Abstract

Example embodiments relate to selective invalidation of packet filtering cache results based on rule priority. In example embodiments, a network node determines whether a rule identifier included in a cache entry of a cache of results of a packet filtering rule set is of a higher priority than a highest priority rule corresponding to a rule set version identifier included in the cache entry. If so, the network node may apply an action included in the cache entry.
