A method for managing flow of packets comprises inputting a plurality of flow rules of various priorities to a router having a plurality of hardware resources, the plurality of hardware resources having varying levels of capability relative to each other. A first rule, for example a rule having a lowest priority, may be selected from among the plurality of flow rules, and it may be determined whether the first rule conflicts with any lower priority rules stored in the hardware resource with a highest capability. If the first rule conflicts with a lower priority rule in the hardware resource with the highest capability, the first rule may be stored in the resource with the highest capability. If the first rule does not conflict with a lower priority rule in the hardware resource with the highest capability, the first rule may be processed to identify the hardware resource with a lowest capability that can support the first rule, and the first rule may be stored in the identified resource.
