How DANE Strengthens Security for TLS, S/SMIME and Other Applications

The Domain Name System (DNS) offers ways to significantly strengthen the security of Internet applications via a new protocol called the DNS-based Authentication of Named Entities (DANE). One problem it helps to solve is how to easily find keys for end users and systems in a secure and scalable manner. It can also help to address well-known vulnerabilities in the public Certification Authority (CA) model. Applications today need to trust a large number of global CAs. more

Did We Build the ‘Right’ Internet? (An Interview with Prof Andrew Russell)

The longer I have been in the tech industry, the more I have come to appreciate the hidden complexity and subtlety of its past. A book that caught my attention is 'Open Standards and the Digital Age' by Prof Andrew Russell of Stevens Institute of Technology in New Jersey. This important work shines a fresh light on the process that resulted in today's Internet. For me, it places the standard 'triumphant' narrative of the rise of TCP/IP into a more nuanced context. more

Telecoms Infrastructure As a Service

More than a decade ago we predicted that the telecoms industry would be transformed, driven by its own innovations and technological developments. As a result we indicated that in many situations the telecommunications infrastructure would be offered as a service by hardware providers. We also predicted that this would open the way for a better sharing of the infrastructure. more

Connecting the Next Billion. Is It Possible? (An African Perspective)

This year, the IGF Multistakeholder Advisory Group which provide assistance in the preparations for Global IGF meetings called for Intersessional work (activities that are pursued in the months between annual IGFs with the aim of helping the IGF produce more tangible outputs that can become robust resources). Previously, the IGF has used best Practice Forums and Dynamic coalitions to bring out key issues that affect the world as it relates to the Internet. This year's Intersessional activity is centred on "Policy Option for connecting the Next Billion". more

How to Tame Network Complexity

In a previous article, I discussed how telecoms is facing a growing complexity crisis. To resolve this crisis, a new approach is required. Here I explore how that complexity can be tamed... 'Invariants' are things that are meant to be 'true' and stay true over time. Some invariants are imposed upon us by the universe... Others are imposed by people. As engineers, we aim to establish these abstract 'truths' about the system. more

Zero-Rating vs. The Internet

Reading about the EU Neutrality vote, I'm reminded of the challenge faced by traditional telecommunications regulators in understanding the very concept of the Internet. To put it bluntly zero-rate is a policy framed in terms of Minitel and setting the price based on what phone number is dialed and not at all about the Internet where the value is determined by relationships entirely outside of a network. more

Future Network Forum to Be Held in Nanjing in December 2015

Between December 10th and 11th 2015, the China Future Network Development and Innovation Forum, jointly hosted by the Chinese Academy of Engineering and the Nanjing Municipal Government, is scheduled to be held in Nanjing, Jiangsu, China. The forum will be jointly organized by Jiangsu Future Networks Innovation Institute and Beijing Internet Institute, with the theme of "Building future network test facilities and promoting network development & innovation", and it will invite nearly a hundred industrial experts at home and abroad, to establish a platform marked by security, innovation, openness, cooperation where the policy, industry, academics, and application are integrated. more

Why IPv6 Deployment is Slow in Africa & What to Do About It

We (the global corps of IPv6 evangelists) have done the trainings (over 200 training sessions in about 45 countries in Africa alone and counting). We've done the conferences (several variations of IPv6 World, IPv6 Business Conferences, IPv6 Hours and Days at the Africa Internet Summits, etc). We've even done the global coordinated events -- IPv6 World Launch. Governments have found it trendy to launch IPv6 Task Forces and come up with National Action Plans for IPv6. Now, almost more than 2000 network engineers (across Africa), thousands of hours of speeches and presentations, hundreds of blog articles and webinars later, where are we? more

NANOG 65 Report

NANOG 65 was once again your typical NANOG meeting: a set of operators, vendors, researchers and others for 3 days, this time in Montreal in October. Here's my impressions of the meeting... The opening keynote was from Jack Waters from Level 3, which looked back over the past 25 years of the Internet, was interesting to me in its reference to the "Kingsbury Letter". more

Thoughts on the Open Internet - Part 5: Security

Any form of public communications network necessarily exposes some information about the identity and activity of the user's of its services. The extent to which such exposure of information can be subverted and used in ways that are in stark opposition to the users' individual interests forms part of the motivation on the part of many users to reduce such open exposure to an absolute minimum. The tensions between a desire to protect the user through increasing the level of opacity of network transactions to third party surveillance, and the need to expose some level of basic information to support the functions of a network lies at the heart of many of the security issues in today's Internet. more

Mobile Broadband Penetration in Asia

The advent of mobile broadband triggered a huge change in broadband access across Asia. Following more than a decade of strong growth in almost all mobile markets in the region, an amazing transition to new generation mobile networks and services took place. By end 2014 there were a total of 1.2 billion mobile subscribers and with annual growth running at over 40% coming into 2015 the numbers were expected to hit 1.7 billion by end-2015. more

Thoughts on the Open Internet - Part 4: Locality and Interdependence

The Internet was not originally designed as a single network that serviced much of the world's digital communications requirements. Its design was sufficiently flexible that it could be used in many contexts, including that of small network domains that were not connected to any other domain, through to large diverse systems with many tens of thousands of individual network elements. If that is indeed the case, then why is it that when networks wish to isolate themselves from the Internet, or when a natural calamity effectively isolates a network, the result is that the isolated network is often non-functional. more

Thoughts on the Open Internet - Part 2: The Where and How of “Internet Fragmentation”

In defining what is meant by "Internet Fragmentation" it is useful to briefly describe what is meant by its opposite, an "Open and Coherent Internet". As we've explored in the previous section, "coherence" implies that each of the elements of the Internet are orchestrated to work together to produce a seamless Internet which does not expose the boundaries between discrete elements. more

Why We Need Gigabit Networks

There is currently a great deal of debate regarding the need for gigabit networks. There are still a lot of voices, often led by conservative political and media people, who argue that hardly anyone needs such networks. Unfortunately for them, however, their arguments are totally flawed. And who are they, anyway, to set the tone for such new infrastructure. Isn't necessity the mother of invention? more

U.S. and China Negotiating Cyeberwarfare Control Deal

United States and China are in negotiation to establish a cyberattack agreement, according to reports. If successful, it "could become the first arms control accord for cyberspace, embracing a commitment by each country that it will not be the first to use cyberweapons to cripple the other's critical infrastructure during peacetime," reports David Sanger in the New York Times. more
