The Napkin Dialogues: Nexus Programmability, Part II

July 9, 2014 at 8:48 am PST

When last we left our hero, he (that is, me, or I) was getting a crash course in Nexus programmability and trying to understand what all of this stuff meant. I had plied Jim* with beer in order to get him to explain to me – using the available napkins in the bar – what the technology was, what it meant, and why I should care. Read More »

The Napkin Dialogues: Nexus Programmability, Part I

June 30, 2014 at 12:08 pm PST

I know that I take a different approach to learning new things than most people. At least, I know my approach is different than the way people present them. The good news is that when I get something, I really get it. However, when looking at the juggernaut that is “Software-Defined X,” or even “programmability,” I know that I’m still a long, long way away from feeling like I have a handle on it.

When I wrote the previous blog post on some of the key “Open” terms were in programmability, I was overjoyed to find out that there were a few people who also had difficulty getting a grip on this too.

In other words, I’m not alone!

There is still a bewildering amount of information that I still need to learn, however, and it seems to me that if I resonated with a few people about these high-level topics, there are probably a few more who are curious about what lies beneath as well. Fortunately I work for a company (and with a lot of people) who have been willing to help me. Read More »

Part 2 – Virtualized Services in an EPN World?

In part one of this series Gina covered the basic definition of an Evolved Programmable Network or EPN and its linkage to the Cisco Evolved Services Platform (ESP).   Figure 1 offers a quick visual recap.

Cisco Evolved Programmable Network: The Beginning of a New Era in SP Networking

June 3, 2014 at 2:26 pm PST

ginaWritten By Gina Nienaber, Marketing Manager, SP Product and Solutions Marketing

This is the first blog out of a series of three covering  “What is the Evolved Programmable Network (EPN) Era and Why Evolved Programmable Network (EPN) Now?”

Those of us who have been around in the industry for a few decades will remember the first arrival of the “big bad wolf” that tried to blow down the service provider’s house. This wolf presented itself in the form of the commoditization of IP services and high traffic growth rates that limited service provider profitability options forcing them to move away from dedicated TDM-based networks that supported a single video, voice, data, or mobile service. Service Providers partnered with Cisco (and others) to build more scalable and lower costs converged IP Next Generation Networks (IP NGNs) and entered the IP NGN era. In doing so, a new wave of innovation and service revenues followed.

Until of course, “the big bad wolf” arrived on the scene again, also known as “exponential traffic growth, especially in mobile video, and this time he brought his friend along for the ride -- the Internet of Everything (IoE).  Cisco VNI predicts IP Traffic alone will grow 300 percent to 1.4 zettabytes annually by 2017. Most of you are already experiencing the pains of exponential traffic growth and some of you believe, as we do, the next wave of dramatic Internet growth will come through the confluence of people, process, data, and things — or the IoE! And IoE predictions are off the charts as well.  Cisco estimates that 99.4 percent of physical objects in the world are still unconnected. With only about 10 billion of the 1.5 trillion things currently connected globally, there is vast potential to connect the unconnected via the IoE.

When you combine exponential traffic growth with IoE impact on the horizon what do service providers get?  You guessed it -- cost and network complexity are rising at a faster rate than revenue. In order to deal with these challenges, (I would rather call them opportunities), network transformation is not optional, but essential for the next wave of growth and propriety.

This might also be a good time to mention the major innovations in cloud and virtualization technologies such as SDN and NFV are allowing for new agile competitors to enter into the market and are challenging traditional providers for their revenue streams by changing the service delivery game and giving the customer control over their service instantiation with consumption based business models.  If you would like to review a quick snapshot of the challenges providers are facing today see the Cisco EPN At-A-Glance.

Are you convinced we need to move from the IP NGN Era to the EPN Era Yet?  If not keep reading -- you will be.

Thoughts on #OpenStack and Software-Defined Storage

May 14, 2014 at 6:18 am PST

This week has been the semi-annual OpenStack Summit in Atlanta, GA. In a rare occurrence I’ve been able to be here as an attendee, which has given me wide insight into a world of Open Source development I rarely get to see outside of some interpersonal conversations with DevOps people. (If you’re not sure what OpenStack is, or what the difference is between it and OpenFlow, OpenDaylight, etc., you may want to read an earlier blog I wrote that explains it in plain English).

On the first day of the conference there was an “Ask the Experts” session based upon storage. Since i’ve been trying to work my way into this world of Programmability via my experience with storage and storage networking, I figured it would be an excellent place to start. Also, it was the first session of the conference.

During the course of the Q&A, John Griffith, the Program Technical Lead (PTL) of the Cinder project (Cinder is the name of the core project within OpenStack that deals with block storage) happened to mention that he believed that Cinder represented software-defined storage as a practical application of the concept.

I’m afraid I have to respectfully disagree. At least, I would hesitate to give it that kind of association yet. Read More »
