IDT Debuts 250 MSPS Network Search Engine with 512Kx36 Lookup

6/24/2003 - IDTTM (Integrated Device Technology, Inc.; Nasdaq: IDTI), a leading communications IC company and the leading provider of network search engines (NSEs), announced the availability of the industry’s highest-performance network search engine in an 18-Mbit, 512Kx36 (256Kx72), configuration. Operating at up to 250 million searches per second (MSPS), the new IDT 75K72100 NSE offers designers the ability to simultaneously search in separate, mutually exclusive databases, increasing the search rate to support multiple full-speed OC-192 packet searches per instruction with a single device. Targeting core, metro and edge routers, the new device enables higher-performance systems to achieve increased packet processing rates and facilitates additional services, through simultaneous database lookup (SMDL) and sophisticated next free address (NFA) capabilities. As part of its commitment to provide comprehensive system solutions, IDT also offers a design accelerator kit (DAK) that speeds hardware and software development for advanced networking packet processing subsystems.

“Increased data transmission through core, metro, and edge routers requires high-density NSEs to aid faster packet search rates,” said Jag Bolaria, senior analyst at The Linley Group. “A key enabler for this market will lie in the availability of NSEs that can satisfy the classification requirements of multiple OC-192 data paths.”

“The new IDT 75K72100 NSE with industry-leading performance of 250 MSPS extends our family of pin and function compatible high-performance NSEs and enables our customers to prolong the life of their designs through greater system throughput and flexibility,” said Dave Cech, director of marketing for IDT network search engine products. “The unique search capabilities of the 512Kx36, 18-Mbit NSE meet the requirement for multiple lookups and increased performance in today’s systems, while our software and hardware tools help designers get to market faster and at a lower cost.”

The additional density provided by the IDT 75K72100 NSE allows for increased port support per line card and virtual route table needs in equipment providing OC-192 performance. The device’s unique set of application support features, such as dynamic database management and SMDL, allow efficient multiple packet searches. For example, a Metro Ethernet application can now simultaneously launch virtual private networking (VPN) ID lookups as well as anti-spoofing virtual local area network (VLAN) validation lookups. Parallel lookups of this type can also be applied to other commonly used routing functions such as forwarding, access control lists (ACL) and flow caching, and allow for reduced latency in execution pipelines.

The device also shares the advanced feature set available with previous products in the IDT high-performance NSE family that improve system performance and lower power consumption when compared to alternative solutions. This latest addition offers designers the ability to seamlessly upgrade from devices in 64Kx36 through 512Kx36 configurations (2-Mbit through 18-Mbit densities) and up to 250 MSPS.

Comprehensive Design Accelerator Kit Lowers Development Costs
In conjunction with this new silicon offering, IDT is providing a comprehensive DAK comprised of software and hardware development tools. The IDT software development kit (SDK) includes initialization, management and search (IMS) libraries to provide a standard API and accelerate software design, as well as schematics for board layout and connectivity. The IDT hardware development kit (HDK) includes a Verilog model and schematic acceleration symbols, as well as Verilog and VHDL interface code for easy portability to popular FPGA/CPLD solutions. Together, these tools speed designers’ time to market, increase system performance and lower overall development costs.

Pricing and Availability
The IDT 75K72100 512Kx36 full-ternary NSE is available now and is priced at $350 each in 10,000-unit quantities. Click here for additional product information.

IDT IP Co-Processor Solutions
IDT provides a family of IP co-processor solutions, including industry-leading network search engines and content inspection engines that accelerate packet processing and enable intelligent application management in next-generation networking equipment. IDT is recognized by RHK, Inc. and International Data Corporation (IDC) as the technology leader, and as the volume shipment leader of network search engines. Based on the integration of ternary content addressable memory (TCAM) and high-performance logic, the IDT NSEs support NPUs and ASICs to accelerate packet classification and forwarding in core, metro and access networks. IDT offers the industry’s highest-performance NSE operating up to 250 MHz and the first NSE with an integrated LA-1 interface, and was the first vendor to introduce search widths up to 576 bits. The IDT NSE portfolio includes custom versions for Cisco Systems, as well as merchant versions with high performance interfaces and glue-less interfaces to leading network processors. The IDT 256Kx36 (128Kx72) NSE received the EDN Top 100 Products Award of 2002.

The IDT content inspection engines are capable of parsing and classifying data up to Layer 7, a functionality that, when coupled with the NSEs, allows for inspection of content in both the packet header and payload, resulting in more intelligent packet processing at wire speed. IDT is an active NPF member and contributor to NPF and the LA interface definition and serves as chairman of the board.
