SDN management applications Definitions

  • A

    application-aware networking (app-ware networking)

    Application-aware networking is the capacity of an intelligent network to maintain current information about applications that connect to it and, as a result, optimize their functioning as well as that of other applications or systems that they control.

  • application-defined networking

    Application-defined networking (ADN) is a networking scenario in which applications have the ability to adapt network environments to meet their needs, rather than having resources allocated by the network.

  • Arista Extensible Operating System (Arista EOS)

    Extensible Operating System (EOS) is a scalable network operating system (OS) that offers high availability, streamlines maintenance processes, and enhances network security.

  • B

    Big Switch Big Network Controller

    Big Network Controller is the SDN controller for the Open Software Defined Network (SDN), a product suite for network virtualization released in November of 2012 by Big Switch Networks.

  • Big Switch Networks Big Tap

    Big Tap is a network monitoring application that runs on Big Network Controller, the SDN controller for the Open Software-Defined Network (SDN).

  • Big Switch Networks Big Virtual Switch

    Big Virtual Switch is a data center network virtualization application that runs on Big Network Controller, the SDN controller for the Open Software-Defined Network (SDN).

  • D

    distributed virtual switch

    A distributed virtual switch is an abstract representation of multiple hosts defining the same name, network policy and port group.

  • F

    FlowVisor

    FlowVisor is an experimental software-defined networking controller that enables network virtualization by slicing a physical network into multiple logical networks.

  • P

    Path Computation Element (PCE)

    Path Computation Element (PCE) is a network component, application or node that can apply computational constraints and compute a network path or route based on a network graph. The PCE has access to topology information for the entire network and uses this in path computations.

  • Policy and Charging Rules Function (PCRF)

    Policy and Charging Rules Function (PCRF) is the part of the Evolved Packet Core (EPC) that supports service data flow detection, policy enforcement and flow-based charging.

  • S

    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.

  • 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.
