NITROX® DPI L7 Content Processor Family


The NITROX® DPI processor family includes the CN18XX and CN17XX that provide the most advanced hardware acceleration available for inline, NIC and co-processor Layer 7 content processing. The CN18XX supports completely processor-less mode or can be coupled to OCTEON®, x86, MIPS, PowerPC or other general purpose processors, enabling intelligent, deep packet inspection in next-generation networking and wireless applications from 2 to 40 Gbps performance.

The CN18XX processor family integrates Inline interfaces (Up to four XAUI and up to 8 SGMII), up to two PCI Express Gen 2 x4 or x8 I/Os along with the most advanced deep packet inspection engines, Hyper Finite Automata Thread Engine (HTE), to deliver the highest performance, low latency processing of very complex regular expression rules.

The CN17XX processor family runs in coprocessor mode and supports PCI Express Gen 1 x4 or x8 I/Os. For new designs we recommend using the CN18XX as it supports a superset of CN17XX features.

NITROX DPI processors are targeted for a wide range of applications including application recognition, protocol analysis, flow statistics, application level firewalls, intrusion prevention (IPS), gateway anti-virus, unified threat management and content-based QoS in routers, switches, appliances and services blades.
