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 20):
The computer system of  claim 18 , wherein determining the change to the topology configuration of the plurality of delivery devices of the software-defined network includes sending link layer discovery protocol packets as a mechanism to discover existing edges of the software-defined network, and determining the change of the topology configuration by comparison to subsequent link layer discovery protocol packet responses.
