Abstract
In a distributed computer network having a large number of intercommunicating distributed nodes and a smaller number of control nodes in which each distributed node reports status information to a particular one of the control nodes, a method is provided for guaranteeing that at least one control node receives a status message from a distributed node despite the unavailability of the particular control node to which the distributed node normally sends its status messages. Each distributed node associates a serial number and time stamp and an identification of itself with each message it originates, and each distributed node retains copies of the messages. Should a distributed node be unsuccessful in transmitting to its normal control node it attempts to transmit to other control nodes until it transmits successfully. A control node assigned to assume the functions of an failed control node requests a distributed node formerly associated with the unavailable control node to resend all messages it originated within a period of time sufficiently long that at least all messages sent to the failed control since its failure are resent. Since replicate messages may be sent to a plurality …
