Introduction
Evolving network speeds require critical functions such as forwarding
and classification to migrate towards dedicated hardware devices. The
Network Search Engine (NSE) based on IDT's CAM (Content Addres-
sable Memory) technology accelerates search functions required for
applications such as Access Control Lists (ACL), Flow Caching and
Forwarding.
Device Description
The NSE with a single QDR™ (Quad Data Rate) interface is intended
to work with any NPU having a QDR™ look aside interface. Multiple
devices including the QDR™ NSE can be connected to the same QDR™
interface. Each QDR™ NSE device may be point-to-point expanded up
to eight NSE devices.
