The NSE2032 is a 1 megabit network search engine device organized as 8K words each of 128-bit width. The NSE2032 device performs high-speed parallel search operations on database entries. Its primary application is as an address filter or an address translator for Fast Ethernet, Gigabit Ethernet, and ATM switches. The NSE2032 is an ideal fit for Layer 3 and higher routing applications.

The NSE2032 has a mask word associated with every data word. The user is able to mask entries on a bit-by-bit basis (granularity of 1 bit). The nature of this NSE is ideal for enabling policy enforcement and packet classification for differentiated services in edge, campus, and enterprise networking applications.
