Abstract

Embodiments of the present invention are directed to a wildcard matching solution that uses a combination of static random access memories (SRAMs) and ternary content addressable memories (TCAMs) in a hybrid solution. In particular, the wildcard matching solution uses a plurality of SRAM pools for lookup and a spillover TCAM pool for unresolved hash conflicts.
