Summary: An Innovative Infrastructure to Capture the Value of the Internet of Everything

The Internet of Everything (IoE) is no longer a prediction. It is reality. As I think about the infrastructure needed to truly capture its value, I immediately think the network needs to be:

  • Agile
  • Intelligent
  • Secure

Why are these qualities a necessity for a thriving programmable infrastructure? Simply, it will allow enterprises to be ready for today’s business needs and tomorrow’s new business models.

Business Insights 12 11 13

Organizations must be able to quickly, intelligently and securely leverage their infrastructure to keep pace with business transformation driven by emerging cloud and mobile technology.

Today’s world is dominated by what Gartner Vice President David Cearley calls the “four powerful forces: social, mobile, cloud and information.” An infrastructure must increasingly demonstrate it can add value to the business, by rapidly and securely rolling out new services, apps and capabilities in a connected world.

SDN Reflections on the London Gartner Data Center Conference – Part 2

The London Eye

The London Eye

Last week I started my SDN reflections on the London Gartner Data Center Conference, and I found I had quite a lot to discuss.

Last week I covered:

  • Do we need SDN?
  • SDN and the Gartner Hype Cycle
  • SDN Deployment Models

So here is the concluding part. This week I’ll cover:

  • Overlay-Based SDN — and the questionable assumptions being made by others in this area (good for Gartner for calling these out!)
  • The SDN Vendor Explosion Challenge,
  • The “Unspoken Costs” of SDN Deployment, and
  • The “How” of SDN is still missing.

I hope you find this useful and informative and as always, feel free to debate with me around my observations!

SDN: Cisco Domain Ten tells us it’s not (just) about the Network

September 26, 2013 at 3:30 pm PST

In my first SDN blog, I asserted that “Services” -- that is technical support, professional and consultancy services -- are the missing “S” in the SDN debate.  I’d now like to apply our Cisco Domain TenSM framework “in anger” :-) to examine in more detail the impacts that SDN may have on your IT services and operations.  While come of our competitors will only talk about the network switches and new device protocols,  l’ll show how it’s not just the network switches that you should be concerned with: your SDN and Cisco ONE journey could involve impacts across multiple “domains”.

As I bogged about Cisco Domain Ten this past year, I’ve positioned it as a mechanism to help you on your data center journey.  Let me now extend that use -- SDN after all is more than just a data center technology play.  My experience with Cisco Domain Ten over the past year has helped me realize that it is, in fact, an excellent framework for considering impacts to more general IT services, and not just to  the data center .  I’ll also illustrate my case with both service provider and enterprise/business/public sector examples.

The following diagram summarizes the areas impacted -- let’s discuss each one.

SDN 101: What It Is, Why It Matters, and How to Do It

Despite all the buzz about software-defined networking (SDN), many organizations don’t yet have a clear idea of how it will benefit them. In this blog, I’ll tackle the what and why of SDN, and explain the different approaches you can consider.

What: A Disruptive Approach to Network Control

For the last quarter century, network devices have performed two types of processing:

  • The data plane looks at a routing table to decide where to forward packets. This processing takes place in dedicated hardware ASICs.
  • The control plane takes care of everything else, such as spanning tree, AAA, exporting NetFlow statistics, SNMP, and more. The control plane is implemented in software, and you can think of it as the brains of the network element.

So, if your network includes 200, 2000, or 20,000 network devices, that means you’re managing 200, 2000, or 20,000 control planes and keeping all of them up to date. Read More »

Leading the Network Evolution to SDN – Helping You with Your SDN Adoption Strategy

June 23, 2013 at 12:58 pm PST

 

If you are following the industry debates around Software Defined Networking (SDN), and are wondering “What really is SDN?”, “How the concepts of network virtualization and network programmability relate to SDN?” and perhaps more pertinently, “What can it do for my business” and “What network problems, indeed what IT problems, could it solve for my organization?” Well, don’t worry, you are in good company. Many customers looking at SDN are asking exactly these questions.  When I blogged the other week on “The Missing ‘S’ in the SDN Debate”, I mentioned I would write again in more depth on the offerings from Cisco Services that would help you identify and benefit from SDN, the next evolution in the network.  Today, then, I will share more information on the “Cisco Strategy and Analysis Services for Open Network Environment (ONE)”, which helps you gain an appreciation of what SDN is, what Cisco ONE is, and how it will help you.  This service has been design specifically to answer the questions above for you, enabling you to optimize your IT strategy to greatest effect.

First, if you are attending CiscoLive in Orlando this coming week (week of 24 June 2013), please do look out for our “Design Centers” in the Data Center Cloud or Enterprise Networks areas of the Cisco booth.  Here you can discuss your SDN and Cisco ONE questions with Cisco Services’ solutions architects, who have already been running strategy workshops with some of the early adopters of SDN and beta customers of Cisco ONE.
