Intel IXP2350 network processor

Intel IXP2350 network processor

The Intel IXP2350 network processor extends Intel's fully programmable architecture to new, lower cost/performance points for access and edge applications, including broadband access devices, wireless infrastructure systems, routers and multi-service switches.

To meet today's and tomorrow's demanding data plane performance requirements, the IXP2350 network processor provides a powerful, integrated control plane processor in the same chip. The high-speed core (up to 1.2 GHz) incorporates advanced I/O and memory features, enabling customers to eliminate an external control plane processor in many applications. Additional hardware-assisted features in the IXP2350 network processor increase performance and simplify development.
