Vendors Sample High Performance Network Search Engine from Cypress

7/1/2003 - Cypress Semiconductor (NYSE: CY), announced that it is sampling the AyamaTM 10000 NSE family of network search engines (NSEs), optimized for multi-protocol packet classification and forwarding at 266 million searches per second (MSPS), effectively doubling the search performance of existing NSE solutions. Designed to work with both ASICs and FPGAs, the Ayama 10000 NSE family enables networking vendors to quickly deploy equipment that supports complex packet search capabilities at wire-speeds of 10 Gbps and beyond.

In Internet routers and switches, NSE search subsystems accelerate packet processing by offloading search functions from the network processing ASIC or FPGA. With the explosive growth of the Internet, routers need to execute forwarding and policy searches: determining destinations, service levels, billing and other parameters for a data stream that includes a number of different data types and protocols—all of it streaming by at up to 10 Gbps. This is well beyond the capability of current software/FPGA solutions and is only possible using advanced NSEs such as the Ayama 10000.

“At both the enterprise and service provider level, customers are demanding new services such as multi-protocol label switching (MPLS), voice over IP (VoIP), and virtual private networks (VPNs) that have ever-increasing quality of service (QoS) and cost of service (CoS) requirements,” said Christopher Norris, Vice President of Cypress’s Data Communications Division. “This has created a tremendous burden on packet processing subsystems, since these services require multiple searches per packet. The only way to keep up with these demands and increasing line-rate requirements is to offload the search function to dedicated hardware. Cypress’s Ayama 10000 NSE family addresses this requirement at an industry-leading 266 MSPS.”

“Cypress’ new Ayama 10000 NSE family is changing the way system designers think about their search subsystem,” said Betsy Van Hees, senior memory analyst for market research firm iSuppli Corp., El Segundo, Calif. “By offloading the search function, they are able to offer additional services at increasing wire-speeds. Cypress’s 266 MSPS performance keeps up with current and future search system requirements.”

The Ayama 10000 NSE Family
The Ayama 10000 NSE family features the CYNSE10512, an ultra-high-density 512K entry (18 Mbit) NSE with high performance (266 MSPS) and low power. In addition, the NSE family includes the 256K-entry (9 Mbit) CYNSE10256 and 128K-entry (4.5 Mbit) CYNSE10128. The Ayama 10000 NSE family is an ideal solution for applications that require large routing tables, supporting both IPv4 and IPv6, as well as wire-speed packet processing. The family is backward compatible with Cypress’s industry leading NSE70000 family. Designed to work with ASICs and FPGAs, the Ayama 10000 NSE family includes a full ternary content-addressable memory (CAM) array with per-bit masking. This enables it to efficiently accomplish a variety of searches for applications ranging from packet forwarding to complex multi-protocol classification.

At 266 MSPS, the Ayama 10000 NSE more than doubles the performance of existing NSEs in the market today. Its advanced Mini-KeyTM power management capability dramatically reduces power consumption as much as 70% by engaging only the portion of the NSE array that contains entries of interest. In addition, the Ayama 10000 NSE’s Soft PriorityTM table management feature helps maintain data integrity at wire speeds by enabling dynamic prioritization of entries for longest prefix match (LPM) in Layer 3 forwarding applications, eliminating the latency associated with routing table updates. Parity at the core and I/O provides protection to ensure data integrity throughout the search subsystem.

Cypress’s new software platform, CynapseTM SP, offers a wide variety of tools to complement the Ayama 10000 NSE family’s new hardware features. Cypress provides a reference design kit (RDK) to aid in the design-in process and reduce time-to-market for system designers. Its contents include application notes, FPGA reference code, hardware and software behavioral models, device models (IBIS and BSDL), and schematic and layout symbols.

Cypress’s Network Search Engines
The AyamaTM10000 family of NSEs will maintain the Cypress lead in commercial TCAM market by extending the speed and density of the most successful commercial NSE family to date, the NSE70000 family. The NSE70000 family includes 32K, 64K, 128K, and 256K entry devices with speeds up to 100 MSPS.

The Ayama 20000 NSEs will incorporate all the features of Ayama 10000 NSE along with LA-1 interface, a standard adopted by the NPF. The Ayama 20000 NSE devices will provide a glue-less connection to Intel’s IXP2400/2800 network processors and AMCC’s next-generation network processors that support the LA-1 standard.

Pricing and Availability
All devices in the Ayama 10000 NSE family are sampling now. Pricing for the 512K x 36-bit CYNSE10512 starts at $275, the 256K x 36-bit CYNSE10256 starts at $135, and the 128K x 36-bit CYNSE10128 starts at $75 for 10k unit quantities. All three devices are available in 388-ball BGA packages.
