  • Synchronization of OpenFlow controller devices via OpenFlow switching devices
    Patent number: 9137174
    Abstract: An OpenFlow switching device of an OpenFlow network sends a message including a flow rule received from a first OpenFlow controller device currently active within the OpenFlow network to a second OpenFlow controller device also currently active within the OpenFlow network. As such, the second OpenFlow controller device stays in synchronization with the first OpenFlow controller device. Upon a third OpenFlow controller device becoming newly active within the OpenFlow network, the OpenFlow switching device sends a message including flow rules of the switching device's flow table to the third OpenFlow controller device. As such, the third OpenFlow controller device becomes immediately up-to-date with respect to this flow table.
