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

Is the FCC Inviting the World’s Cyber Criminals into America’s Living Rooms?

In October 2012, the Chairman and Ranking Member of the House Intelligence Committee issued a joint statement warning American companies that were doing business with the large Chinese telecommunications companies Huawei and ZTE to "use another vendor." The bipartisan statement explains that the Intelligence Committee's Report, "highlights the interconnectivity of U.S. critical infrastructure systems and warns of the heightened threat of cyber espionage and predatory disruption or destruction of U.S. networks if telecommunications networks are built by companies with known ties to the Chinese state, a country known to aggressively steal valuable trade secrets and other sensitive data from American companies." more

Declaring IPv6 an Internet Standard

I've already shared my thoughts following a session of the IPv4 Sunset Working Group at IETF 95 that considered whether to declare IPv4 an "Historic" specification. Of course, as one would expect for a meeting of a Standards Development Organization (SDO), that wasn't the only standards process discussion through the week. Another session, this time in the IPv6 Maintenance Working Group, considered the related topic of whether to make the IPv6 specification a full Internet Standard. Let's look at that proposal. more

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. more

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. more

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. more

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. more

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. more

Internet Society Applauds Plan to Transition Oversight of Key Internet Resources

The Internet Society (ISOC) Board of Trustees today passed a resolution to strongly support the plan developed by the global Internet community presented to the U.S. National Telecommunications and Information Administration to transition oversight of key Internet resources. more

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. more

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. more

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. more

IPv4 Market Outlook

When 2015 began, there were several million IPv4 numbers still in the American Registry for Internet Numbers (ARIN) IPv4 free pool, ARIN was processing 4-5 unique IPv4 transfer transactions per month, and fewer than 5 million numbers had been transferred publicly in the prior 12 months. The end of 2015 told a different story. In late September, the ARIN free pool was depleted. more

Reflections on NANOG 66

The North American Network Operators Group (NANOG) continues to be one of the major gatherings on network operators and admins, together with the folk who work to meet the various needs of this community. Their program committee produces a program that never fails to provide thought provoking interest. Here are my reactions to some of the presentations I heard at NANOG 66, held in San Diego in February. more

Can We Really Blame DNSSEC for Larger-Volume DDoS attacks?

In its security bulletin, Akamai's Security Intelligence Response Team (SIRT) reported on abuse of DNS Security Extensions (DNSSEC) when mounting a volumetric reflection-amplification attack. This is not news, but I'll use this opportunity to talk a bit about whether there is a trade-off between the increased security provided by DNSSEC and increased size of DNS responses that can be leveraged by the attackers. more
