Network programmability means democracy, means freedom, freedom to program across all layers and entities, software or hardware – depending on your needs. Is SDN required to have network programmability? Not at all. Does the SDN architecture leverage network programmability? Yes, of course. So, why do many people equate network programmability and SDN?

I admit it. I’ve grown weary of the debate about whether SDN includes network programmability or whether or not SDN can only be accomplished through NfV, or the relative merits of control plane / dataplane separation. I will leave those debates to others more focused on the technology itself. Personally, I have been more fascinated with what I see as the new business opportunities emerging around SDN.
Certainly there is a raft of opportunities for start-up companies in the controller space or in the virtualization of various networking functions. Many innovative new companies are re-examining existing network functions within the SDN paradigm; that will lead to some potentially new and useful approaches that may be cheaper/easier/faster than current designs. No doubt many customers will see value in these new ways of doing things, and everybody will benefit.
But that’s not what I find fascinating about SDN. What I am starting to see are ideas that are completely out of the box, and would likely not be thought of by typical network technologists working alone. Let me discuss a few categories of things I have seen possible with the emerging technologies.
The Network as a Compute Resource

Cisco Live is here! It’s a great opportunity for you to discover some really exciting technology solutions at our Cisco ONE: Cisco Intelligent Programmable Network booth featuring a few of our latest innovations.
Onsite you will be able to see and ask your questions at live demos featuring applications and services developed with One Programmable Kit (onePK), Openflow and the eXtensible Network Controller. In addition, we have demos devoted to IPv6, routing, service discovery and network design simulation -- all things meant to make your network simpler and smarter.
There are also some great partner demos including our friends from SAP, Citrix, Glue Networks, Pramacom, Radware, and Starview who are showing some really cool apps that use the Cisco ONE APIs. Read More »
Cisco’s One Platform Kit (onePK) is a fantastic toolkit for building custom applications that interact with your Cisco routers and switches. Using onePK, you can build automation directly into the network and extend all sorts of functionality using Cisco devices. The first in a three-part blog series, this article will introduce onePK to the reader, explain what it is, how it can be useful, and will show how to configure onePK on a router. The second and third installments will walk the reader through a simple security-relevant application using the C API. Important to note is that we’ll be covering the 0.6.0 version of onePK features and service sets. At the time of this writing, the toolkit is still in Controlled Availability and as such, is still in active development, and the API could change before it is released into General Availability. However, even in the face of API evolutionism, this article will provide you with a solid jumping-off point for your plunge into the wondrous world of onePK.
OK, Just What is onePK?
OnePK is a Cisco IOS Software feature and a set of programming libraries enabling an application programmer to build powerful applications that tightly integrate and interact with Cisco devices. onePK is available to you via a well-documented and unified API, currently offered in C and Java with Python in active development. It is currently in pre-release and is available only on request. Details on how to obtain onePK are provided below. Read More »
What do you get when you take Cisco’s best-selling campus access switch line, double almost everything (including port density in-stack, stacking bandwidth, buffers and CPU), then make it more secure and simpler to use, all with power-saving capabilities that possibly make it the “greenest” access switch in the industry?
You get a GameChanger
This is exactly what Cisco announced yesterday (June 4th) at our annual Partner Summit event. Cisco is introducing the next generation of its wildly successful Catalyst 2K switches with the new Catalyst 2960-X series of stackable Gigabit Ethernet access switches. Read More »
