So, if you are a networking geek of any sort, you should be listening to PacketPushers--for both the education and the sheer entertainment value. This year, we tried something a little different with the PacketPushers team and had them join us onsite at CiscoLive. Below are six of the podcasts they produced for us:

For the most part, my last post was concerned about what Cisco ONE was, so explore a little more into the why. I am going to assume you read my last post, so let’s dig in. One of the fundamental concepts behind ONE is illustrated below--the idea of exposing the network in a highly granular way and emphasizing the ability to not only exert programmatic control over switch behavior, but the ability of the network to present interesting and useful information back up to the applications.

The onePK announcement Ric describes in the previous blog entry is game changing. It also intersects a trend which has gone fairly unnoticed in the networking standards areas. The importance of new standards is declining relative to advances in software and hardware. Read More »

There’s an incredible amount of hype and excitement these days around Software Defined Networking (SDN), which promises to herald in a new age of flexibility, business agility and automation to our existing data center and campus networks. Since there are very few, if any, SDN networks in production environments today, though, we know there are a lot of implementation details to work out before the industry achieves the lofty benefits of network programmability. Cisco opened its kimono this week on its strategy around programmable networks (an even broader concept than what we believe the traditional definition of SDN is), called Cisco Open Network Environment. (Get Omar’s take on Cisco ONE).
If you are like a lot of people, you might think that SDN is synonymous with OpenFlow, the leading standards-based approach for SDN today. However, we are already seeing folks across the industry extending the SDN vision beyond what OpenFlow is currently envisioned to do, so we think the definition of SDN will probably evolve over the next year or so to include additional programming models and protocols. Cisco ONE, for example, includes three approaches to network programmability: 1) our own onePK set of API’s to Cisco network operation systems and devices, 2) a portfolio of agents and controllers that will support OpenFlow, among other things, and 3) our Nexus 1000V-based portfolio for building virtual network overlays.
