The NSE-100 consists of the following components:
Reduced instruction set computing (RISC) microprocessor
•
The NSE-100 uses an RM7000 microprocessor that operates at an internal clock speed of 350 MHz.
Parallel eXpress Forwarding processors
•
The Parallel eXpress Forwarding (PXF) processors enable parallel IP multipacket processing
functions, and work with the Route Processor to provide accelerated packet switching, as well as
accelerated IP Layer 3 feature processing.
System controller
•
The system controller provides hardware logic to interconnect the processor, DRAM, and the system
backplane bus. The NSE-100 has one system controller that provides processor access to the two
midplanes.
•
Upgradeable memory modules
The NSE-100 uses a SDRAM SODIMM for providing code, data, and punted packet storage.
Generally, packets are stored in packet memory.
Cache memory
•
The NSE-100 has three levels of cache: primary and secondary cache that are internal to the
microprocessor with secondary unified cache for data and instruction, and tertiary, 2-MB external
cache.
Four environmental sensors for monitoring the cooling air as it enters, moves across the system
•
board, and leaves the chassis
