What Is the World Community Grid?

Innovation is one of those words that is a bit hard to internalize. Merriam-Webster says innovation is the introduction of something new or a new idea, method, or device. That would be a narrow definition, perhaps even obsolete. Innovation is much more than invention or introducing new technology. Some would say that innovation is more of a state of mind, an attitude. One thing is for sure: innovation is happening more quickly; it is more open and more collaborative.

The Test of Time at Internet Scale: Verisign’s Danny McPherson Recognized with ACM SIGCOMM Award

The global internet, from the perspective of its billions of users, has often been envisioned as a cloud -- a shapeless structure that connects users to applications and to one another, with the internal details left up to the infrastructure operators inside. From the perspective of the infrastructure operators, however, the global internet is a network of networks. It's a complex set of connections among network operators, application platforms, content providers and other parties.

Holding Times – A Phenomenon Happening With ISP Networks That No One Seems to Talk About

During the last year, we saw a big change in the nature of our broadband usage in that many of us are connecting to remote work or school servers, or we are connecting to long Zoom calls. We already can see that these changes have accelerated the average home usage of broadband. OpenSignal reports that the average broadband usage per home grew from 274 gigabytes per month just before the pandemic up to 462 gigabytes per month measured at the end of the first quarter of this year.

Transparency Meets Sustainability: Announcing the SDIA Open Data Hub

Last month, the Sustainable Digital Infrastructure Alliance (SDIA) announced our Open Data Hub, a resource that's meant to boost transparency, trust, and data availability to help researchers, industry, and society realize a sustainable digital economy. It is essentially our answer to the challenge recognized across the sector: that the lack of reliable data is one of the most foundational issues we face in creating a sustainable ICT ecosystem.

The Irrationality of Deploying IPv6

For the past few decades, there's been a relatively straightforward narrative on the economics behind the IPv6 transition that goes something like this: sooner or later, IPv4 scarcity will drive costs up until they exceed those of deploying IPv6. A competitive market will then make the rational choice and transition to a more efficient mode of production and deploy IPv6. This is textbook economics, and - with the disclaimer that I'm not a trained economist - it appears to be incorrect.

Another Portent of the Decline and Fall of the Telco

The Swedish carrier group Telia has recently announced the sale of its international wholesale business to Polhelm Infra, an infrastructure investment manager jointly owned by a number of Swedish pension funds. Why would a telco operator sell off what was a core part of its operation to a pension fund? The Internet was originally conceived as a telephone network for computers. (I should mention that this was not a concept that was unique to the Internet at the time.

New Innovations in Free Space Optics

I read an article on the Finley Engineering blog that talks about new research with free-space optics. For those not familiar with the term, this means communication gear that communicates directly using light without any wires. The article talks about a Chinese team of scientists who have used light to transmit ultrahigh-definition video signals between high-rise buildings.

The Risk Factors of CDNs and Centrality

On the afternoon of June 17 of this year, there was a widespread outage of online services. In Australia, it impacted three of the country's largest banks, the national postal service, the country's reserve bank, and one airline operator. Further afield from Australia, the outage impacted the Hong Kong Stock Exchange and some US airlines. The roll call of affected services appeared to reach some 500 serv

Deadline of July 2 to Nominate People for Jonathan B. Postel Service Award

Do you know of someone who has made the Internet better in some way who deserves more recognition? Maybe someone who has helped extend Internet access to a large region? Or wrote widely-used programs that make the Internet more secure? Or served in some capacity behind the scenes in Internet services? Or maybe someone who has been actively working for open standards and open processes for the Internet?

New Hair-Like Plastic Polymer Cable Can Transmit Data Ten Times Faster Than Copper

Scientists and engineers are always looking for ways to speed up and more efficiently configure computing devices to maximize data flow. There are a lot of applications today that require the exchange of huge volumes of data in real-time. MIT scientists have created a hair-like plastic polymer cable that can transmit data ten times faster than copper USB cables.
