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.
