OpenFlow Plugin


The OpenFlow Plugin project provides the following functionality:

  • OpenFlow 1.0/1.3 implementation project: This provides the implementation of the OpenFlow 1.0 and OpenFlow 1.3 specification.

  • ONF Approved Extensions Project: This provides the implementation of following ONF OpenFlow 1.4 feature, which is approved as extensions for the OpenFlow 1.3 specification:

    • Nicira Extensions Project: This provides the implementation of the Nicira extensions. Some of the important extensions implemented are Connection Tracking Extension and Group Add-Mod Extension

  • OpenFlow-Based Applications Project: This provides the following applications that user can leverage out-of-the-box in developing their application or as a direct end consumer:

    OpenFlow-Based Applications



    Forwarding Rules Manager

    Application provides functionality to add/remove/update flow/groups/meters.

    LLDP Speaker

    Application sends periodic LLDP packet out on each OpenFlow switch port for link discovery.

    Topology LLDP Discovery

    Application intercept the LLDP packets and discover the link information.

    Topology Manager

    Application receives the discovered links information from Topology LLDP Discovery application and stores in the topology yang model datastore.

    Reconciliation Framework

    Framework that exposes the APIs that consumer application (in-controller) can leverage to participate in the switch reconciliation process in the event of switch connection/reconnection.

    Arbitrator Reconciliation

    Application exposes the APIs that consumer application or direct user can leverage to trigger the device configuration reconciliation.

    OpenFlow Java Library Project

    Provides the OpenFlow Java Library that converts the data based on OpenFlow plugin data models to the OpenFlow java models before sending it down the wire to the device.


    Reconciles the state using Openflow 1.4 bundles.
