The NL3180EGLQ device is a knowledge-based processor, which enable network awareness and provide the ability to leverage knowledge about the overall network. This knowledge-based processor provide efficient and rapid decision-making in the processing of packets, or the pieces of information flowing through the network.

These devices integrate a glue-less interface to ASICs, FPGAs and Network Processors through two QDR™ II SRAM ports. These devices interface seamlessly to the network processors that follow the Network Processor Forum LA-1 specification including Intel's IXP2400, IXP2800 and IXP2850.

The device uses information contained in single or multiple logical databases that store packet classification rules and/or IP addresses. Its primary applications are for packet classification, policy enforcement, state-based routing, packet forwarding, MPLS searches, MAC address searches and/or QoS enforcement for differentiated services in Core, Edge, Metro and Enterprise networking applications.

By providing knowledge-based processing for packets, these knowledge-based processors enable network service providers to offer more advanced functionality at wire-speed performance for the Internet, such as Voice over Internet Protocol, or VoIP, Virtual Private Networks, or VPNs, streaming video and audio, Internet Protocol version Six, or IPv6 and secure financial transactions.
