Abstract:
A controller of a software-define network receives a notification of a change to a configuration of data delivery devices of the network. In response, the controller determines whether flows of respective flow tables of the data delivery devices are affected by accessing flow mappings maintained in a memory of the controller. The respective flow tables of the data delivery devices affected by the configuration change include a pattern of information fields and actions that corresponds to a pattern of information fields and actions of the flow mappings in the memory of the controller. The controller sends instructions to the affected data delivery devices to perform an asynchronous activity on the respective flow tables that includes a cleanup of the flows of the respective flow tables of the affected data delivery devices, performed in repetitive sweeps of the one or more data delivery devices, until completion of the cleanup.

Claim (Index 10):
A computer program product for managing flows of a software-defined network, the computer program product comprising:\n one or more computer readable storage media wherein the computer readable storage medium is not a transitory signal per se, and program instructions stored on the one or more computer readable storage media, the program instructions comprising:\n program instructions to receive within an software-defined network, a notification of a change to a configuration of a plurality of data delivery devices of the network; \n responsive to receiving the notification of the change to the configuration of one or more data delivery devices of the plurality of data delivery devices, program instructions to determine whether one or more flows of respective flow tables of the plurality of data delivery devices are affected as a result of the change to the configuration, by accessing flow mappings maintained in a memory of the controller, in which the respective flow tables of the one or more data delivery devices that are affected by the change to the configuration include a pattern of information fields and actions that corresponds to a pattern of information fields and actions of the flow mappings maintained in the memory of the controller; and \n program instructions to send to the one or more data delivery devices that are affected by the change to the configuration, instructions to perform an asynchronous activity on the respective flow tables of the one or more data delivery devices, wherein the asynchronous activity includes a cleanup of the one or more flows of the respective flow tables of the one or more data delivery devices, performed in repetitive sweeps of the one or more data delivery devices, until completion of the cleanup.
