. more

Google’s IPv6 Stats Hit 12% on Fourth Anniversary of World IPv6 Launch

Four years ago today, thousands of websites, including Facebook, Google and Yahoo, and hundreds of networks permanently enabled IPv6 in what was called "World IPv6 Launch". One year before, on June 6, 2011, there had been a 24-hour test in "World IPv6 Day" but by June 6, 2012, IPv6 was enabled permanently for the participating sites and networks. One of the many IPv6 statistics sites many of us have watched since that time has been Google's statistics. more

Why Broadband Speed Tests Suck

Everyone is familiar with broadband 'speed test' applications. When you have an ISP service quality problem, it is common to grab one of these tools to see if you are getting the service you feel you are entitled to get. Whenever you upgrade your broadband, the first thing you might do is to run a speed test. Then you can show off to your mates how superior your blazing fast service is compared to their pitiful product. more

Is IPv6 an Essential Precondition for Internet of Things? Or Are Things Just Fine with IPv4?

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

Broadband Carrier Quandary: Exploit Bandwidth Scarcity, or Reduce It?

Comcast enhanced the value position of its broadband subscriptions by increasing the monthly data allowance to 1 Terrabyte (1000 Gigabytes). See Comcast Announcement. As an independent, unsponsored researcher, I can say "Thank You Comcast" without adverse consequences and only a bit of irony. This company does much to displease, but an expanded data allowance offers a winning proposition. more

Why You Should Demand ‘Net Morality’ Instead of ‘Net Neutrality’

I have come to the conclusion that "net neutrality" is an ethical issue at heart, one about the appropriate constraint of unfair ISP power. Some people are (I pray unintentionally) on the wrong side of a now-clear moral divide. They are claiming to prevent harmful abuse of power, when in reality their actions create fresh harm. A central issue is one of technical competence to comment. If your beliefs are disconnected from how the world works, you cannot evaluate whether you are espousing something sensible or silly. more

On the Internet Everyone is Connected to Everyone Else - Right?

We tend to make a number of assumptions about the Internet, and sometimes these assumptions don't always stand up to critical analysis. We were perhaps 'trained' by the claims of the telephone service to believe that these communications networks supported a model of universal connectivity. Any telephone handset could establish a call with any other telephone handset was the underlying model of a ubiquitous telephone service, and we've carried that assumption into our perception of the Internet. On the Internet anyone can communicate with anyone else - right? more
