a set of at least one flow table comprising a first set of flow entries for processing packets received by the managed forwarding element, wherein a plurality of packets processed by the managed forwarding element are processed according to a plurality of the flow entries of the first set; an aggregate cache comprising a second set of flow entries for processing packets received by the managed forwarding element, wherein each of the flow entries of the second set is for processing packets of multiple data flows, wherein at least a subset of packet header fields of the packets of the multiple data flows have a same set of packet header field values, and wherein a same set of operations is applied to the packets of the multiple data flows; and an exact-match cache comprising a third set of flow entries for processing packets received by the managed forwarding element, wherein each of the flow entries of the third set is for processing packets for a single data flow having a unique set of packet header field values. |
