NSE-1 Description and Overview
This section contains information about the network services engine components and the system
management functions. 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.
The NSE-1 consists of two modular boards: the processor engine board and the network controller board.
It is keyed so that it can be used only in the Cisco 7200 VXR routers.
