Abstract
A network traffic management apparatus includes a first memory including a flow cache table including a plurality of entries. The network traffic management apparatus further includes configurable hardware logic coupled to the first memory and a processor, the configurable hardware logic including a valid split table including a plurality of entries, wherein each of the plurality of entries includes a validity bit. The configurable hardware logic is configured to implement periodically determining whether the validity bit of each of the valid split table entries is set. Additionally, the configurable hardware logic is further configured to implement retrieving one of the plurality of flow cache table entries corresponding to an index value associated with one of the valid split table entries, when it is determined that the validity bit of the one of the valid split table entries is set.
