Will Software Defined Networking Actually Happen?

As a writer for the IT media, conference speaker, and co-host of the Packet Pushers podcast, I cover emerging networking technologies often. The new tech that comes across my screen ranges in value from “I can’t believe that got funded,” to “Why has no one thought of this before?” and everything in between. As a big idea, software defined networking (SDN) seems to generate about that same range of responses from network engineers. Some networkers think that SDN is an extraordinary technology that’s going to change the world of IT. Others see SDN as yet another in a long string of quirky networking ideas that never gained acceptance. In fact, as I’ve read responses to my SDN-related content over the last few years, I believe that more folks are in that latter camp. SDN is a fad. SDN is a buzzword. SDN will go nowhere useful. SDN will eventually fail to have a universal impact.

I understand the cynicism. After all, for a long time, networking had lapsed in an innovation coma, with nothing especially exciting coming along to really shake things up. Yes, Ethernet’s gotten faster. And that BYOD thing got everyone excited a couple of years ago. But for the most part, we design, build, and operate networks the same way today that we did fifteen or more years ago. The core underlying protocols have grown up or had new knobs and levers added, but generally speaking, if a networker of the past fell out of a time warp and into a design project today, it wouldn’t take them too terribly long to catch up.

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 Joins China Mobile at Mobile Asia Expo (MAE)

Mobile is a fast-changing industry! Every year there are new devices, new technologies, and trends.

China is one of the fastest growing mobile markets in the world with:

  • 1.2 billion mobile connections and growing.
  • The number of 3G mobile telephone users reached 386 million in November 2013, a growth of 154 million over the same period of last year.
  • Smart phones in China reached 348 million units from January to October 2013
  • December 2013, China had 500 million mobile Internet users, a growth of 80.09 million compared with that at the end of 2012

The number one mobile operator in China is China Mobile with an estimated 781M subscribers as of Q1 2014. To handle such a large customer base China Mobile has become an industry leader with their vision of Network Functions Virtualization (NFV) in the quest to control operational costs and create the network elasticity new services creation.

Just as Cisco did in the China Mobile Booth at MWC 2014, Cisco is joining China Mobile at Mobile Asia Expo (MAE) in their “Network Function Virtualization Demonstration” located in the China Mobile

How Virtualization Is Changing Software Licensing for the Data Center

Erich Latchford

In the days before data centers were virtualized, the licensing model for operating systems and application software was simple: 1 server = 1 license. But this model doesn’t work in an environment where a single physical server can host multiple virtual servers.

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.
