In this episode Rick and Melchior discuss with Dino Farinacci how LISP can help solve internet challenges.
We touch on FIB scaling, mobility, IPv4 runout, COVID-19 and digital voting apps, blockchain and quantum internet.
Clustering is a way to make sense of the data by grouping similar values into a group. There are many ways to achieve that and in this post we will be looking at one of the way based on spectral method. Spectral clustering provides a starting point to understand graphs with many nodes by clustering them into 2 or more clusters. This clustering technique can also be applied for analyzing general data. This technique is based on Linear algebra and Graph theory.
We will start with a very brief introduction of the prerequisite for the sake of completeness and one can skip the prerequisite topics if they already have the familiarity.
One way to interpret when we multiply a vector a matrix is that a matrix transforms the vector. For example: below is a vector \(\begin{pmatrix} 2\\1 \end{pmatrix}\)
we apply a transformation by multiplying the above vector to a matrix
\[\begin{pmatrix} -1 & 3 \\ 2 & -2 \end{pmatrix}\]The resultant vector \(\begin{pmatrix} 1\\2 \end{pmatrix}\) is in orange after transformation.
you can see how the vector changed its direction after the transformation. Now in case of Eigenvectors, which are special kinds of Continue reading
In 2020 our automation skills may be the only thing that does travel! What I mean is that the automation skills being evangelized by so many in the networking community (Kirk Byers, David Bombal, Nick Russo, Jason Edelman and the Network to Code team, Hank Preston and Cisco DevNet and many more ....) will serve READ MORE

Should the network be dumb or smart? Network vendors have recently focused on making the network as smart as possible because there is a definite feeling that dumb networks are quickly becoming a commodity—and it’s hard to see where and how steep profit margins can be maintained in a commodifying market. Software vendors, on the other hand, have been encroaching on the network space by “building in” overlay network capabilities, especially in virtualization products. VMWare and Docker come immediately to mind; both are either able to, or working towards, running on a plain IP fabric, reducing the number of services provided by the network to a minimum level (of course, I’d have a lot more confidence in these overlay systems if they were a lot smarter about routing … but I’ll leave that alone for the moment).
How can this question be answered? One way is to think through what sorts of things need to be done in processing packets, and then think through where it makes most sense to do those things. Another way is to measure the accuracy or speed at which some of these “packet processing things” can be done so you can decide in a more Continue reading
Today's Network Break analyzes multi-cloud networking announcements from Fortinet and Arrcus, discusses additional venture funding for ASIC-maker Innovium, looks at more consolidation in the SD-WAN market, and debates whether "Internet" should be capitalized.

Creating a miracle: Residents of rural British Columbia, Canada, are pushing for better Internet access, with one resident saying getting access to good connectivity is like “hoping for a miracle,” the CBC reports. Local government leaders are working with community leaders and businesses to improve Internet services. Local leaders are researching options to establish a broadband Internet service in Clearwater, British Columbia, including the possibility of building new mobile towers.
Building their own: Meanwhile, a few hundred miles south in Klamath, California, Yurok tribal officials have announced a new project that they hope will significantly boost Internet speeds and expand coverage on their reservation, KRCR News reports. The$2.1 million project is funded by the U.S. Coronavirus Aid, Relief, and Economic Security Act. One of the goals is to better allow students to participate in distance learning.
No distance learning for you: In a related story, a study from Future Ready Schools finds that 16.9 million U.S. students lack home Internet access, Education Dive says. In addition, 3.6 million U.S. households lack a computer, impacting 7.3 million students, according to the study. About a third of Native American, Latino, and African-American students in the Continue reading
We launched Cloudflare Workers® in 2017 with the goal of building the development platform that we wished we had. We want to enable developers to build great software while Cloudflare manages the overhead of configuring and maintaining the infrastructure. Workers is with you from the first line of code, to the first application, all the way to a globally scaled product. By making our Edge network programmable and providing servers in 200+ locations around the world, we offer you the power to execute on even the biggest ideas.
Behind the scenes at Cloudflare, we’ve been steadily working towards making development on the Edge even more powerful and flexible. Today, we are excited to announce the next phase of this with the launch of our new platform, Workers Unbound, without restrictive CPU limits in a private beta (sign up for details here).
Workers Unbound is like our classic Cloudflare Workers (now referred to as Workers Bundled), but for applications that need longer execution times. We are extending our CPU limits to allow customers to bring all of their workloads onto Workers, no matter how intensive. It eliminates the choice Continue reading
It seems like ages ago that we blocked out time in our schedules to fly to technical conferences and immerse ourselves with great people and content for an entire week.
In reality, it’s only been a few months but 2020 has made it seem like a lifetime.
However, those of us in tech are quick to adapt and virtual conferences are now a thing.
For the fixed wireless industry, in-person conferences are critical because most of the attendees are entrepreneurs.
For a small business owner in tech, going to a show is one of the best ways to evaluate content and business opportunities needed to stay competitive in a short amount of time.
Thankfully, due to some amazing effort and collaboration in the WISP industry led by Preseem and supported by WISPA, we are about to kick off the first virtual conference for the fixed wireless industry on July 28th, 2020.
An enormous amount of work has gone into planning and preparation to replicate the experience of an in-person technical conference as much as possible.
Kick off the registration process by visiting: https://wispvirtualsummit2020. Continue reading
Cloudflare Workers® is one of the largest, most widely used edge computing platforms. We announced Cloudflare Workers nearly three years ago and it's been generally available for the last two years. Over that time, we've seen hundreds of thousands of developers write tens of millions of lines of code that now run across Cloudflare's network.
Just last quarter, 20,000 developers deployed for the first time a new application using Cloudflare Workers. More than 10% of all requests flowing through our network today use Cloudflare Workers. And, among our largest customers, approximately 20% are adopting Cloudflare Workers as part of their deployments. It's been incredible to watch the platform grow.
Over the course of the coming week, which we’re calling Serverless Week, we're going to be announcing a series of enhancements to the Cloudflare Workers platform to allow you to build much more complicated applications, lower your serverless computing bills, make your applications even faster, and prove that the Workers platform is secure to its core.
Before the week begins, I wanted to step back and talk a bit about what we've learned about edge computing over the course of the last three years. When we Continue reading
Video conferencing is the best way to communicate with others if you are working remotely or you are a part of a global team. However, now it has become a basic necessity. We have all heard of Zoom, and this year, it has become very popular.
We see people celebrating birthdays and having cocktail parties on Zoom now. People now consider Zoom parties to be the most convenient and safe way of staying in touch with one another. It has become the new norm of networking online. However, creating Zoom parties requires a bit of learning, especially if this is your first time hosting a virtual party.
In this article we will talk about the steps to set up a Zoom party, especially for those who have not yet discovered how to do so.
First things first, use a laptop. Zoom has a mobile application too, but attending a virtual zoom party can be hard as you will have to keep holding the phone, which will soon become draining. Other than that, attending a Zoom party on a laptop is a lot more fun, you can see all the faces and eat Continue reading
Blame it on the webinar yesterday… I’m late again.
However, there have been multiple reported attempts to exploit the transfer market as part of malicious operations — such as the hijacking of dormant address space and spamming — which, judging by exchanges between operators in mailing Continue reading
Hey there! I am Els (short form for Elspeth) and I am the Field Marketing and Events Manager for APAC. I am responsible for building brand awareness and supporting our lovely sales team in acquiring new logos across APAC.
I was inspired to write about my first year in Cloudflare, because John, our CTO, encouraged more women to write for our Cloudflare blog after reviewing our blogging statistics and found out that more men than women blog for Cloudflare. I jumped at the chance because I thought this is a great way to share many side stories as people might not know about how it feels to work in Cloudflare.
Before I continue, I must mention that I really wanted to join Cloudflare after reading our co-founder Michelle’s reply on Quora regarding "What is it like to work in Cloudflare?." Michelle’s answer as follows:
“my answer is 'adult-like.' While we haven’t adopted this as our official company-wide mantra, I like the simplicity of that answer. People work hard, but go home at the end of the day. People care about their work and want to do a great job. When someone does a good job, Continue reading
