NSEs feature dual NPF LA-1 interfaces
IDT has developed the industry's first monolithic network search engines in 512K x 36 (18Mbit) and 256K x 36 (9Mbit) configurations with dual Network Processor Forum LA-1 interfaces
IDT has developed the industry's first monolithic network search engines in 512K x 36 (18Mbit) and 256K x 36 (9Mbit) configurations with dual Network Processor Forum (NPF) Look Aside (LA-1) interfaces. The fully integrated interfaces allow a seamless connection between the new IDT NSEs and the network processing units (NPUs), including the nP3700 NPUs from AMCC and the Intel IXP2400, Intel IXP2800, Intel IXP2850 NPUs.

Targeted at metro and edge routers, the new IDT NSEs operate at up to 250 million searches per second and enable line rate performance up to OC-192 and beyond.
The dual LA-1 interfaces on the new IDT NSEs enable the sharing of databases between ingress and egress NPUs.
The flexibility delivered by the NSE's shared-database capability eliminates the need for multiple updates for rule sets within multiple NPUs, increasing overall performance and system efficiency.
In addition to incorporating two LA-1-compliant interfaces, the new IDT NSEs 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 minimises 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 multiple-database lookup (SMDL) that enables multiple packet searches up to 250 million searches per second.
IDT also offers a design accelerator kit (DAK), consisting of software and hardware development tools.
The IDT software development kit (SDK) includes a dual-port system level architecture model (SLAM), a simulation tool, bundled with the IDT BusTracker and PowerTracker system analysis tools that evaluate bus efficiency and power consumption, respectively.
IDT will also provide a hardware development kit (HDK) comprising a suite of tools that can be used in conjunction with the Intel and AMCC NPU development platforms.
