For me, even though I am mostly a hardware geek, one of the coolest parts of the Cisco ONE launch at CiscoLive was the introduction of onePK. We see onePK as an core enabling technology that will have some cool stuff down the road.
So, one of the more common questions I get is about the relationship between onePK and other technologies related to network programmability such as OpenFlow (OF). Many folks mistakenly view this as an either/or choice. To be honest, when I first heard about onePK, I thought it was OpenFlow on steroids too; however, I had some fine folks from NOSTG educate me on the difference between the two. They are, in fact, complementary and for many customer scenarios, we expect them to be used in concert. Take a look at the pic below, which shows how these technologies map against the multi-layer model we introduced with Cisco ONE:
As you can see, onePK gives developers comprehensive, granular programmatic access to Cisco infrastructure through a broad set of APIs. One the other hand, protocols such as OpenFlow concern themselves with communications and control amongst the different layers—in OpenFlow’s case, between the control plane and the forwarding plane. Some folks have referred to onePK as a “northbound” interface and protocols such as OpenFlow as “southbound” interfaces. While that might be helpful to understand the difference between the two technologies, I don’t think that this is a strictly accurate description. For one thing, developers can use onePK to directly interact with the hardware. Second, our support for other protocols such as OpenFlow is delivered through agents that are built using onePK.
That last part, about the agent support is actually pretty cool. We can create agents to provide support for whatever new protocols come down the pike by building them upon onePK. This allows flexibility and future-proofing while still maintaining a common underlying infrastructure for consistency and coherency.
For instance, we are delivering our experimental OF support by building it atop the onePK infrastructure. For customers this is a key point, they are not locked into a single approach—they can concurrently use native onePK access, protocol-based access, or traditional access (aka run in hybrid mode) as their needs dictate. Because we are building agents atop onePK, you don’t have to forgo any of the sophistication of the underlying infrastructure. For example, with the forthcoming agent for the ASR9K, we expect to have industry leading performance because of the level of integration between the OF agents and the underlying hardware made possible by onePK.
In closing, you can see how extensible our programmatic support is with the ability to use onePK natively or to support technologies and protocols as they are developed and released. This gives customers a remarkable level of flexibility, extensibility and risk mitigation.

If I have said it once, I have said it at least a thousand times. No figure of speech here, completely one hundred percent literal. What have I said? “If you can do it in UCS Manager GUI, you can do it in UCS Manager API!” Whatever “it” is.
When do I say this? Whenever I talk about the UCS Manager to customers or coworkers, there is almost always the question, “Can this be done via the API?” To which I always reply “If you can do it in the GUI you can do it in the API.” Not sure if that is grammatically correct, but my point is made. That is the power and the ease of the UCS XML API.
The UCS Manager graphical interface is built on the XML API. When developing a script and you’re not sure how to do the action, what the call is, what the correct parameters are, etc… Just look at how the UCS Manager does it and you’re good. How do you look at how UCS Manager does it? Use Wireshark or some other packet capture tool and see what’s going on, what is getting passed from the UCS Manager client to UCS Manager. Done, no secrets, no convolution, no obfuscation.

Wow, there’s been a lot of news in the SDN and virtual networking space in the last week or so! VMware acquiring Nicira, and Oracle acquiring Xsigo are testimony to how important virtual overlay networks and virtual switching infrastructure has become for data center vendors, and how integral they are to each company’s strategy. Speaking of our own Nexus 1000V-based virtual networks, last week I provided an overview and some new resources on Virtual Extensible LANs (VXLAN) for Nexus 1000V virtual switches. That turned out to be quite a popular post, so I’m following up this week on another fundamental component of Nexus 1000V-based virtual networks, vPath, the secret sauce that allows us to deploy virtual network services in the data center.
What is vPath? Well, if VXLANs can set up secure tunnels over a shared, multi-tenant virtual network, vPath is a feature of the Nexus 1000V virtual switch that can redirect traffic to virtual application services before the switch sends the packets down into the virtual machine. Very important stuff, but how does it do that? I find that my blog posts are more popular the less I type, and the more I embed cool TechWiseTV videos that illustrate the concept, so I’m dusting off this classic from the TWTV team on just how vPath does that with our Virtual Security Gateway (VSG). Take it away Robb…
But wait, there’s more… Read More »

At Cisco live last month I spent several days talking to a lot of customers about all the new enhancements to our Nexus 1000V portfolio, especially the programmable virtual network overlays that are part of the Cisco ONE framework for SDN/network programmability. While the Nexus 1000V-based virtual networks are really gaining traction (6,000+ Nexus 1000V virtual switch customers to date), I still found a lot of folks weren’t all that familiar with the concept of VXLAN, and why they are so important to building scalable cloud networks and multi-tenant data centers.
Well, not to fear, VXLAN MAN is here! Well, not really, but we have just released a great new fundamentals video on VXLAN from the creative geniuses at Techwise TV (Thanks to @JimmyRay_Purser and @robbboyd!). We’ve gotten great reviews on this so far, and I know the guys really had a fun time in creating this one.
But wait, there’s more… Read More »

As the London 2012 Olympics kicks off today, the 100m sprint event will be one I’ll definitely be watching on TV. And with Cisco as the Official Network Infrastructure Supporter for London 2012 - an event that is generating huge excitement here in Cisco UK and Ireland as well as Cisco globally, let me use an Olympics analogy to illustrate how Cisco Services helps you accelerate deployment of our recently announced Cisco Intelligent Automation for Cloud Starter Edition, described in excellent detail by my good colleagues Wayne Green and Jason Schroedl.
The Acceleration is in the Preparation
While the 100m sprint will (hopefully!) be won in a sub-10 second time, without doubt the winner will have taken much, much longer in preparation. Like all the Olympic sports, the 100 sprint is an event where the participants will have prepared for several – if not many – years. They are at the top of their game. As I learned recently in a seminar at our Cisco Scotland office with Olympic medal winners Roger Black and Steve Backley, what is maybe not so visible is that they all have an extensive team behind them, helping them deliver that fantastic time. And despite their own expertise, commitment and talent, they will have called on specialist expertise – physios, expert trainers, even sports psychologists – to help them accelerate from those starting blocks and over that finishing line in record time. And for those competitors participating for the first time in such a major event, this background team will be all the more important in helping them develop their race plan.
So now onto cloud automation, and how Cisco Services can – in an analagous manner – help you accelerate from the starting block with Cisco Intelligent Automation for Cloud Starter Edition ….
