Inscrutable alphabet soup. Even the fully expanded terms are only slightly more digestible. But they’re not truly all that confusing: the underlying principles are elegant and illuminating. Software Defined Networking (SDN) is an architecture—first defined circa 1995—that physically separates the network control plane (decisions about traffic flows) from the forwarding plane (moving chunks of data between points A and B). Practically this simply means controlling network hardware devices (think routers, switches, Wi-Fi access points) by using software that is physically hosted elsewhere (think an orchestrator or controller platform). A SDN architecture provides numerous advantages: it abstracts (and simplifies) the entire…

SD-WAN Security Architectures: The Keys to the Cloud Speed is the currency of modern business, and the rate of business change accelerates. Over the span of a hundred and fifty years, Darwin speaks to networking professionals: to survive is to adapt. Cloud-based resources—applications or storage—are prerequisites for today’s adaptability and agility. Okay, so I put a lot of my stuff in the cloud; I migrate to a cloud-delivered SD-WAN and everything goes faster, smoother, easier, I can finally keep pace with the world, I can face the future. But wait, is my stuff secure? Where are the locks? Who holds…




Architecture Matters – Cloud Migration

Cloud migration… sounds nebulous? It doesn’t have to! Mobile or fixed device in hand, you don’t care where the application is as long as it’s there when you need it, on the device you’re using, and performs acceptably. The cloud is increasingly where the application is. And the cloud is—simultaneously—everywhere and nowhere. On the other hand, if you’re the IT professional, the cloud is a very definitive and unambiguous place, more often than not characterized by not being the place where your rigid traditional WAN is optimized to route traffic. Traffic running in a straight line from your branch office…

SD-WAN Architecture… Oh, You Mean There’s More Than One? By now, everyone gets the Traditional WAN, Hybrid WAN, SD-WAN thing. There’s ample talk in the industry about WAN trends. But are all SD-WANs created equal? Not so fast! An evaluation of the landscape could come in really handy. WAN architecture continues to morph and evolve influenced by new technologies, as well as the necessary practicality of incremental migration. Think of this as along two axes: from an on-premise to a cloud-based architecture in one dimension; and in the other dimension from a point product to a comprehensive SD-WAN offering. Industry analyst…




Architecture Matters – With SD-WAN, it’s So Much Simpler!

Years ago a colleague developed UC features for an airline call center and they didn’t want the phones to ring—no, they said quite confidently, just make it dead simple and have the software auto-answer the next call immediately when the previous one disconnects. A ringing call wastes the customer’s and the agent’s time. Shaving just a few seconds off each call compounded into literally annual savings of millions for the airline. So what’s with all this fuss about SD-WAN architecture? You really want it just to be quicker, easier, simpler, less headache, no truck rolls. No logging individually into thousands…
