In the context of the Internet and BGP routing, DFZ – commonly known as Default Free Zone – refers to the collections of all the public IPv4 BGP prefixes without default route on the global Internet. Most of the time, you hear full-route or full-Internet-route terms which are the same with Default Free Zone term. Having all BGP routes, […]

Follow these best practices to avoid security pitfalls with your Internet of Things deployment.
A look at the evolution of a technology that's poised to make big waves in storage.
One of my ExpertExpress engagements focused on networking in a future private cloud that might be built using OpenStack. The customer planned to deploy multiple data centers, and I recommended that they do everything they can to make sure they don’t make them a single failure domain.
Next step: translate that requirement into OpenStack terms.

One of the (many) nice things about this is that you can potentially ‘compile’ your pipeline definition into an executable program that provides a functional simulation of a P4-based ASIC. Did I mention the tools for doing all of this are available as open source?
