ABSTRACT:
A failure notification system for a system including a plurality of processors connected by a common path through individual node stations. The failure of a data processor is detected by the associated node station by noting the cessation of clock pulses from the processor. When a data frame from a remote processor is destined for the failed processor and is received by the node station for the failed processor, the latter node station transmits a failure notice frame onto the common path. The destination address and source address of the failure notice frame are the reverse of those addresses in the data frame destined for the failed processor.
