ABSTRACT:
Systems and methods are provided for atomic single-failure non-blocking and double-failure non-blocking commitment protocols. The protocols may be used for a variety of transactions that involve two or more parties including an initiator of the transaction, a coordinator of the transaction, and one or more participants in the transaction. The participants notify the coordinator when they are prepared to commit the transaction. The coordinator then determines when to commit or abort the transaction. If the coordinator disconnects from one or more of the participants, the participants can resolve the transaction independently. Some embodiments also include a distributor that interacts with the coordinator and the participants to resolve the transaction. If one or more parties become disconnected from the coordinator or the distributor, the participants vote to determine whether to receive instructions from the coordinator or the distributor.
