There's been a lot of hullaboo in the last few years about the current cycle of disruption in IT:  Public Cloud, Private Cloud, SDN, DevOps, Everything-as-a-Service… the list goes on and on and every vertical, every field, and every niche is feeling the churn.  Every day there is no shortage of opinions "for" and "against" something in tech that is emerging, in decline, or re-emerging.  There is one aspect to all of it though that is largely ignored:  "The Short 't'." Every System in Summary Figure 1. A summary of any given system. Let's have a look at Figure 1.  It represents any given system:  A car, an MP3 player, a network, or a cloud-service.  Policy-Set "1" in implementation consists of some input state, configured or ephemeral, that allows the consumer of this system (be it human or another system) to express to the system some desired behavior or outcome th...

Is an SDN App Store Viable?

When it comes to API frameworks, there seems to be a Field-of-Dreams-esque view that If you build it, they will come. And as our industry dives headfirst into SDN waters, there will be people who advocate the proliferation of developer programs under the premise that networking needs an App Store. The question these people need to be asking is whether an SDN App Store is actually a strategically viable end state. Before I get into whether the networking industry can support an app store, I need to outline the strategy behind these developer programs. All developer programs are e... (more)

A Cisco-Insieme primer: What is application-centric infrastructure

With the launch of Cisco’s software-defined networking startup Insieme expected tomorrow, our industry is about to hear a lot about “application-centric” everything. So what does “application-centric infrastructure” mean? First, some basics: Networking is about connecting computing devices and systems so they can share data. Networking infrastructures are built with a combination of hardware such as gateways, routers, and switches that manage the movement of the data as well as software applications that enable you to do things like access the Inter...

2013 in Review: The Stories That Weren’t

From a news perspective, a year is defined by the stories that make headlines. But markets are frequently moved more by subtext than overt story. Its sometimes the less sexy and more subtle happenings at the fringe of media interest that determine how industries will evolve and ultimately who will win and lose. This past year was certainly the year of software-defined networking, but what important supporting bits played out just out of the limelight? The Launch. Given the amount of industry build-up, including rumors, a couple of head fakes, at least one aborted launch, and a ... (more)

SDN: Capability or Context?

Why is it that the definition of SDN continues to get debated? I think the definition of SDN remains a bit squishy. And while I am not entirely certain that it matters (people shouldn’t be buying SDN; they should be building networks), it is an interesting phenomenon, and understanding it better could help with the education process. When most people talk about what SDN is, they tend to fall into two camps: principles and protocols. You will frequently hear SDN described as the separation of control and forwarding planes. You probably hear people talking about SDN needing to be “... (more)
