Each flow entry includes a Flow Id. A flow entry is generated from an incoming packet. The flow table structure determines whether there is a stored flow entry, the Flow Id of which is an exact-match for the generated Flow Id. In one novel aspect, a programmable reduce table circuit is used to generate a Flow Id. A selected subset of bits of an incoming packet is supplied as an address to an SRAM, so that the SRAM outputs a data value. The data value is supplied to a programmable lookup circuit such that the lookup circuit performs a selected type of lookup operation, and outputs a result value of a reduced number of bits. A multiplexer circuit is used to form a Flow Id such that the result value is a part of the Flow Id."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Making a flow ID for an exact-match flow table using a programmable reduce table circuit","description":"An exact-match flow table structure stores flow entries.
