Abstract: An apparatus includes a host interface; a network interface; hardware storage to store a flow table; and programmable circuitry comprising processors to implement network interface functionality and to: implement a hash table and an age context table, wherein the hash table and the age context table are to reference flow rules maintained in the flow table; process a synchronization packet for a flow by adding a flow rule for the flow to the flow table, adding a hash entry corresponding to the flow rule to the hash table, and adding an age context entry for the flow to the age context table; and process subsequent packets for the flow by performing a first lookup at the hash table to access the flow rule at the flow table and by performing a second lookup at the age context table to apply aging rules to the flow rule in the flow table.
