The NSE-1 consists of the following components:

Reduced instruction set computing (RISC) microprocessor

The NSE-1 uses an RM7000 microprocessor that operates at an internal clock speed of 262 MHz.

Parallel eXpress Forwarding processor

The Parallel eXpress Forwarding (PXF) processor enables parallel IP multipacket processing functions, working with the routing processor to provide accelerated packet switching, as well as accelerated IP Layer 3 feature processing.
