Fiber transmission range leaps to 2,500 miles, and capacity increases

Fiber transmission could be more efficient, go farther, carry more traffic and be cheaper to implement if the work of scientists in Sweden and Estonia is successful.In a recent demonstration, researchers at Chalmers University of Technology, Sweden, and Tallinn University of Technology, Estonia, used new, ultra-low-noise amplifiers to increase the normal fiber-optic transmission link range six-fold.And in a separate experiment, researchers at DTU Fotonik, Technical University of Denmark used a unique frequency comb to push more than the total of all internet traffic down one solitary fiber link.[ Read also: How Google is speeding up the Internet ] Fiber transmission limits Signal noise and distortion have always been behind the limits to traditional (and pretty inefficient) fiber transmission. They’re the main reason data-send distance and capacity are restricted using the technology. Experts believe, however, that if the noise that’s found in the amplifiers used for gaining distance could be cleaned up and the signal distortion inherent in the fiber itself could be eliminated, fiber could become more efficient and less costly to implement.To read this article in full, please click here

Improving DevOps Security Practices

Tales from the field: Best practices for initial provisioning (Part 1)

Working with the Cumulus Professional Services team, we get the privilege of seeing how many folks use and operationalize Cumulus Linux. Over time, we’ve learned many lessons and best practices that can benefit others who are getting started on the journey. It’s for that reason that we’re putting virtual pen to virtual paper and writing this post. This article is the first in a series of two that will discuss how to use Zero Touch Provisioning (ZTP) and automation tools together for maximum efficiency in your initial provisioning. This post is going to focus on ZTP while the next will focus on automation tooling.

Cumulus Linux: Batteries included

Let’s recap — what comes configured with Cumulus out of the box?

• 2 user accounts (cumulus and root, but only cumulus supports login via a default password
• Some COntrol Plane Policing (COPP) rules that limit lots of different types of control traffic
• SSHv2 enabled by default
• NTP enabled by default

You’ll notice here that we’ve said nothing about interface configuration. Like all network switches and routers we start with a pretty blank slate from an interface configuration perspective. We leverage ZTP to give us some initial configuration for the node to use Continue reading

Three new ways teams are using Cloudflare Access

Since leaving beta three weeks ago, Cloudflare Access has become our fastest-growing subscription service. Every day, more teams are using Access to leave their VPN behind and connect to applications quickly and securely from anywhere in the world.

We’ve heard from a number of teams about how they’re using Access. Each team has unique needs to consider as they move away from a VPN and to a zero trust model. In a zero trust framework, each request has to prove that a given application should trust its attempt to reach a secure tool. In this post, we’re highlighting some of the solutions that groups are using to transition to Cloudflare Access.

Solution 1: Collaborate with External Partners

Cloudflare Access integrates with popular identity providers (IdPs) so that your team can reach internal applications without adding more credentials. However, teams rarely work in isolation. They frequently rely on external partners who also need to reach shared tools.

How to grant and manage permissions with external partners poses a security risk. Just because you are working with a third-party doesn’t mean they should have credentials to your IdP. They typically need access to a handful of tools, not all of your internal Continue reading

CCNA Routing & Switching

I would arguably say that Keith is the best CCNA instructor in the nation. The interaction in this class is key. Listening to a lesson doesn’t ensure comprehension, so Keith offered periodic quizzes; not only did this make the course increasingly interactive but also verified your understanding of the technologies discussed.

I very much look forward to going to the CCNP bootcamps. Thank you again Keith and staff for making my learning experience a great one!
Thomas Osborne – CCNA

CCNP ROUTE

The instructor Keith is very knowledgeable, patient, and polite. He covered everything possible with the amount of time we had. I also like the format of having to take routing and switching separately.

We Must Continue to Advocate Passionately and Fearlessly: An Interview with Our CEO, Kathy Brown

Late November, Kathy Brown announced that she would be stepping down as CEO of the Internet Society. While preparing for her next chapter, she reflected on her time at the Internet Society and shared her thoughts on how the Internet itself has evolved during her tenure.

The Internet Society: What are the biggest changes you’ve seen in the Internet since you joined the Internet Society?

Kathy Brown: When I joined the Internet Society nearly five years ago, there were about 3 billion people online. Since then, that number has grown by almost a billion, but, still, not everyone is connected. The Internet Society has helped bring Internet access to the hardest-to-reach places on earth, including remote regions in the Caucasus and indigenous communities in South America, but there remain twice as many people online in the developed world than in the developing world, and the digital gender gap is widening.

There’s also been a trend toward consolidation, with fewer companies controlling more and more, and the Internet getting increasingly centralized. We’ve seen governments using the Internet in good, but also bad ways, such as shutdowns, and we’ve seen criminals finding ways to exploit it.

BrandPost: Loyal to a Fault: Why Your Current DNS May Be Exposing You to Risk

Ask seasoned IT professionals what they dislike most about their infrastructure, and they’ll answer in unison: Change. IT, network and security professionals all rely on tried-and-true products to keep the business humming along, but is doing so exposing them to new risks? This post looks at some hidden risk factors present in many of today’s DNS environments, and what enterprises should be doing now to ameliorate them.There are very few organizations more change-averse than enterprise IT professionals – especially their network and security teams. With network stability (read uptime) at the heart of their existence, reliance on known products and services can become a crutch – and a blindfold, limiting the ability to objectively consider new infrastructure solutions. As the advent of cloud came upon IT, many organizations needed to fight the ‘server-huggers’, who insisted that their sacred server or device located in the datacenter was the only way to run a specific application or perform a specific business function.To read this article in full, please click here
