    SD-WAN (software-defined WAN)

    Software-defined WAN (SD-WAN) is a technology to distribute network traffic across wide area networks (WAN) that uses software-defined networking (SDN) concepts to automatically determine the most effective way to route traffic to and from branch offices and data center sites.

  • SDN application (software-defined networking application)

    An SDN application is a software program designed to perform a task in a software-defined networking (SDN) environment. SDN applications can replace and expand upon functions that are implemented through firmware in hardware devices in a conventional networking environment.

  • SDN controller (software-defined networking controller)

    An SDN controller is an application in software-defined networking (SDN) that manages flow control to enable intelligent networking. SDN controllers are based on protocols, such as OpenFlow, that allow servers to tell switches where to send packets.

  • SDN overlay (software defined networking overlay)

    An SDN overlay is a deployment method for network virtualization and software-defined networking (SDN) that involves running a logically separate network or network component on top of existing infrastructure.

  • software-defined networking (SDN)

    Software-defined networking (SDN) is an umbrella term encompassing several kinds of network technology designed to make a network agile and flexible like the virtualized server and storage infrastructure of the modern data center.

  • software-defined networking monitoring application (SDN monitoring application)

    An SDN monitoring application is a software program that oversees the traffic in a software-defined network (SDN) as a component of network management.
