Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] figure 1 It is a flowchart of the modified Past system node processing insert message in the present invention, and the specific process includes:

[0034] 101) After receiving the insert message, the node of the Past system extracts the file to be inserted from the insert message.

[0035] 102) The node inquires whether the local file system has stored the same file as the file ID to be inserted. If it already exists, go to 103; otherwise, go to 104;

[0036] 103) Compare the version of the inserted file with the same file with the locally stored ID, and judge whether the version of the inserted file is the latest, if it is the latest, then go to 104; otherwise go to 105.

[0037] 104) The Past system node stores the inserted file in the...

Abstract

The invention provides a file storing method and a file storing system based on partitioning strategies. Data blocks in the method are stored in a Past sub system, and the method concretely comprises the following steps that 101, user files to be stored are divided into a plurality of data blocks, and meanwhile, metadata of maintenance files, file partitioning and file access relevant information is created; and 102, all data blocks and the metadata are respectively used as files to be stored in the Past sub system optimized by a client, wherein the optimized Past sub system is a Past sub system added with deletion and updating operation, the data blocks have the same size, and the metadata structure concretely comprises file names, all file partitioning names, file size, last file modification time and last file access time. The method and the system provided by the invention have the advantages that high expandability, high availability and high safety of a Past file storing system are inherited, and in addition, the unnecessary bandwidth waste and the response time prolonging during the modification and reading operation on large files are avoided.

Description

technical field [0001] The invention relates to the technical field of distributed storage, in particular to distributed storage based on structured P2P technology and its application, in particular to a file storage method and system based on a block strategy. Background technique [0002] With the global coverage and promotion of 3G technology and the emergence of operating systems such as IOS and Android, mobile smart terminals are rapidly expanding in the market, and the corresponding application and research based on P2P technology has once again attracted everyone's attention. [0003] Among the many applications based on P2P technology today, the social network based on P2P technology is undoubtedly a research hotspot. Among them, most of the P2P-based social network applications are built on Past. Past is an open source application based on the structured P2P technology-Pasty to realize redundant storage of files. The file stored in Past will be completely copied K...
