Abstract
A networking device includes: 1) a first processor that includes a match table, and 2) a second processor that includes both a Flow Tracking Autolearning Match Table (FTAMT) as well as a synchronized match table. A set of multiple entries stored in the synchronized match table is synchronized with a corresponding set of multiple entries in the match table on the first processor. The FTAMT, for a first packet of the flow, generates a Flow Identifier (ID) and stores the flow ID as part of a new entry for the flow. The match of a packet to one of the synchronized entries in the synchronized match table causes an action identifier to be recorded in the new entry in the FTAMT. A subsequent packet of the flow results in a hit in the FTAMT and results in the previously recorded action being applied to the subsequent packet.
