Ossification and Fragmentation: The Once and Future ‘net

Mostafa Ammar, out of Georgia Tech recently posted an interesting paper titled The Service-Infrastructure Cycle, Ossification, and the Fragmentation of the Internet. I have argued elsewhere that we are seeing the fragmentation of the global Internet into multiple smaller pieces, primarily based on the centralization of content hosting combined with the rational economic decisions of the large-scale hosting services. The paper in hand takes a slightly different path to reach the same conclusion.

Securing the Routing System at NANOG 74

The level of interest in the general topic of routing security seems to come in waves in our community. At times it seems like the interest from network operators, researchers, security folk and vendors climbs to an intense level, while at other times the topic appears to be moribund. If the attention on this topic at NANOG 74 is anything to go by we seem to be experiencing a local peak.

Google Signs Memoranda of Understanding With Four Cuban Organizations

Cuban President Miguel Díaz-Canel addressed the first annual meeting of Cuba's IT professional society, the Unión de Informáticos de Cuba. In his talk, Díaz-Canel announced that four Cuban organizations - the Havana City Historian's Office, the University of Computer Sciences (UCI), Infomed, Cuba's medical network, and the Ministry of Culture had signed memoranda of understanding (MOUs) with Google.

IPv6 Security Considerations

When rolling out a new protocol such as IPv6, it is useful to consider the changes to security posture, particularly the network's attack surface. While protocol security discussions are widely available, there is often not "one place" where you can go to get information about potential attacks, references to research about those attacks, potential counters, and operational challenges.

BGP Security: A Gentle Reminder that Networking is Business

At NANOG on the Road (NotR) in September of 2018, I participated in a panel on BGP security -- specifically the deployment of Route Origin Authentication (ROA), with some hints and overtones of path validation by carrying signatures in BGP updates (BGPsec). This is an area I have been working in for... 20 years? ... at this point, so I have seen the argument develop across these years many times, and in many ways.

Getting on with Digital Transformation: Three Steps to Making Strategic Technology Choices

In a recently published Uptime Institute Survey, Uptime Institute found that organizations operating data centers are finding it increasingly difficult to recruit professionals skilled in security, networking, and hybrid technologies. This realization comes at an interesting time, as the monolithic business infrastructure built over the last two decades is now entering a period of transformation.

Join the Quantum Internet Hackathon 2018

The eighth RIPE NCC hackathon takes on the Quantum Internet! The hackathon will be held during the weekend before RIPE 77 in Amsterdam, and is co-organised by QuTech and TU Delft, along with the RIPE NCC. We're bringing together network operators, quantum networking researchers, students, hackers, software developers and artists, to imagine and build the tools for the future Internet.

Nerd Knobs and Open Source in Network Software

Tech is commoditizing. I've talked about this before; I think networking is commoditizing at the device level, and the days of appliance-based networking are behind us. But are networks themselves a commodity? Not any more than any other system. We are running out of useful features, so vendors are losing feature differentiation. This one is going to take a little longer...

DNSSEC and DNS over TLS

The APNIC Blog has recently published a very interesting article by Willem Toorop of NLnet Labs on the relationship between Security Extensions for the DNS (DNSSEC) and DNS over Transport Layer Security. Willem is probably being deliberately provocative in claiming that "DoT could realistically become a viable replacement for DNSSEC." If provoking a reaction was indeed Willem's intention, then he has succeeded for me, as it has prompted this reaction.

Community Networks Could Help Strengthen the Caribbean Internet

By some estimates, only half of the world's population has internet access, leaving the other half at a sizeable competitive disadvantage. This profound connectivity gap is especially significant in the unserved and underserved areas of developing and least-developed countries. For people who live in these places, Internet connectivity is not just about the Internet. It is a lifeline that gives access to electronic commerce and telehealth services, distance learning, social and political engagement, government services...
