Scientists Create a Long-Distance Cryogenic Microwave Quantum Network

There’s been quite a bit of fanfare around quantum computing during the last few years, with experts predicting that quantum computers will help fuel the growing computational demands of artificial intelligence, as well as forming the backbone of an unhackable internet. But beyond the hype is the reality that quantum computers are still some ways from being commercially viable, as researchers continue to resolve issues like accuracy, size and how to build a superconducting electrical oscillators that are used in some quantum chips need to be cooled down to near-absolute zero temperatures, otherwise the problem of Quantum Device Lab at study co-author quantum entanglement, two particles become linked in a way so that whatever happens to one particle, it also immediately occurs to the other, no matter the distance. Having proven that a cryogenically based, long-distance quantum network is indeed possible, the team is now working to construct a 30-meter (98.4-foot) quantum link. See more over at ETH Zurich’s

Heavy Networking 511: A Wireless Upgrade Case Study

Today's Heavy Networking is all about wireless. Guest Bryan Ward, Lead Network Engineer at Dartmouth College, takes us through a campus-wide wireless upgrade that the institution is currently undertaking. We get nerdy about planning, infrastructure, cabling, and more, and dive into why the college is switching vendors.

BGP Hell Is Other People

If you configure a newsreader to alert you every time someone hijacks a BGP autonomous system (AS), it will probably go off at least once a week. The most recent one was on the first of April courtesy of Rostelecom. But they’re not the only one. They’re just the latest. The incidences of people redirecting BGP, either by accident or be design, are becoming more and more frequent. And as we rely more and more on things like cloud computing and online applications to do our daily work and live our lives, the impact of these hijacks is becoming more and more critical.

Professional-Grade Protocol

BGP isn’t the oldest thing on the Internet. RFC 1105 is the initial draft of Border Gateway Protocol. The version that we use today, BGP4, is documented in RFC 4271. It’s a protocol that has enjoyed a long history of revisions and a reviled history of making networking engineers’ lives difficult. But why is that? How can a routing protocol be so critical and yet obtuse?

My friend Marko Milivojevic famously stated in his CCIE training career that, “BGP isn’t a routing protocol. It’s a policy engine.” When you look at the decisions of Continue reading

How to Find a Networking Assistant

The networking assistant role is a major and important one in every business and organization. They are responsible for building, designing, implementing, and maintaining complex systems that keep employers in an organization productive. They work on computer networks that are the most critical part of every organization. They install, support, and maintain computer systems, including Intranet, Extranet, LAN (Local Area Networks), WAN (Wide Area Networks), phone system, network segments, and all other data communication systems.

Where to Find a Networking Assistant

When looking to hire a networking assistant for your business or organization, you need to spend time on some credible sites. Hiring a networking assistant shouldn’t stress you out, you only need to look in the right places to find the best for your business.

To connect with the right networking assistants, you need to check networking platforms where they spend time. Popular networking platforms or resources to find the best networking assistants include Cisco Support Community, Networking Forum, and AnandTech Forum. These are the top sites to find computer gurus for your business.

Start new forum threads to send recruitment messages and advertise your jobs to users on these platforms. Use the site as a resource to ask Continue reading

Remote User Access in the Era of COVID-19

The worldwide lockdown due to COVID-19 has given me an opportunity to reflect on many aspects of life and work. Nowadays I’m helping enable companies and non-profits for secure remote access work (i.e. not site-to-site VPN). I was looking into enterprise-grade solutions for secure remote users access to VPNs when I came across the Smart … Continue reading Remote User Access in the Era of COVID-19 →

Rolling With The Punches: Shifting Attack Tactics & Dropping Packets Faster & Cheaper At The Edge

On Cloudflare’s 8th birthday in 2017, we announced free unmetered DDoS Protection as part of all of our plans, regardless if you’re an independent blogger using WordPress on Cloudflare's Free plan or part of a large enterprise operating global network infrastructures. Our DDoS protection covers attack vectors on Layers 3-7; whether highly distributed and volumetric (rate-intensive) or small and sneaky. We protect over 26 million Internet properties, and at this scale, identifying small and sneaky DDoS attacks can be challenging, especially at L7. In this post, we discuss this challenge along with trends that we’ve seen, interesting DDoS attacks, and how we’ve responded to them so that you don’t have to worry.

Let’s Talk Trends

When analyzing attacks on the Cloudflare network, we’ve seen a steady decline in the proportion of L3/L4 DDoS attacks that exceed a rate of 30 Gbps in recent months. From September 2019 to March 2020, attacks peaking over 30 Gbps decreased by 82%, and in March 2020, more than 95% of all network-layer DDoS attacks peaked below 30 Gbps. Over the same time period, the average size of a DDoS attack has also steadily decreased by 53%, to just 11.88 Gbps. Yet, very large Continue reading

Video: Networks Are (Not) Secure

It’s amazing how many people still believe in Security Fairy (the mythical entity that makes your application magically secure), fueling the whole industry of security researchers who happily create excruciatingly detailed talks of how you can use whatever security oversight to wreak havoc (even when the limitations of a technology are clearly spelled out in an RFC).

In the Networks Are Not Secure (part of How Networks Really Work webinar) I described why we should never rely on network infrastructure to provide security, but have to implement it higher up in the application stack.

BiB093: Declare A K8s Stack With Spectro Cloud

Spectro Cloud is Kubernetes management. But...that's really oversimplifying it, especially with the hundreds of offerings that have something to with Kubernetes management or KaaS. If I'm being more precise, Spectro Cloud is about managing an entire infrastructure stack that's built around Kubernetes.

Dragonfly Brings Peer-to-Peer Image Sharing to Kubernetes

Dragonfly, a peer-to-peer image and file-sharing technology developed by Cloud Native Computing Foundation. The software provides a way to quickly distribute images across large cloud native deployments, eliminating the dependency on a single registry to distribute all the copies of an image. “Dragonfly is one of the backbone technologies for container platforms within Alibaba’s ecosystem, supporting billions of application deliveries each year, and in use by many enterprise customers around the world,” said Dragonfly in 2015, originally to ease file distribution. By 2017, when it was adopted to share containers within Kubernetes environments, it was being used by the Chinese cloud service to share 3.4PB each month. It was originally accepted into the OCI (Open Container Initiative). It can work with CNCF’s Prometheus and display them on a Helm can be used to install Dragonfly within a Kubernetes cluster. Project maintainers come from Alibaba, ByteDance, eBay, and Meitu. Overall it has 67 contributors from 21 organizations. It has been downloaded over 100,000 times from Docker Hub and has massed 6,000 GitHub stars. Learn more about Dragonfly, visit liggraphy from
