The Network is the Computer

The Network is the Computer

We recently registered the trademark for The Network is the Computer®, to encompass how Cloudflare is utilizing its network to pave the way for the future of the Internet.

The phrase was first coined in 1984 by John Gage, the 21st employee of Sun Microsystems, where he was credited with building Sun’s vision around “The Network is the Computer.” When Sun was acquired in 2010, the trademark was not renewed, but the vision remained.

Take it from him:

“When we built Sun Microsystems, every computer we made had the network at its core. But we could only imagine, over thirty years ago, today’s billions of networked devices, from the smallest camera or light bulb to the largest supercomputer, sharing their packets across Cloudflare’s distributed global network.
We based our vision of an interconnected world on open and shared standards. Cloudflare extends this dedication to new levels by openly sharing designs for security and resilience in the post-quantum computer world.
Most importantly, Cloudflare is committed to immediate, open, transparent accountability for network performance. I’m a dedicated reader of their technical blog, as the network becomes central to our security infrastructure and the global economy, demanding even more powerful technical innovation.

Configuring MACsec Encryption

This article describes the simplest way to enable MACSec using preconfigured static key-string. The example was tried on Catalyst 3850 and should work on other switches too. There is another article that I wrote years ago which describes a more complex implementation with dot1x etc. MACSec Media Access Control Security is the way to secure point-to-point Ethernet links by implementing data integrity check and encryption of Ethernet frame. When you configure MACsec on a switch interface (and of course, on the other switch connected to that interface), all traffic going through the link is secured using data integrity checks and encryption.

How network pros acquire skills for SDN, programmable networks

Jason Pichardo’s career path has mirrored the changes in networking over the past decade, moving from a traditional hardware-dominated past to a software-centric future that reflects the network’s growing importance to business operations.“The industry started having conversations about digital transformation, and already we have moved to a hybrid-cloud state with programmability and orchestration. We’ve gone from talking about switches and routers to talking about how to speed to market faster and how to accomplish business tasks at a faster rate,” says Pichardo, senior network architect at insurance provider Anthem.

Intel unveils new 3D chip packaging design

Intel has unveiled a new packaging innovation for creating 3D chip packages and multiple chip connections ahead of the Semicon West conference in San Francisco this week.The company is detailing its Embedded Multi-Die Interconnect Bridge (EMIB) technologies and Foveros 3D chip packages. This may sound like very inside baseball and best suited for the propellerhead crowd, but hear me out.[ Also read: What is quantum computing (and why enterprises should care) ] Chip packaging has always played a critical role in semiconductors, and it’s getting more important as chipmakers such as Intel and AMD strain against the limits of Moore’s Law. The chip’s package is how the chip’s electrical signals and power are routed.To read this article in full, please click here

Day Two Cloud 013: To Do Cloud Right, Leave Data Center Thinking Behind

Organizations don't have to be convinced to adopt the cloud these days. The conversation now is about how to do it right. Guest Dwayne Monroe joins the Day Two Cloud podcast to talk about how to change your thinking about cloud in terms of resource sizing, cost, staff training, service availability, app refactoring and much more.

Cloudflare’s Karma, Managing MSPs, & Agile Security

Cloudflare come out strong, pointing the finger at Verizon for shoddy practices putting the Internet at risk. It didn’t take long for karma to come around and for Cloudflare to have their own Internet impacting outage from a mistake of their own. In this episode we talk about that outage, the risk of centralization on the Internet, managing MSPs when trouble strikes, and whether or not agile processes are forgoing security in favor of faster releases.

The Titan supercomputer is being decommissioned: a costly, time-consuming project

A supercomputer deployed in 2012 is going into retirement after seven years of hard work, but the task of decommissioning it is not trivial.The Cray XK7 “Titan” supercomputer at the Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) is scheduled to be decommissioned on August 1 and disassembled for recycling.At 27 petaflops, or 27 quadrillion calculations per second, Titan was at one point the fastest supercomputer in the world at its debut in 2012 and remained in the top 10 worldwide until June 2019.[ Also read: 10 of the world's fastest supercomputers | Get regularly scheduled insights: Sign up for Network World newsletters ] But time marches on. This beast is positively ancient by computing standards. It uses 16-core AMD Opteron CPUs and Nvidia Kepler generation processors.

A gentle introduction to Linux Kernel fuzzing

A gentle introduction to Linux Kernel fuzzing

For some time I’ve wanted to play with coverage-guided fuzzing. Fuzzing is a powerful testing technique where an automated program feeds semi-random inputs to a tested program. The intention is to find such inputs that trigger bugs. Fuzzing is especially useful in finding memory corruption bugs in C or C++ programs.

A gentle introduction to Linux Kernel fuzzing

Normally it's recommended to pick a well known, but little explored, library that is heavy on parsing. Historically things like libjpeg, libpng and libyaml were perfect targets. Nowadays it's harder to find a good target - everything seems to have been fuzzed to death already. That's a good thing! I guess the software is getting better! Instead of choosing a userspace target I decided to have a go at the Linux Kernel netlink machinery.

Netlink is an internal Linux facility used by tools like "ss", "ip", "netstat". It's used for low level networking tasks - configuring network interfaces, IP addresses, routing tables and such. It's a good target: it's an obscure part of kernel, and it's relatively easy to automatically craft valid messages. Most importantly, we can learn a lot about Linux internals in the process. Bugs in netlink aren't going Continue reading

Will rolling into IBM be the end of Red Hat?

IBM's acquisition of Red Hat for $34 billion is now a done deal, and statements from the leadership of both companies sound extremely promising. But some in the Linux users have expressed concern.Questions being asked by some Linux professionals and devotees include: Will Red Hat lose customer confidence now that it’s part of IBM and not an independent company? Will IBM continue putting funds into open source after paying such a huge price for Red Hat? Will they curtail what Red Hat is able to invest? Both companies’ leaders are saying all the right things now, but can they predict how their business partners and customers will react as they move forward? Will their good intentions be derailed? Part of the worry simply comes from the size of this deal. Thirty-four billion dollars is a lot of money. This is probably the largest cloud computing acquisition to date. What kind of strain will that price tag put on how the new IBM functions going forward? Other worries come from the character of the acquisition – whether Red Hat will be able to continue operating independently and what will change if they cannot. In addition, a few Linux devotees hark Continue reading

Wireless alliance: You might want to move some access points for Wi-Fi 6

Businesses could find themselves repositioning wireless access points and even facing increased bandwidth demands as Wi-Fi 6 hits the market in the coming months, according to a white paper released today by the Wireless Broadband Alliance.Nevertheless, the news is mostly good for prospective business users. Thanks to Wi-Fi 6’s array of coexistence, power-saving and smart management features, a new network based on the technology shouldn’t pose many deployment problems.The time of 5G is almost here Key to the enterprise WLAN use case, the white paper says, is deployment planning – Wi-Fi 6 can offer different optimal placement options than previous-generation Wi-Fi, so it could behoove upgraders to consider changing AP locations, instead of just swapping out existing devices in the same locations.To read this article in full, please click here
