  • Packet switch control with layered software
    Patent number: 6400925
    Abstract: A communications satellite (201) has an on-board high speed packet switch for switching transmitted data packets. The packet switch (502) is part of a processor subsystem (501) which also includes a number of demodulators (5031 to 503n) demodulating signals received from an uplink downconverter. All of the processors in the processor subsystem (501) are organized into a loosely coupled, distributed, architecture of general purpose computer modules (601) and digital signal processor modules (602) having both primary and redundant processors and being connected to each other by dual redundant PCI buses. Software and firmware is layered and distributed redundantly over the processor modules (601, 602).
