ABSTRACT:
In a node failure detection technique at least one supervisory data processing node periodically transmits a receipt acknowledge data packet to each other data processing node. The supervisory data processing node determines a data processing node has failed upon failure to receive a return acknowledge data packet. This acknowledge data packet preferably includes health data concerning its current health operating status. The supervisory data processing node sends a reset data packet to any failed data processing node determined. If the reset does not return the data processing node to normal operation, then routing data at neighboring data processing nodes is altered to route data packets around the failed node.
