The (SDN) Shape of Things to Come

Coursera recently announced a course they have available on SDN – Software Defined Networking. The course description suggested a couple of YouTube videos as “suggested reading.” The first video was called “How SDN Will Shape Networking” by Nick McKeown of Stanford. Mr. McKeown makes many interesting points and by the end creates this outline for the changes that SDN portends for networking:

  1. Empower Network Owners/Operators
  • Customize networks to local needs
  • Eliminate unneeded features
  • Creation of virtual, isolated networks
  1. Increase the Pace of Innovation
  • Innovation at software speed
  • Standards (if any) will follow software deployment
  • Technology exchange with partners
  • Technology transfer from universities
  1. Diversify the Supply Chain
  • A variety of software suppliers
  • Vendors, homegrown, outsourced, open-source
  • Common hardware abstraction, with extensions
  1. Build a Robust Foundation
  • Standardized forwarding abstraction
  • Provable network properties at every step

This list presents the qualities of true technology disruption. As McKeown suggests, it is not unlike the massive change in computing that came with the microprocessor. He also cites research efforts that practically demonstrate the theory of SDN’s capability for the entire network to be described as a set of transfer functions – something very familiar to digital designers since the dawn of the computing age.

From the SevOne perspective, we tend to focus on SDN providing a robust foundation supporting provable network properties at every step. As the practice of SDN progresses, SevOne looks to simplify the admin’s role in proving reachability, identifying isolation and loops in the network, and in general proving the adage, “it’s not the networks’ fault.”
