A Simple Virtual Network based on proxy ARP and Policy Based Routing
Introduction Choosing a Virtual networking to connect VMs or Containers across Hosts is always a complicated decision. Most of us would have found the virtual networking on a single VM/Container Host to be very simple, easy to implement and debug. Just plug the VM/Container to a bridge and your are done. For access from the … Continue reading A Simple Virtual Network based on proxy ARP and Policy Based RoutingNetwork Break 234: Windows Adds A Linux Kernel; Cisco Announces An SD-WAN Colo Option

The Week in Internet News: Broadband Project to Nowhere
Dead end: ProPublica has a story about Kentucky’s $1.5 billion broadband expansion program, which the story calls an information highway to nowhere. The program is behind schedule and over budget, with the state’s IT chief directing money to other projects and partnering with commercial ISPs.
Broadband billions: Meanwhile, the U.S. Department of Agriculture says that bringing broadband to unserved areas of the country would generate $47 billion of new economic activity a year, according to a story at Talkbusiness.net. Broadband in rural areas would enable precision agriculture technologies, which allows high-tech crop management based on sensors and other connected data sources.
I can’t Google: Finally, our broadband access trifecta of stories concludes with a Cronkite News story about the lack of access in many U.S. tribal areas. “Just Google it” has become a bit of a joke among the Hopi tribe in Arizona because many areas don’t have Internet access.
The luxury of privacy: Consumer privacy online can’t be a luxury good that only the rich have access to, Google CEO Sundar Pichai said recently in an opinion piece at the New York Times. Speaking at a conference, Pichai also spoke in favor of privacy legislation Continue reading
Argo and the Cloudflare Global Private Backbone
Welcome to Speed Week! Each day this week, we’re going to talk about something Cloudflare is doing to make the Internet meaningfully faster for everyone.
Cloudflare has built a massive network of data centers in 180 cities in 75 countries. One way to think of Cloudflare is a global system to transport bits securely, quickly, and reliably from any point A to any other point B on the planet.
To make that a reality, we built Argo. Argo uses real-time global network information to route around brownouts, cable cuts, packet loss, and other problems on the Internet. Argo makes the network that Cloudflare relies on—the Internet—faster, more reliable, and more secure on every hop around the world.
We launched Argo two years ago, and it now carries over 22% of Cloudflare’s traffic. On an average day, Argo cuts the amount of time Internet users spend waiting for content by 112 years!
As Cloudflare and our traffic volumes have grown, it now makes sense to build our own private backbone to add further security, reliability, and speed to key connections between Cloudflare locations.
Today, we’re introducing the Cloudflare Global Private Backbone. It’s been in operation for a while now and links Continue reading
Automating Brownfield Environments (Using an 802.1x Example)
This is a guest blog post by Albert Siersema, senior network and cloud engineer at Mediacaster.nl. He’s always busy broadening his horizons and helping his customers in (re)designing and automating their infrastructure deployment and management.
This is the second post in a series focused primarily on brownfield automation principles using 802.1x deployments as an example (you might want to read part 1 first).
Before diving into the specifics of the next 802.1x automation phase, let’s take a step back and think about why we’re going through this effort. Automation is a wonderful tool, but it’s not a goal… and neither is 802.1x a goal - it’s just another tool that can help us realize business benefits like:

Every year, we celebrate Cloudflare’s birthday in September when we announce the products we’re releasing to help make the Internet better for everyone. We’re always building new and innovative products throughout the year, and having to pick five announcements for just one week of the year is always challenging. Last year we brought back Crypto Week where we shared new cryptography technologies we’re supporting and helping advance to help build a more secure Internet.
Today I’m thrilled to announce we are launching our first-ever Speed Week and we want to showcase some of the things that we’re obsessed with to make the Internet faster for everyone.
How much faster is faster?
When we built the software stack that runs our network, we knew that both security and speed are important to our customers, and they should never have to compromise one for the other. All of the products we’re announcing this week will help our customers have a better experience on the Internet with as much as a 50% improvement in page load times for websites, getting the most out of HTTP/2’s features (while only lifting a finger to click the button that enables them), finding the optimal route across Continue reading

Worth Reading: Nothing Fails Like Success
I hope I'm still allowed to quote a paragraph from someone else's article (thank you, EU, you did a great job). Here's what Jeffrey Zeldman wrote about startup business models:
A family buys a house they can’t afford. They can’t make their monthly mortgage payments, so they borrow money from the Mob. Now they’re in debt to the bank and the Mob, live in fear of losing their home, and must do whatever their creditors tell them to do.
Read the article and think about how it applies to unicorn-based networking technologies ;)

Introducing The Internet Society Accessibility Special Interest Group
An ordinary day on 9th April 2019 was turned in to an extraordinary one, as our efforts bore fruit and we finally succeeded in chartering the Internet Society Special Interest Group on Accessibility. The Internet Society Accessibility Special Interest Group or ISOC Accessibility SIG/ISOC A11y SIG is intended to serve persons with disabilities to ensure the Internet and digital domain is for everyone.
Over 1.3 billion people worldwide – about 15% of the world’s population – experience some form of disability. The Accessibility SIG, with a people-centric approach, is aimed at providing interested participants a platform to discuss the Internet-related accessibility issues faced by the people with disabilities and to try to find the solutions to those issues. It also aims to provide a collective voice to a community that the UN calls the world’s largest minority.
The SIG also represents a journey for all of us who are members and who are dedicated to creating equal access to the Internet for everyone regardless of disability. The journey at the Internet Society started with the establishment of the ISOC Disability and Special Needs Chapter in 2002. Along the way, many dedicated and tireless workers, like the late Cynthia Waddell Continue reading
