The company is using SDN technology to combine service edge routers for Ethernet and IP-based services. Software control will come from a single common compute platform based on x86 architecture.
The Open SD-WAN Exchange (OSE) plans to launch its service level API, which helps SD-WAN vendors talk, at the upcoming ONUG Spring 2018 conference.
Microsoft reported cloud revenues of $6 billion, while AWS reported revenues of $5.4 billion for the quarter.
Have you ever wondered why spine-and-leaf networks are the “standard” for data center networks? While the answer has a lot to do with trial and error, it turns out there is also a mathematical reason the fat-tree spine-and-leaf is is used almost universally. There often is some mathematical reason for the decisions made in engineering, although we rarely explore those reasons. If it seems to work, there is probably a reason.
The fat-tree design is explored in a paper published in 2015 (available here at the ACM, and now added to my “classic papers” page so there is a local copy as well), using a novel technique to not only explore why the spine-and-leaf fat-tree is so flexible, but even what the ideal ratio of network capacity is at each stage. The idea begins with this basic concept: one kind of network topology can be emulated on top of another physical topology. For instance, you can emulate a toroid topology on top of a hierarchical network, or a spine-and-leaf on top of of hypercube, etc. To use terms engineers are familiar with in a slightly different way, let’s call the physical topology the underlay, and the emulated topology the overlay.

In Part 1 of Getting Started with Terraform, we explained how Terraform lets developers store Cloudflare configuration in their own source code repository, institute change management processes that include code review, track their configuration versions and history over time, and easily roll back changes as needed.
We covered installing Terraform, provider initialization, storing configuration in git, applying zone settings, and managing rate limits. This post continues the Cloudflare Terraform provider walkthrough with examples of load balancing, page rules, reviewing and rolling back configuration, and importing state.
Before we build on Part 1, let's quickly review what we configured in that post. Because our configuration is in git, we can easily view the current configuration and change history that got us to this point.

Why BGPSec turned out the way it did ?
Well, not exactly Fishin', but I'll be on a month long vacation starting today. I won't be posting new content, so we'll all have a break. Disappointing, I know. Please use this time for quiet contemplation and other inappropriate activities. Se vidiva kmalu!

In 2017, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. In April 2018, we interviewed two stakeholders –Getachew Engida, Deputy Director-General of the United Nations Educational, Scientific and Cultural Organization (UNESCO), and Augusto Mathurin, who created Virtuágora, an open source digital participation platform – to hear their different perspectives on the forces shaping the Internet.
Augusto Mathurin is a 25-year-old Argentinian who strongly believes in the need to enable all people to participate in decision-making which can impact them and their communities. With this in mind, Augusto developed an open source digital participation platform as part of a university project. The main goal of this platform, Virtuágora, was to create a common space in which citizens’ opinions and their representatives’ proposals could converge. The concept was derived from the Greek agora – the central square of ancient Grecian cities where citizens met to discuss their society. In 2017, Augusto was awarded the Internet Society’s 25 under 25 award for making an impact in his community and beyond. (You can Continue reading
Breaking into any part of the IT stack against incumbents with vast installed bases is not easy task. Cutting edge technology is table stakes, and targeting precise customers with specific needs is the only way to get a toehold. It also takes money. Lots of money. Innovium, the upstart Ethernet switch chip maker, has all three and is set to make some inroads among the hyperscalers and cloud builders.
We told you all about Innovium back in March last year, when the company, founded by former networking executives and engineers from Intel and Broadcom, dropped out of stealth and …

Getachew Engida is the Deputy Director-General of UNESCO. He has spent the past twenty years leading and managing international organizations and advancing the cause of poverty eradication, peace-building, and sustainable development. He has worked extensively on rural and agricultural development, water and climate challenges, education, science, technology and innovation, intercultural dialogue and cultural diversity, communication and information with emphasis on freedom of expression, and the free flow information on and offline.
