Algorithmic search engine cuts overheads
The Sahasra 50000 NSE is billed as the industry's first single-chip algorithmic search engine
Cypress Semiconductor Corp is now sampling the Sahasra 50000 network search engine (NSE), billed as the industry's first single-chip algorithmic search engine. This new device offers superior price/performance for longest prefix match (LPM) and exact match packet classification applications, and is especially effective for high-capacity forwarding applications (one-million entries and above) where traditional solutions may not be cost effective.

The adoption of IPv6 and other new protocols, combined with increasing line rates and the need to support advanced network services such as virtual private networks (VPNs) and virtual router forwarding (VRF), puts tremendous strain on packet classification subsystems.
By combining advanced search algorithms and high-performance memory on a single chip, the Sahasra 50000 NSE provides the optimal solution for forwarding applications.
The deterministic, high search performance of 250Msearch/s, and the ability to support as many as 1.5-million IPv4 routes in a single chip, allow the Sahasra device to offer the lowest cost-per-route of any network search engine solution in the market today.
The integrated SRAM at the core of the Sahasra device enables full speed performance while consuming as little as 10% of the power of a comparable TCAM-based solution.
This, coupled with the TCAM-like interface of the Sahasra device will greatly reduce system level design complexity.

'We are very excited to be able to offer customers an algorithmic device to complement our portfolio of TCAM-based search solutions', said Cathal Phelan, Vice President of Cypress's Data Communication Division.
'Our customers have repeatedly told us that to address large forwarding tables, they need a solution with the performance of a TCAM but at lower cost and power'.
'Coupled with the ease of migration from an existing TCAM-based solution, the Sahasra 50000 family delivers on our commitment to provide easy-to-use, leading edge search solutions'.
'Sampling of the Sahasra 50000 NSE is a major milestone for Cypress, and the search engine market as a whole', said Jag Bolaria, Senior Analyst with The Linley Group, the leading independent analyst in the networking silicon industry.
'This further establishes Cypress as the technology leader in the search engine market, with the broadest portfolio of high performance search solutions'.
The Sahasra 50000 NSE is supported by a complete software solution, the Cynapse software platform, which includes the production-ready table management code as well as models and documentation to support the design-in process.
The Cynapse architecture allows migration between the various Cypress NSE families with minimal application level code changes.
This architecture, coupled with the interface characteristics of the Sahasra device, allows easy software and hardware migration from existing solutions.
