  • Systems and methods for implementing multi-table OpenFlow flows that have combinations of packet edits
    Patent number: 11799780
    Abstract: Systems and methods are provided herein for implementing multi-table OpenFlow flows that have combinations of packet edits. This may be accomplished by a network device receiving a first flow entry with a first set of actions to be installed into a flow table. The network device may determine that the first set of actions includes edits to a plurality of fields of a matched data packet. In response, the network device may change the first set of actions of the first flow entry to edit a first field of the data packet and create a second flow entry with a second set of actions to edit a second field of the data packet. The network device may install the first and second flow entries into one or more flow tables of the network device.
    Type: Grant

  • System and method for processing messages during a reboot of a network device
    Patent number: 10841160
    Abstract: In some implementations, a method is provided. The method includes determining that a network device will perform a reboot. The method also includes saving state information. The state information comprises data used by the network device to process address resolution protocol (ARP) messages. The method further includes initiating the reboot of the network device. The method further includes initiating a first ARP service. The first ARP service is configured to process ARP messages during the reboot of the network device.
