Problems solved by technology

Furthermore, the client device must try to wait for the update process in the local data store to complete before forwarding the local identifier map to the host device, which may cause slowness in the update process due to the characteristics of applicable pervasive devices. considerable delay
Finally, current synchronization protocols do not allow for the implementation of traffic delivery with a large amount of update traffic in a synchronization process originating from a host device rather than a client device

Embodiment Construction

[0016] The embodiments of the present invention provide a method, system and computer program product for protocol optimization data synchronization. According to an embodiment of the present invention, while retrieving the retrieval of the server update block, the server update to the client during the data synchronization for the public application can be stored in the client data storage. Moreover, a single server update to a client for full synchronization can be split into multiple update exchanges of a subset of server updates between the server and the client. Finally, during the data synchronization process, the pre-allocated temporary local identifier can be mapped to the data object on the server side, so that the interruption of the synchronization process can be restored without restarting the synchronization process.

[0017] By executing the server update to the client while retrieving the server update block, the slow, serial processing characteristics of the tradit...

Abstract

Embodiments of the present invention address deficiencies of the art in respect to data synchronization and provide a method, system and computer program product for protocol optimization for client and server synchronization. In one embodiment a protocol optimization method for client and server synchronization can be provided. The method can include receiving server updates from a synchronization server, and applying each update to a client data store in parallel to requesting additional ones of the server updates from the synchronization server before completing the application to the client data store. In one aspect of the embodiment, receiving server updates from a synchronization server can include receiving server update subsets of a singular server update for a synchronization conversation from a synchronization server.

Description

Technical field [0001] The present invention relates to the field of data synchronization, and more specifically to the use of a synchronization framework to provide data synchronization services. Background technique [0002] The personal computer is no longer the most common tool through which users connect to a data communication network like the Internet. Now that computing is seen as truly ubiquitous, computer scientists and information technology experts have begun to rethink the services that are provided to meet the needs of mobile computing users. As a result, the research of pervasive computing has led to substantial changes in the field of network connectivity. "Pervasive computing" has been defined as involving any unconstrained computing device that is not physically limited to data communication networks. Therefore, pervasive computing devices not only involve wirelessly connected computers, but also portable computing devices, wearable systems, embedded computing s...
