18M Network Search Engine (NSE) with Dual LA-1 Interface (QDR™II Interface Compliant)
Introduction
With the expanding Internet, all levels of the network must become faster. This requires high-speed packet searches, which are essential for routing, but also necessary for higher-level functions such as Quality of Service (QoS) support and access control. To meet this need, IDT has developed network search engines that accelerate packet processing at OC-192 data rates and beyond. www.DataSheet4U.com
