Automation Solution: Deploy BGP Routing with YANG Data Models
A while ago Ruben Tripiana tried to configure BGP on Cisco IOS using IETF YANG data models… and failed. In Spring 2019 Building Network Automation Solutions online course Chris Crook decided to deploy BGP routing on multiple platforms using YANG data models instead of configuration templates. Not only did he succeed, he also documented his work and the tools he used, and published the solution so you can replicate his efforts.
You can find many more network automation solutions created by the attendees of our automation course in solutions showcase.
Controlling Information Flow: NATS Subjects and Queues
Publish/subscribe messaging platforms like NATS allow us to build highly event-driven software systems, where we can build software to constantly listen for relevant messages and take action accordingly. This is what makes EDI projects like StackStorm (a project I’ve worked on and written about before) - and others like it- so powerful. Another advantage of pub/sub systems is that publishers don’t have to know or care if anyone is listening.Controlling Information Flow: NATS Subjects and Queues

NSX-T 2.5 What is new for Kubernetes
NSX-T 2.5 was released last week and now we also have the new NSX Container Plugin 2.5 on the market…. VMworld US 2019 is also over with announcements of huge innovations like NSX Intelligence, enhanced security, and improved operability and observability. You can find more information here! I would like to take this opportunity to specifically highlight the new containers capabilities we had been working on for this release.
What is new in NSX Container plugin (NCP)
Simplified UI (Policy API) support
With the introduction of the new intent-based Policy API and corresponding Simplified UI, administrators have seen that objects created by NCP for Kubernetes are not visible in the new UI. Instead they had to go to the Advanced Networking & Security tab that corresponds to the old imperative APIs. Furthermore, all related objects like T0, IP Block, IP Pool had to be created using the Advanced Networking & Security tab. I am happy to announce that from NCP 2.5+ we have a parameter in the NCP configmap (ncp.ini) policy_nsxapi that can be set to True. In that case, NCP will start calling the new intent-based API and all objects will be visible in the simplified UI. Continue reading

NSX-T Data Center and EUC Design Guide Release
When it comes to VMware NSX, support for VMware Horizon deployments have been a staple ask every release. NSX compliments Horizon deployments tremendously by:
- Helping to provide the networking for the Horizon components
- Identity and firewalling security for VDI and RDSH desktops
- Endpoint protection
- Load balancing
Earlier this year, NSX-T Data Center 2.4 was released which brought identity firewalling, endpoint protection, and other necessary features for customers to consume equivalent to NSX Data Center for vSphere. The release of NSX-T Data Center 2.5 takes those features and provides even further scale enhancements to support small, medium, and the largest Horizon deployments.
NSX-T Data Center and EUC Design Guide
The NSX-T and EUC Design Guide takes information provided in the VMware Horizon Reference Architecture and the VMware NSX-T Reference Design Guide, and brings the two platforms together into a single solution.
Use Cases and What’s Covered
Let’s take a look at what all is covered and the use cases that NSX-T Data Center has for Horizon deployments:
Horizon Pod Alignment
NSX-T Data Center 2.5 supports massive scale that can cover an entire Horizon Pod scale, and more in some cases. This design guide Continue reading

In Colombia: Latin American Summit on Community Networks
The University of Cundinamarca will host the Second Latin American Summit of Community Networks September 24-28. The event is organized by the Community Networks Special Interest Group, the Fusa Libre Collective, and the Colombia Chapter, with backing from the Internet Society.
The Summit, which will include representatives of 24 organizations that operate community networks in different countries, is meant to be a resource for the region. On the first day there will be 12 presentations that will share experiences from projects developed in countries such as Argentina, Colombia, Ecuador, and Mexico.
During the rest of the Summit, attendees will explore topics that will help strengthen their projects and enhance their development. The topics addressed in these working sessions have been defined collaboratively: gender-related issues, regulatory frameworks, local content, methodological strategies for community work, and actions for the promotion and deployment of new community networks. It could not be otherwise in a community where collaboration has stood out. In addition, attendees can share their experiences and best practices.
Although many people are familiar with the term “community networks,” their collaborative nature can be a surprise to those who are learning about how they function. Seeing people working together to plan, Continue reading

Inside the Web Browser’s Performance API
Building a beautiful, feature-rich website is easier than ever before. Not long ago, you’d have to fire up a text editor and hand-craft a lot of HTML, CSS, and JavaScript. Today, you can use WYSIWYG tools and third-party libraries that make development much simpler. The flip side of this is that it can be hard to see everything that’s going into your website — and the performance can suffer.
The good news is that modern web browsers expose lots of performance data that can help you understand how your web page performs. With the launch of Browser Insights today, we can analyze the performance from the perspective of the web browser and what the end user actually experiences. In this post, we’ll dive into how we think about performance and utilize the timing APIs in the web browser.
How web browsers measure performance
In the old days, the only way for a developer to profile performance was to intercept requests and measure the time from the beginning of the page load until the end of the load event.
Today, we can use Web APIs that are supported by modern browsers. This is part of the web standard called the Performance Continue reading
Introducing Browser Insights
Speed matters. We know that when your website or app gets faster, users have a better experience and you get more conversions and more revenue. At Cloudflare, we spend our days obsessing about speed and building new features to squeeze out as much performance as possible.
But to improve speed, you first need to measure it. That’s why we’re launching Browser Insights: a new tool that measures the performance of your website from the perspective of your users. Browser Insights lets you dive in to understand where, when, and why web pages are slow. And you can enable it today, for free, with one click.
Why did we build Browser Insights?
Let’s say you run an e-commerce site, and you want to make your conversion rates better. You’ve noticed that there’s a lot of traffic from visitors in Peru, but they have worse conversion than users in North America. Maybe you theorize that it takes a long time to load your checkout page, which causes customers to drop off before checking out. How would you verify that this is happening?
There are a few ways you could do this: you could check your server logs to look at timing Continue reading
