BFD is not a Fast Convergence mechanism !

BFD is not a fast convergence mechanism. BFD stands for Bidirectional Forwarding Detection. It is an important tool for the IP layer but there is a confusion in the network community about it.   BFD is a failure detection mechanism. Link and  node failures can be detected with it.   Without BFD, detection can be done at Layer […]

Feedback: Open Networking for Large-Scale Networks

Got this feedback from a network architect attending the Open Networking for Large-Scale Networks webinar:

I used the webinar when preparing for a meeting/discussion with a NOS SW-vendor. In the meeting, my knowledge was completely up-to-speed & I was on the level with the vendor in the discussion! :-)

Obviously, Russ White and Shawn Zandi did a great job based on their real-life hands-on experience (they use whitebox switches @ LinkedIn).

This blog covers how to install Cisco ASAv boxes for use with Vagrant. Cisco does not provide an ASAv Vagrant box on Vagrant cloud but it is possible to create a Vagrant boxes out of the ASAv VMware ova. As you will see it is a bit more involved but well worth the effort. This post assumes...

IDG Contributor Network: Is WAN Optimization Dead?

As an ever present staple of technology in the inventory of any major enterprise, WAN optimizers have begun to lose their luster.

Worth Reading: Web archiving and the importance of context

One of the most basic tenants of all data science is that data doesn’t exist in a vacuum, it is the result of a massive pipeline of explicit and implicit decisions, yet so much of the output of the data science world proceeds as if data can be cleanly separated from the contexts in which it is created. Nowhere is this more apparent than the world of web archiving. —Kalev Leetaru @ Forbes

Announcing the ultimate BGP how-to guide

The Border Gateway Protocol has become the most popular routing protocol in the data center. But for all its popularity, some consider BGP to be too complicated.

Moving Forward with Path Forward

Moving Forward with Path Forward

In February, I blogged about our first rotation of Path Forward returnships and the awesome people we’ve hired as a result of the program. As a refresher, Path Forward is a nonprofit organization that aims to empower people who’ve taken time away from their careers to focus on caregiving to return to the workforce.

Cloudflare started partnering with Path Forward this past year as a way to expand our talent pool to include the best and the brightest, regardless of any gaps in their career journeys. We truly believe in a diverse group of employees, and that includes those who can bring different perspectives from their time away from the workforce.

We’ve been lucky to have three amazing candidates go through the Path Forward program this time around across our People & Places, Solutions Engineering, and Marketing teams.
