  • Fault-tolerant method of communicating between processes in a multi processor system by keeping track of the current node location of messages
    Patent number: 5404501
    Abstract: A method for communicating between processes in a data processing system comprising a plurality of processor hosts each coupled to a network and a plurality of processes resident on different ones of said processor hosts, wherein messages are transmitted from one process to another in a logical ring. A message-holding queue is maintained at any host originating a message transmission, and it contains a copy of the message, an identifier of the initiating processor host, and an identifier of the target processor host. A forward notification message is returned to the originating host from a forwarding host when the forwarding host relays the message to another host, and an identical forward notification message is returned to the originating host by the target host when it receives the message.
