It’s no secret that networks are complex and demand constant care and attention to ensure that they remain functional and operational. The number of applications and services supported by a corporate network incrementally add complexity and, in the absence of processes or solutions that simplify its management, organizations tend to throw people at the problem. But there is a better way. With Outcome-Driven Networking, organizations are changing the way that networks are managed and maintained. It introduces a level of intelligence, learning, and automation that has not been present before, streamlining and aggregating activities into a single-click. Using Outcome-Driven Networking,…

Original post: With IDC now reporting that the software defined WAN (SD-WAN) market is set to hit $8B by 2021, it’s become to networking what the Cloud has become to infrastructure and applications. Most people now understand what SD-WAN means, but it’s still confused with its technology parent, Software Defined Networking (SDN). In this post, our guest blogger, Yulia Duryea with Windstream, explains the difference.   “SD” isn’t the only thing SD-WAN and SDN have in common Beginning with the separation of the Control Plane and the Data Plane, both SD-WAN and SDN share a common heritage. Designed to…

It’s easy to be confused by the abundance of new terms and buzzwords crowding the industry on a daily basis, but no more so than when they are all in the form of an acronym: SD-WAN, SDN, NFV, and VNF. They all sound similar, but we’re often asked to explain how they are the same or different from one another, and more importantly, can they work together in a single environment? Or do you have to choose one and stick to it? In this blog, we’ll take a look at SDN, NFV, and VNFs in relation to SD-WAN and our…

SDN, SD-WAN, NFV, VNF: What Is All This?

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…
