    摘要: A distributed system includes full and partial replicas of a set of data items that may be inserted, modified, or deleted by any replica. Replicas may occasionally synchronize with other arbitrarily chosen replicas to learn about updates. A replica's knowledge includes of one or more knowledge fragments, where each fragment indicates a set of items. A type of knowledge fragment, called a star knowledge fragment, contains versions associated with all items in the system. Star knowledge fragments are compact because the set of items stored at a replica need not be explicitly listed. Once all replicas know of all updates in the system, partial and full replicas will have the same compact star knowledge fragment.

    摘要: A distributed system synchronizes replica devices with respect to items that may be inserted, modified, or deleted by any of the replica devices. Replicas may synchronize with other replicas to learn about updates to items. Each replica device may include a high-fidelity replication platform and/or a low-fidelity replication platform. The low-fidelity replication platforms may synchronize low-fidelity versions of items among the replica devices, and the high-fidelity replication platforms may synchronize high-fidelity versions of items among the replica devices. Each replica device may include a fidelity manager that copies high-fidelity versions of items from the high-fidelity replication platform, generates low-fidelity versions of the items from the high-fidelity versions of the items, and adds the low-fidelity versions of the items to the low-fidelity replication platforms. The fidelity managers may further integrate changes made to low-fidelity versions of items into the corresponding high-fidelity versions of the items.

    摘要: A hierarchical system is disclosed for synchronizing partially-replicated collections that provides guaranteed paths of information to all replicas in a collection. Each partial replica is assigned a parent replica to act as a proxy on its behalf, and with which the replica synchronizes regularly. Each parent replica is responsible for one or more child replicas. Parent replicas have filters which are either the same as, or more inclusive than, their child replicas, and parent replicas thus store and synchronize all objects that are of interest to their one or more child replicas.

    摘要: A protocol for replicating replicas in a sync community. Each replica maintains a knowledge that represents changes that the replica is aware of. Each replica does not typically maintain knowledge about other replicas. The protocol includes messages that include knowledge about changes on the various replicas. Using the knowledge, the replicas can enumerate changes and send the changes using asynchronous messages that do not need to be received in any particular order. The protocol enables filters to ensure that a valid replication is possible using a minimum knowledge argument. The protocol also enables replicas to partially replicate using filtered knowledge.
