Network flow management system
A network flow management system includes controllers that are each coupled to a subset of switch devices, and a flow management server system that is coupled to each of the controllers. The flow management server system collects first-level flow information for the switch devices from the controllers, and filters and structures the first-level flow information to generate second-level flow information. The flow management server system then analyzes the second-level flow information based on current flow operation policies that are configured to cause the switch devices to perform first flow operations and, in response, determines flow operation policy changes. The flow management server system then distributes updated flow operation policies that includes the flow operation policy changes to each of the controllers, where the updated flow operation policies cause the switch devices to perform second flow operation that are different than the first flow operations.
