Abstract
A network appliance can be configured for storing a plurality of flow table entries in a flow table of a match-action pipeline, wherein the match-action pipeline is implemented via a packet processing circuit configured to process a plurality of network traffic flows associated with the plurality of flow table entries. An extended packet processing pipeline of the network appliance can read a flow table entry of the flow table. The extended packet processing pipeline can be implemented via a pipeline circuit. The extended packet processing pipeline can determine that a network traffic flow associated with the flow table entry is expired or terminated. The network appliance can delete the flow table entry from the flow table by processing a traffic flow deletion operation after determining that the network traffic flow is expired or terminated.
