Abstract
A computer architecture for providing enhanced reliability while mitigating the high costs of total redundancy. The HUB and Street architecture couples a plurality of commonly shared busses called streets with a plurality of smart switching elements called HUBs. The streets are busses for transferring data between HUB elements. The HUB elements are capable of directing data across the street structures and deliver said data to a desired destination. The system designer can either increase or decrease the number of HUB elements and streets to either increase or decrease the reliability and cost of the particular computer system. In addition, the HUB elements have a built in priority scheme for allowing high priority data to be transferred before low priority data. Finally, the HUB elements have the capability of automatically detecting faults within the system and can redirect the data around said faults. This automatic rerouting capability is the subject of the present invention.
