  • SELECTIVE ACKNOWLEDGEMENT FRAMEWORK FOR HIGH-PERFORMANCE NETWORKS
    Publication number: 20230370203
    Abstract: According to examples, a selective acknowledgement framework may be implemented within a communication system for efficient communication of acknowledgement packets. A plurality of data packets generated from a message may be transmitted as a segment of data packets to a receiver which generates an acknowledgement packet for the segment of data packets. A compact format of acknowledgement (ACK) or negative acknowledgement (NACK) for the segment of data packets may be implemented in the acknowledgement packet via bits of a selective acknowledgement bit vector. Based on the other values also conveyed in the acknowledgement packet, the transmitter may identify those data packets that were properly received and the data packets that need to be re-transmitted.

  • In-place garbage collection of a sharded, replicated distributed state machine based on supersedable operations
    Patent number: 11055184
    Abstract: A log unit provides a shared log for recording updates on data objects. Garbage collection is performed locally and in-place by the log unit. In a marking portion of the garbage collection process, the log unit identifies and marks log entries that record supersedable updates. In a deallocation portion of the process, the log unit deallocates at least portions of the marked log entries that contain supersedable updates.

  • In-place garbage collection of a sharded, replicated distributed state machine based on mergeable operations
    Patent number: 10877881
    Abstract: A log unit provides a shared log for recording updates on data objects. Garbage collection is performed locally and in-place by the log unit. In a marking portion of the garbage collection process, the log unit identifies and marks log entries that record mergeable updates. In a deallocation portion of the process, the log unit merges one or more mergeable log entries and deallocates at least portions of the merged log entries.

  • Direct access to object state in a shared log
    Patent number: 10649981
    Abstract: A shared log in a distributed system provides for direct access to the most current data state of an object stored in the shared log. Directly accessing the data state of an object obviates the need for a client to replay all the transactions stored in the shared log made on the object.

  • Fine-grained conflict resolution in a shared log
    Patent number: 10635541
    Abstract: In accordance with disclosed embodiments, a shared log system includes a sequencer to verify transactions that comprise a source object and one or more members of the source object (source data objects), a target object and one or more members of the target object (target data objects), and a snapshot time reference. The sequencer verifies transaction using the snapshot time to determine whether the data states of the source data objects at the time of the snapshot time represent their most current data state in a shared log.
