Search Accelerators, for 40 Gbps applications and beyond
 
Product Description
 

Anticipating and addressing the packet processing needs of next generation networking applications up to 40 Gbps and beyond, the search accelerator assists packet header processing with industry leading performance and service capabilities at wire speed. Search accelerators are vital solutions helping solve network challenges such as triple play convergence, complex multi-layer Ethernet protocols in metropolitan networks, zero packet loss, increasing security and access control, broader address spaces, and increasing importance of system reliability; all of which are placing unprecedented demands on search capability for packet header processing.

As with the IDT family of award-winning network search engine solutions, the 75S10000A accelerates packet flow by offloading classification and forwarding lookups from packet processing elements such as network processors and application specific integrated circuits (ASICs). With the ability to launch four parallel searches, search performance is quadrupled, allowing the search accelerator to enable a broader range of services to be applied to packet-based traffic at high line rates. Utilizing an innovative architecture optimized to support wider search keys and complex IPv6-based traffic without compromises, the search accelerator is also the first search solution to implement enhanced error detection and correction (ECC) ensuring data integrity. The combination of these elements results in a solution that provides industry leading search performance, rich services support, and the highest reliability available for search acceleration of packet based traffic.

Features and Benefits
 
Feature
Benefits
One billion searches per second (BSPS) performance
Supports multiple lookups for packet processors providing aggregate 10G (10GbE, 8x1GbE, OC192) and 40G (4x10GbE, OC-768) performance
Quad Simultaneous Multi-Database Lookup (qSMDL)
Allows our customers to search multiple application databases with the same search key, allowing simultaneous comparisons of IP forwarding, Netflow, access control, and QoS/CoS databases to reduce system latency and improve overall system line-rate performance
Base search width of 80-bits
Only architecture truly optimized for IPv6 by offering a 320-bit search width to accommodate typical 296-bit wide IPv6 5-tuple look-ups, improving search performance to accelerate application delivery for IPv6-enabled networks as well as enhancing storage capacity for IPv6 entries
Double Data Rate (DDR) interface with equivalent clock input and core search rate
Simplified clocking scheme enables designers to use less expensive components with improved signal integrity and a simplified termination scheme, decreasing the cost and complexity of the overall design
Integrated error code correction and bus parity scan engine
By improving data integrity and addressing any soft errors that may be induced by the 1V core voltage, helps our customers improve system reliability and guarantee higher system uptime to their service provider and enterprise customers
Dynamic Database Management and Iterative Entry Management
Two power saving techniques that work in tandem to selectively reduce the number of entries being searched during table lookups to reduce power consumption by up to 75%
Automatic Entry Recycling
Tracks and reports entry usage within the network search accelerator, identifying entries that are infrequently used for easy removal and replacement
