An exact-match flow table structure of an integrated circuit stores flow entries. Each flow entry includes a Flow Id and an action value. Each Flow Id is a multi-bit digital value that uniquely identifies a flow. A Flow Id does not include any wildcard indictor. The flow table structure cannot and does not store an indicator that any particular part of a packet should be matched against any part of a Flow Id. In one example, a packet is received onto the integrated circuit. A Flow Id is generated from the packet. If the flow table structure determines that the Flow Id is a bit-by-bit exact-match of any Flow Id of any stored flow entry, then the packet is handled according to the action value of the flow entry. If, on the other hand, there is not exact-match, then a miss indication is output from the integrated circuit.
