Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the data transmission system in the cloud storage of the present invention includes a node organization and management module 1 , a data transmission module 2 and a data cache service module 3 . The node organization and management module 1 communicates with the data cache service module 3, and the data transmission module 2 communicates with the data cache service module 3.

[0022] The node organization and management module 1 is used to manage all online user nodes, and send the super node information in the online user nodes to the data cache service module 3 in real time, so that the data cache service module 3 can select a collaborative group node.

[0023] The data transmission module 2 is used to send the redundant storage data to the data cache service module 3 in real time.

[0024] The data cache service module 3...

Abstract

The invention discloses a data transmission system in a cloud storage, which comprises a node organization and management module, a data transmission module and a data caching service module, wherein the node organization and management module communicates with the data caching service module, and the data transmission module communicates with the data caching service module; the node organization and management module is used for managing all online user nodes and sending super node information among the online user nodes to the data caching service module in real time so that the data caching service module can select collaborative group nodes; the data transmission module is used for sending redundant storage data to the data caching service module; and the data caching service module is used for formulating a redundant storage data backup strategy according to the information of super nodes received from the node organization and management module and the redundant storage data received from the data transmission module. The data transmission system provided by the invention can provide the function of data transmission based on unreliable cloud storage service.

Description

technical field [0001] The invention relates to the fields of computer network and computer storage, and more specifically, the invention relates to a data transmission system in cloud storage. Background technique [0002] In the wide area network environment, distributed storage has its inherent advantages. Its main advantage is strong scalability and the use of edge servers to improve data transmission speed. In traditional distributed storage systems, the core method to improve system availability and reliability is to replicate and back up data blocks, and improve the stability of storage system services through global and effective redundant distribution of data. [0003] However, distributed distribution also has its own technical difficulties. Using free storage resources in the network as the edge storage server of the system solves certain problems to a large extent. However, most storage systems for personal use do not provide sharing. Moreover, the storage serv...
