Healthy Paranoia Show 20: SDN – Heretic of Security

The known universe has been ruled by the monolithic network device.

In this time, the most precious substance in the Universe is the  ASIC.

The ASIC extends life.

The ASIC expands consciousness.

The ASIC is vital, it provides the ability to fold space. That is, travel to any part of the network.

The ASIC exists in Silicon Valley. A desolate part of the planet with vast freeways.

There is a prophecy: that merchant silicon and network virtualization will come, a messiah will lead engineers to true freedom, called SDN.

SDN is the little-death that will bring total obliteration.

Welcome all fremen (and frewomen) to the planet of Healthy Paranoia with your Bene Gesserit host, Mrs. Y. On this episode, we’ll be learning the weirding way of Software Defined Networking (SDN). Joining us is Mentat Ivan Pepelnjak from House IPspace, Space Navigator Brad Hedlund from House VMware, Baron Brent Salisbury from House Open Daylight, Ethan Banks, Supreme Bashar and Greg Ferro, Emperor of House Packetpushers. What is this enigma known as SDN? Will it be the Kwisatz Haderach of Networking? According to the Open Networking Foundation:

Software-Defined Networking (SDN) is an emerging architecture that is dynamic, manageable, cost-effective, and adaptable, making it ideal for the high-bandwidth, dynamic nature of today’s applications. This architecture decouples the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. The OpenFlow™ protocol is a foundational element for building SDN solutions.

In this episode we’ll cover:

  • SDN 101 for the uninitiated
  • Benefits and impact of SDN
  • Potential use-cases in security
  • How will the infrastructure change?
