The Exact Match Search Engine (EMSE2) IP tracks network flows in 100 Gigabit/second networks using a combination of on-chip memory and off-chip DRAM.

The EMSE2 tracks up to 12M flows simultaneously. It matches N-tuple header fields of widths between 80 to 640 bits, allowing a smooth transition from IPv4 to IPv6. It also supports an aging mechanism to keep track of and delete inactive flows.

The Algo-Logic’s EMSE2 core has the unique ability to store an item along with each entry/key whereas a typical TCAM based system requires an additional memory lookup after a match address has been found. This item is returned along with the match, without an extra memory lookup, thus reducing the cost of the system.
