The high-speed switching section of the RSP7000 communicates with and controls the interface
processors on the high-speed CxBus. This switching section decides the destination of a packet and
switches it accordingly. The RSP7000 uses a 16-million-instructions-per-second (mips) processor to
provide high-speed, autonomous switching and routing.
