ABSTRACT:
A method and hardware apparatus provide a fault tolerant and flexible multi-stage network addressing scheme for transmitting a message with a header containing control bits for selecting from various destination checking functions to be performed. Upon arrival of the message at a node, destination checking is performed or not in response to the massage's header. If destination checking is not performed, or if destination checking is performed and indicates that the node is the desired destination for the message, the message is accepted. If destination checking is performed and indicates that the node is not the desired destination for the message, the message is rejected. Destination checking is disabled during address assignment, broadcasting and multi-casting, and replaced with one's complement-based verification of the sending node.
