Description:


Dave Ward, CTO & Chief Architect of the Service Provider Division at Cisco and Lauren Cooney, Senior Director of Software Market Strategy at Cisco join Packet Pushers hosts Greg Ferro and Ethan Banks for a discussion about software defined networking and the evolution of onePK & APIs.

Not to put too fine a point on it, we consider this to be an important show. A lot of what Dave and Lauren discuss on this program is future-thinking stuff, but with real meat on the bones. Dave isn’t just dreaming; he’s doing. Dave is right down in the guts of API development and IETF standards formation. He’s got a very good idea of where software defined networking should be taking the networking industry and how APIs can get us there.

What We Discuss

  • Cisco onePK – a software development toolkit providing a common data model, common object model, and common API across Cisco platforms running IOS, IOS-XR, and NX-OS.
  • OnePK is a foundation technology providing an abstraction layer. It enables programmatic interfaces.
  • The notion of a “network programming interface”.
  • How code you’ve written interacts with onePK agents, and ultimately with the end device.
  • How interaction with legacy SNMP and onePK is different.
  • What a “full duplex” interface is in the context of network programmability, and why it’s really, really important.
  • It’s not just about logs & events when it comes to our devices telling us things. It’s also about topology discovery, device capabilities, state, etc.
  • Where are we at with standardization of APIs? That’s going to drive SDN & network programmability further along if there’s industry agreement of baseline functionality.
  • IETF is working on IRS: Interfaces to the Routing System.
  • Why OpenFlow is limiting in the long-term vision of network programmability.
  • The CLI isn’t the magic. Getting the job done quickly and correctly is.
  • Why building an ecosystem around apps that can program the network is key.
  • The five modules Dave is working on to enable third parties to integrate with a variety of underlying network services.
  • The API layer cake: published APIs at the device, virtualization, and orchestration layers.
  • An emerging open ecosystem that drives API development.

Quotes

  • “Things don’t begin and end with OpenFlow by any stretch of the imagination.” – Dave Ward
  • “The whole goal is not just basic connectivity – it’s engineered connectivity.” – Dave Ward
  • “IT professionals need to be able to interact in a heterogeneous network in a standardized way and issue one command across the network to get something done.” – Dave Ward
