SDN

In my last two blogs I discussed the challenges Enterprises are facing for their WAN, the differences between Enterprise needs in their LAN and WAN, and how the traditional ONF model for SDN isn’t practical for the Enterprise WAN.  Let’s now look at how the new Cisco ONE Enterprise Architecture can…

In my last blog I introduced challenges Enterprises are facing in their WAN deployments and the definition of ONF SDN. While the broad definition of ONF’s SDN architecture implies many theoretical answers to these challenges, we need to be pragmatic. Let’s take a look at the practical differences in…

As the long awaited innovation in the networking space moves out of hype cycle and market interest in software defined networking (SDN) steadily rises, Cisco has been actively involved in these emerging trends, working with standards bodies and listening to the requirements of our global customer ba…

The Software Defined Networking (SDN) market evolution is having a major effect on networking job roles. New careers in IT are being built, focusing more on complex services and architectures rather than systems. A recent survey by Cisco found that 71 percent of IT professionals intend on using SDN…

Welcome to another episode of Engineers Unplugged. This week’s topic is Next-Gen Storage, handled admirably by Cisco’s J Metz (@drjmetz) and Stephen Foskett (@sfoskett). What will the topology of the future look like? What is the tech evolution that will drive adoption? From token ring t…

Network programmability means democracy, means freedom, freedom to program across all layers and entities, software or hardware – depending on your needs. Is SDN required to have network programmability? Not at all. Does the SDN architecture leverage network programmability? Yes, of course.  So, why…

Thanks to SDN, the “Controller” word pops up in many network architecture discussions these days. In networking alone, we’re already surrounded by many “controllers” and we’re busy introducing more as we speak:  For example, Session Border Controllers or Wireless LAN Controllers have been around for…

Having been part of the team who developed the Cisco Cloud Enablement Services, our professional services to help customers enable and adopt cloud computing, I was absolutely delighted watching the CiscoLive! keynote yesterday to hear Padmasree Warrior announce the results of the March 2013 IDC mark…

I admit it. I’ve grown weary of the debate about whether SDN includes network programmability or whether or not SDN can only be accomplished through NfV, or the relative merits of control plane / dataplane separation. I will leave those debates to others more focused on the technology itself.  Perso…
