Embodiment Construction

[0106] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0107] In the present invention, the source data terminal stores the source data on the storage nodes on the network to realize distributed storage of data. Before storing the data on the storage nodes, the source data terminal encodes the source data in segments to generate multiple pieces of data. When data needs to be downloaded, the source data terminal downloads the corresponding data slices from the storage node, decodes the downloaded data slices, merges and restores the completed source data.

Abstract

This invention provides a distribution storage download system, a device and a method for network data, in which, said system includes: a source data terminal used in carrying out linear coding to source data to generate multiple data slices and carrying out linear de-coding to the data slices of the source data to resume the source data, a storage node connected with said source data terminal to download and store said data slices and an index server connected with the source data terminal and storage node for managing the information of the data slice and network information of the nodes to control the terminal or nodes to download data slices of the source data.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a distributed storage and download system, device and method for network data. Background technique [0002] With the development of communication networks and the continuous enhancement of terminal capabilities, users can use more and more types of data. In addition to basic address books, call records, and SMS and MMS records, it also includes ring tones, pictures, videos, and games. multimedia data. Rich data applications require data to be stored outside of local storage. However, non-local storage has higher security requirements for data storage and transmission. [0003] figure 1 It shows a network structure for implementing data storage in the prior art, user data is stored in a data server, and the data server allocates a piece of storage space for each terminal. When the terminal needs to download data, it accesses the data server through the network to downloa...
