  • Patent number: 8429123
    Abstract: Synchronization architectures, methods, systems, and computer readable media are described. In one embodiment, a synchronization session is initiated between a first data processing system and a second data processing system. First data, representing changes to a first data class, is transmitted from the first data processing system to the second data processing system. Second data, representing changes to a second data class, is transmitted from the first data processing system to the second data processing system. Transmission of the second data begins before transmission of the first data is complete. The first data may comprise structured data such as contacts information, to do information, calendar information, or web browsing bookmarks.

  • Publication number: 20130006929
    Abstract: Among other things, techniques and systems are disclosed for providing sync server process. Processing data sync sessions includes processing a request to initiate a sync session from one or more clients to update one or more data records that include one or more data items. The one or more clients are selectively identified as one of a trusted client and an untrusted client based on one or more properties of the sync session, wherein the trusted client is configured to support all dataclasses defined by the server. The one or more clients are detected as being configured to support field level differencing that sends changed data items only for the one or data records or record level differencing that sends all of the data items included in the one or more data records.

  • Patent number: 8224918
    Abstract: Among other things, techniques and systems are disclosed for syncing data between a client device and a server. Synchronizing data includes initiating a sync session by negotiating a sync mode between a client device and a server for each of one or more dataclasses. A status code is generated based on a result of the negotiating. Based on the generated status code, the client device and the server exchange one or more data items to be updated for the one or more dataclasses using the negotiated sync mode for each dataclass. The exchanged one or more data items are updated at the client device or the server. The updated one or more data items are committed at the client or the server.

  • Patent number: 8112537
    Abstract: Among other things, techniques and systems are disclosed for providing trickle syncing. In one aspect, a system includes a data repository to store one or more data records and a server in communication with the data repository. The server is designed to access the data repository in response to a user request to perform at least one of the following: access the one or more data records, add a data record, and modify the one or more data records. The system also includes a client application in communication with the server. The client application is designed to receive the user request through a client process; encapsulate a protocol that provides communications between the client process and the server; and forward the received user request to the server using the encapsulated protocol.
