The Strange Structure of ISP Service Semantics

I have been having a number of conversations recently with several clients and colleagues about "semantics". It's clear that there is not a lot of clarity on this philosophical subject! Whilst is may be an obscure issue, it is a very important one. Our ideas lead us to take actions, and if we want those actions to have the consequences we had in mind, then we need to have done our epistemological homework.

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.

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.

Electricity Utilities and IoT

More and more connected devices will require more and better electricity solutions. In many developing economies more people have ready access to a smartphone and the internet than they have access to electricity. For that reason we have seen mobile telecoms operators starting to include power solutions (mainly through distributed energy systems, using solar panels) in order to sell more phones and telecom services. This shows how important access to electricity is.

Government-Industry Collaboration Is Better than Developing a Surveillance State

President Obama, in March 2016, again stressed the need for better collaboration between the tech industry and the government. He referred to his own White House initiative - this has resulted in the newly-formed US Digital Service, which is trying to recruit the tech industry to work with and for government. One of the key reasons it is so difficult to establish trustworthy, good working relationships is the extreme lack of tech understanding among most politicians and government bureaucrats.

SIP Trunking: Common Pitfalls and Quick Fixes

With companies shifting away from on-premises and "traditional" telecom networks to Internet-based protocols - such as Voice Over IP (oIP) - the market for critical communications infrastructure - most notably SIP trunking - is on the rise; not only multiple failover sites but cloud-based SIP-as-a-service solutions are now popular options. However, there's a caveat: problems unique to SIP systems that can cause IT headaches if you're not prepared. Here are three of the most common.

An Unprecedented Look Into Utilization at Internet Interconnection Points

Measuring the performance of broadband networks is an important area of research, and efforts to characterize the performance of these networks continues to evolve. Measurement efforts to date have largely relied on in­home devices and are primarily designed to characterize access network performance. Yet, a user's experience also relies on factors that lie upstream of ISP access networks, which is why measuring interconnection is so important.

Blocking and Filtering in Collaborative Security Context - A Reflection on RFC 7754

The other day, I planned to take my 15-year-old son to the movie theatre to see "Hateful Eight" in 70mm film format. The theatre would not allow him in. Under article 240a of the Dutch penal code, it is a felony to show a movie to a minor when that movie is rated 16 or above. Even though I think I am responsible for what my son gets to see, I understand that the rating agency put a 16-year stamp on this politically-incorrect-gun-slinging-gore-and-curse-intense-comedy feature.

What Your ISP (Probably) Knows About You

Earlier this week, I came across a working paper from Professor Peter Swire - a highly respected attorney, professor, and policy expert. Swire's paper, entitled "Online Privacy and ISPs", argues that ISPs have limited capability to monitor users' online activity. The paper argues that ISPs have limited visibility into users' online activity for three reasons: (1) users are increasingly using many devices and connections, so any single ISP is the conduit of only a fraction of a typical user's activity; (2) end-to-end encryption is becoming more pervasive, which limits ISPs' ability to glean information about user activity; and (3) users are increasingly shifting to VPNs to send traffic.

Decoding the Cellular IoT Acronym Alphabet Soup

Do you know what all these acronyms and abbreviations mean related to cellular networks and the Internet of Things (IoT)? MTC, Cat-0, Cat-1, Cat-M1, LTE-M, NB-IoT, EC-GSM, LPWA, eDRX, PSM... I certainly didn't, but Tuomas Tirronen at Ericsson Research wrote a blog post titled "Cellular IoT alphabet soup" where he explained all of this for those of us who might be interested.
