The next generation of networking technologies is here. Software Defined Networking, or SDN for short, is a better way to utilize your network. SDN, built on the OpenFlow standard, adds a plane of intelligence to your network infrastructure that is separate from the hardware (aka switches and routers), but allows you to control network flows and optimizes them dynamically to your specific needs. In effect, the SDN “Controller” application, redefines how the hardware handles traffic, and gives you better control and security than what was possible before.
Software Define Access
Built on the principles of intent-based networking, SD-Access helps organizations enable policy-based automation from the edge to the cloud.
SD-Access gives network architects the tools to orchestrate key business functions like onboarding, secure segmentation, IoT integration, and guest access.
SD-Access automates user and device policy for any application across the wireless and wired network via a single network fabric.
Software Define WAN
SD-WAN is an acronym for software-defined networking in a wide area network (WAN). SD-WAN simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. This concept is like how software-defined networking implements virtualization technology to improve data center management and operation.
A key application of SD-WAN is to allow companies to build higher-performance WANs using lower-cost and commercially available Internet access, enabling businesses to replace more expensive private WAN connection technologies partially or wholly such as MPLS.
American marketing research firm Gartner predicted in 2018 that by 2023 more than 90 percent of WAN edge infrastructure refresh initiatives will be based on virtualized customer premises equipment (vCPE) platforms or SD-WAN software/appliances.
