  • Publication number: 20250062922
    Abstract: Techniques for implementing highly available, verifiable, and decentralized WebSocket subscriptions for a blockchain network are provided. In one set of embodiments, these techniques include maintaining, by the replicas of the blockchain network, identical copies of the metadata (i.e., artifacts) for the network's WebSocket subscriptions and digitally signing, by the replicas, all subscription-related responses. With this approach, the subscribers of the WebSocket subscriptions can verify that the responses they receive are authentic by verifying the included signatures. Further, because the subscription artifacts are maintained as shared state across the replicas, there is no single point of failure or centralized trust for the subscriptions, resulting in improved fault tolerance and security.

  • Patent number: 10248557
    Abstract: The disclosed computer-implemented method for delayed allocation in cluster storage may include (i) delegating, to a node attached to a storage cluster including one or more storage devices that include a group of allocation units, a subset of allocation units on the storage cluster to be held as a delayed allocation pool, (ii) receiving, from the node, a request to allocate allocation units on the storage cluster, (iii) deducting the number of allocation units from available allocation units in the delayed allocation pool, (iv) satisfying the allocation request by allocating allocation units not in the delayed allocation pool before allocating allocation units included in the delayed allocation pool, and (v) recalculating, based on the number of allocation units in the delayed allocation pool used to satisfy the allocation request, the number of available allocation units in the delayed allocation pool. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 8655851
    Abstract: A method for file lock recovery in a distributed computer system. The method includes executing a distributed computer system having a plurality of nodes comprising a cluster, and initiating a network file system server migration from one node of the cluster to a different node of the cluster. A migration count is incremented, wherein the migration count is stored at each of the nodes comprising the cluster. File lock services are paused at each of the nodes comprising the cluster. The network file system server migration is completed at the different node of the cluster. The migration count is then decremented in response to the completion. File lock services are then resumed at each of the nodes comprising cluster.
