Network Search Engine

A fourth generation network search engine(NSE) architecture by Integrated Device Technology Inc. is designed to accelerate the Internet Protocol version 6 ( IPv6) and enable value-added services in 10G-bit per second applications.

The architecture's quad simultaneous multi-database lookup (SMDL) feature will be capable of one billion searches per second(BSPS), four times the current (as of 2004) search engine performance, by supporting four simultaneous lookups in one cycle with a core search rate of 250 million searches per second (MSPS) . The new architecture supports a base search width of 80 bits, a 320-bit search width to accommodate a 296-bit wide IPv6 5-tupe look up and has an optimum database search size for IPv6 operations. With IPv6 services such as VoIP, the proliferation of CPE devices, increasing complexity of access control lists, Web TVs and IPv6 based media are driving the need for NSEs especially in switch and carrier router development where a system vendors property needs to be protected.

An error correction code feature alerts of potential soft errors, ensuring data integrity and complying with stringent service level agreements. Soft errors are unacceptable in high-reliability computers. Soft errors are immediately corrected before it can affect functionality.
