Abstract (en)

[origin: WO9859519A2] A new asynchronous message processing system and method are provided in which a process is completely defined by a state and a type. Incoming messages received by a network node are stored in an input message queue and are handled in sequence in the order they arrive, and outgoing messages are stored in an output message queue and are transmitted in sequence in the order they are generated to a destination network node. Incoming messages addressed to a process are handled by invoking a particular message handling application code which runs to completion, and which may modify the process state. Process state modifications are atomic in the sense that they either completely happen or do not happen at all; partially implemented process state modifications are undone.
