Cisco NSE-1 800-05272-12 7200 VXR Network Service Engine I w 128MB
The network services engine maintains and executes the system management
functions for the Cisco 7200 VXR routers. The NSE-1 also shares the system memory and
environmental monitoring functions with the I/O controller. Its performance is greater than that of the
network processing engines because of the Parallel eXpress Forwarding (PXF) processor. The PXF
processor works with the routing processor to provide accelerated packet switching, as well as
accelerated IP Layer 3 feature processing.
