SDN Definitions

  • N

    NFVi (network functions virtualization infrastructure)

    NFVi (network functions virtualization infrastructure) is a pool of virtual and physical resources that enables the deployment of virtual network functions in carrier networks. Service providers use NFVi to create environments that enable NFV.

  • Nicira Inc.

    Nicira is a network virtualization and SDN (software-defined networking) company that Martin Casado, Nick McKeown and Scott Shenker founded in 2007.

  • Nicira Network Virtualization Platform (Nicira NVP)

    Nicira NVP is network virtualization software that manages an abstraction layer between end systems and the physical network infrastructure and enables the creation of independently operable virtual networks.

  • NOX

    NOX is an open source development platform for C++-based software-defined networking (SDN) control applications.

  • NVGRE (Network Virtualization using Generic Routing Encapsulation)

    NVGRE (Network Virtualization using Generic Routing Encapsulation) is a network virtualization method that uses encapsulation to create large numbers of virtual LANs (VLANs) for subnets that can extend across dispersed data centers and Layers 2 and 3.

  • NX-OS

    NX-OS evolved from the Cisco MDS operating system, SAN-OS.

  • O

    ODIN (Open Data Center with an Interoperable Network)

    ODIN (Open Data Center with an Interoperable Network) is a reference architecture that describes best practices for creating a flat, converged, virtualized data center fabric based on open industry standards.  

  • OF-Config (OpenFlow Configuration and Management Protocol)

    The OpenFlow Management and Configuration Protocol (OF-Config) is a protocol developed under the Open Networking Foundation used to manage physical and virtual switches in an OpenFlow environment.

  • ONOS (Open Network Operating System)

    ONOS (Open Network Operating System) is an operating system (OS) designed for network service providers to help build carrier-grade software-defined networks architected for high scalability, availability and performance

  • OpenFlow Consortium

    The OpenFlow Consortium was a collaborative group of university researchers and network administrators that developed the original specification for the OpenFlow protocol.

  • OpenFlow controller

    An OpenFlow controller is an application that manages flow control in a software-defined networking (SDN) environment.

  • OpenFlow switch

    An OpenFlow switch is a software program or hardware device that forwards packets in a software-defined networking (SDN) environment.

  • OpenStack Neutron (formerly called Quantum)

    OpenStack Neutron is a cloud networking controller and a networking-as-a-service project within the OpenStack cloud computing initiative.

  • overlay network

    An overlay network is a telecommunications network that is built on top of another network and is supported by its infrastructure.

  • OVSDB (Open vSwitch Database Management Protocol)

    The Open vSwitch Database Management Protocol (OVSDB) is an OpenFlow configuration protocol that is designed to manage Open vSwitch implementations.
