The Impacts of Hurricanes Harvey, Irma, and Maria on the Internet

The devastation caused by several storms during the 2017 Atlantic hurricane season has destroyed neighborhoods and taken lives across a number of Caribbean island nations including Texas and Florida in the United States. Senior Director of Internet Research & Analysis at Oracle Dyn Global Business Unit has posted a blog that takes a look at the impacts. more

Network Dis-Aggregation and SDN: Different, But Related

Two of the hottest trends in networking today are network dis-aggregation and SDN. This is great for many reasons. It's also confusing. The marketing hype makes it hard to understand either topic. SDN has become so vague that if you ask 10 experts what it means, you are likely to get 12 different answers. Network dis-aggregation seems straightforward enough until it gets confused with SDN. We need to take a step back. In a recent Packet Pushers blog post; I start with a simple explanation of each of these trends and then map how they interact. more

OpenFlow - The Programmable Network Revolution

Over the past few months I have made regular references to OpenFlow. This is an exciting new development that fits in very well with several of the next generation technology developments that we have discussed in some detail over the past few years -- new developments such smart cities and smart societies, the internet of things. Such networks need to operate more on a horizontal level, rather than the usual vertical connection between a computing device and the users. more

Hyperconvergence, Disaggregation, and Cloud: The Foggy Future of Network Engineering

The world of networking tends to be bistable: we either centralize everything, or we decentralize everything. We started with mainframes, passed through Lotus 123 hidden in corners, then to mini's and middleware, then to laptops, and now to the cloud, to be followed by fog. This particular cycle of centralization/decentralization, however, has produced a series of overlapping changes that are difficult to decipher. You can somehow hear someone arguing about disaggregation and hyperconvergence through the fog -- but just barely. more

Don’t Make the Internet Safe for Monopolies

This week I'm going to Washington to argue against regulating Internet access as if it were phone service. Twenty years ago I was there for the same reason. My concern now as it was then is that such regulation will damage the economy and reduce opportunity by stifling innovation and protecting the current dominant players from the startups which would otherwise threaten them. more

Measuring IPv6 at the Network and the Customer Level

George Michaelson, APNIC's Senior Research and Development Scientist recently visited the RIPE NCC to collaborate on various research projects with his RIR colleagues. IPv6 measurements were one of the topics we looked at. Recent IPv6 statistics from the RIPE NCC show an accelerated uptake of IPv6 in Norway, both in terms of the number of allocated prefixes, and visible announcements in the routing system. more

Why Over Compliance With Sanctions at Internet Infrastructure Level Can Have Devastating Effects on Ordinary People

On Friday, Mykhailo Fedorov, Ukraine's digital transformation minister, asked Cloudflare and Amazon to stop serving Russian web resources and protecting Russian services. He said in a tweet that Ukraine was "calling on Amazon to stop providing cloud services in Russia." He also said that "Cloudflare should not protect Russian web resources while their tanks and missiles attack our kindergartens." more

IPv6 Enabled Networks Before and After World IPv6 Day

In our last post on CircleID, Measuring World IPv6 Day - First Impressions, we showed exactly when World IPv6 Day participants switched on IPv6 on their networks (by way of announcing DNS AAAA records). Now, a few weeks after World IPv6 Day, it's interesting to see what the longer-term effects have been. more

Is the Passion Over Net Neutrality Misguided? A New Paper Offers a Fresh Technical Approach

"Net neutrality" is implicitly framed as a debate over how to deliver an equitable ration of quality to each broadband user and application. This is the wrong debate to have, since it is both technically impossible and economically unfair. We should instead be discussing how to create a transparent market for quality that is both achievable and fair. In this paper I propose an alternative approach that (potentially) meets the needs of both consumer advocates and free market proponents. 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

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

Traffic Management: An Undefined Term

In Europe yet another package is discussed, and it includes issues related to what I guess one could call Network Neutrality. And, as usual, at the end of the game, texts are negotiated that does not have much meaning in reality. Negotiations on what words imply, while I as an engineer have absolutely no idea what either of the parties actually mean... more

Flipping the Kill Switch: Internet Restrictions Becoming the New Normal

The Internet was built on the promise that everyone, everywhere could create, share information and ideas without frontiers. Yet, Internet restrictions are increasing to the point they are becoming the norm. And it's happening fast. In its 2016 Freedom on the Net report, Freedom House revealed that Internet freedom declined for the 6th year in a row. The report notes that more governments have been blocking social media and communication apps than ever before. more

Data Breaches Reported During 2016 Exposed Over 4.2 Billion Records

2016 broke the previous all-time high, set back in 2013, for the number of records exposed from reported data breaches. more

Study Finds IPv6 Adoption Exposes More Residential Devices to Unsolicited Traffic

As IPv6 adoption accelerates, a new study warns that the disappearance of NAT in home networks is exposing millions of devices to online threats -- potentially fueling a new wave of powerful IoT botnets. more
