Search engine ante goes to 250 million searches/sec

By Nicholas Cravotta -- EDN, 8/21/2003

IDT has announced the 75K72100 network-search engine (Picture). The 18-Mbit TCAM (ternary content-addressable memory) is available in 512k×36- or 256k×72-bit configurations and can perform as many as 250 million searches/sec. Employing features such as dynamic database management, simultaneous database lookup, and sophisticated next-free-address capabilities, the engine supports parallel searches in separate, mutually exclusive databases for functions such as forwarding, access-control lists, and flow caching. For example, a metro router could simultaneously look up virtual-private-networking IDs and antispoofing virtual-LAN-validations.

Hardware- and software-development kits include initialization, management, and search software libraries with API, Verilog model, and Verilog and VHDL interface codes to ease porting to FPGA/CPLDs. Available now, the 75K72100 comes in a 372-ball BGA package for $350 (10,000). For product information, visit www.idt.com/products/nse.html.
