SDN research Definitions

  • D

    distributed virtual switch

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

  • DOVE (IBM DOVE)

    IBM Dove (Distributed Overlay Virtual Ethernet) is an architecture that allows a network engineer to abstract the physical network infrastructure from hypervisor hosts and make network changes in software rather than hardware.

  • M

    Mininet

    Mininet is a software emulator for prototyping a large network on a single machine. 

  • N

    NETCONF

    NETCONF is an IETF network management protocol that provides an administrator or network engineer with a secure way to configure a firewall, router, switch or other network device.

  • network fabric

    Network fabric is an industry term that describes a network topology in which devices pass data to each other through interconnecting switches.

  • network functions virtualization (NFV)

    Network functions virtualization (NFV) is an initiative to virtualize network functions previously carried out by dedicated hardware.

  • network intelligence (NI)

    Network Intelligence (NI) is the capacity of a network to examine data packets continuously and in real time.

  • network-as-a-service (NaaS)

    Network-as-a-Service (NaaS) is a business model for delivering network services over the Internet on a pay-per-use or subscription basis.

  • Nexus 1000V (Cisco Nexus 1000V)

    The Cisco Nexus 1000V is a Cisco Nexus Operating System (NX-OS) switch rendered fully in software for multi-tenant services composed of both physical and virtual networking resources.

  • 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.

  • OpenFlow Consortium

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

  • 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.

  • P

    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.
