Integrated Device Technology Inc. (IDT) has introduced what it claims is the industry's first monolithic Network Search Engines (NSEs) in 512Kx36 (18Mb) and 256Kx36 (9Mb) configurations with dual Network Processor Forum (NPF) Look Aside (LA-1) interfaces.

The interfaces allow a seamless connection between the NSEs and the network processing units (NPUs), including the nP3700 NPUs from AMCC and the Intel IXP2400, Intel IXP2800, and Intel IXP2850 NPUs.

The dual LA-1 interfaces on the NSEs enable the sharing of databases between ingress and egress NPUs. This feature, coupled with the 18Mb density of the 512Kx36 NSE, enables multiple database support for applications related to multi-field complex classification. The flexibility delivered by the NSE's shared-database capability eliminates the need for multiple updates for rule sets within multiple NPUs.

The products also include a control plane maintenance port with a PCI interface. This port enables efficient table management by allowing users to make changes in the databases without impacting search performance. The NSEs also perform instruction result notification that provides efficient device operation and minimizes the number of transactions required to obtain the search results. Similar to existing devices within the IDT portfolio, the NSEs with dual LA-1 interfaces offer application-support features, such as dynamic database management for increased power savings, and simultaneous multi-database lookup (SMDL) that enables multiple packet searches up to 250MSPS.

Targeted at metro and edge routers, the products enable line rate performance up to OC-192, and are packaged in a 900-ball FCBGA. The NSE in a 512Kx36 configuration is expected to be priced individually at $350 in 10,000-unit quantities.

The NSEs are offered with a design accelerator kit, consisting of software and hardware development tools. The software development kit includes a dual-port system level architecture model, a simulation tool, bundled with the BusTracker and PowerTracker system analysis tools.
