Abstract
A flow manager may receive packet flow rules from one or more network services and may generate a unified rule set according to the received packet flow rules. A flow manager may additionally split the unified rule set into subsets for enforcement by one or more flow enforcement devices and may install the rule subsets onto the flow enforcement devices. When splitting the unified rule set into subsets, a flow manager may analyze a network topology connecting the flow enforcement devices. A flow manager may also receive additional packet flow rules, integrate them into the unified rule set, update the rule subsets according to the additional rules, and install the updated subsets onto the flow enforcement devices.
