Problems solved by technology
[0004] The purpose of the present invention is to overcome the problem of data redundancy caused by repeated partial modifications in traditional cloud synchronization and the problem of too many requests to cloud servers due to frequent modifications, and to provide a differential cloud synchronization method based on fog computing mode, which can be used by users The fog service layer is added between the cloud service layer and the cloud service layer. For the synchronization request of the client, the fog server performs preprocessing to ensure that the final synchronization with the cloud minimizes data transmission and reduces the number of requests to the cloud server, optimizes the storage of differential synchronization and Operation efficiency, improve cloud service quality

Embodiment Construction
[0027] The technical solutions in the embodiments of the present invention will be described and discussed in detail below in conjunction with the drawings of the present invention. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] The basic idea of a differential cloud synchronization method based on the fog computing mode of the present invention is to add a fog service layer between the user layer and the cloud service layer, and perform preprocessing on the user's synchronization request to ensure that the final synchronization with the cloud is minimized. Streamline data transmission and reduce the number of requests to cloud servers. The fog service layer mentioned here is an intermediate computing platform between cloud and local designed based on the idea of fog computing, with computing and storage capabilities between cloud and local.

The present invention relates to a differential cloud synchronization method based on a fog computing model. A fog service layer is added between the user layer and the cloud service layer to process each client's synchronization request through the differential synchronization method. The user layer includes several users end, the fog service layer includes a fog server, and the cloud service layer includes a cloud server; the differential synchronization method includes: the user end uploads each modified difference data to the fog server for storage, and the fog server judges whether the stored data reaches a preset upper limit , if not reached, the fog server saves each difference data and updates the data; if reached, the fog server uploads the final difference data to the cloud server, and the cloud server reconstructs the cloud file based on the final difference data, so that the cloud server end file Be consistent with the latest files on the client side. The method of the invention can optimize the storage and operating efficiency of differential synchronization, and improve the quality of cloud services.
Description
technical field [0001] The invention belongs to cloud synchronization technology in the field of cloud computing, and in particular relates to a differential cloud synchronization method based on a fog computing mode. Background technique [0002] As a new concept of cloud computing extension, cloud storage is a development trend of current storage methods. With the continuous development of network bandwidth, the application of cloud storage will become more common in the future. Cloud storage provides users with a variety of services, the most representative of which is cloud synchronization technology. Specifically, cloud synchronization technology is aimed at the data stored in the cloud and the user's local data, so that no matter when and where the user makes any changes to the local data, the cloud data can also be updated in time. The most critical point in cloud synchronization is to minimize the amount of data transmission during cloud synchronization, because mos...
