Method for constructing data quanta space in network and distributed file storage system

Abstract

The invention relates to a method for data quantity subspace construction on the network and a distributed document storage system. Through the distributed document storage system, user nodes use service nodes to choose and upload data documents onto usable user nodes in the network, and the distributed nodes are formed; after the user nodes upload the data documents or during the transmission of the data documents, the service nodes adjust the usable nodes in the whole backbone nodes network automatically to distribute tasks which are undertaken, the data documents that the user requests to upload or transmit are distributed and stored in the sharing space of a plurality of user nodes through copying the data documents, a plurality of sharing nodes are formed to be used by the user nodes to download or transmit the documents, so a data storage and transmit quantity subspace is formed in the network. The invention can realize stable, high efficient and opened enterprise-level distributed storage application.

Description

technical field [0001] The invention relates to a method for constructing a data quantum space on a network and a distributed file storage system, in particular to an internet-based, enterprise-level distributed file storage system and a method for constructing a data quantum space on the network. Background technique [0002] "Peer-to-Peer" peer-to-peer Internet technology (peer-to-peer network technology) allows users to directly connect to other users' computers for file sharing and exchange. It is also useful in work and other aspects. In fact, "Peer-to-Peer" is not a new network technology that was extended after the emergence of the Internet. The development is not as popular as it is today, and the network construction (such as bandwidth, processing power) and related hardware equipment cannot meet the needs of "Peer-to-Peer". Many intermediate products are derived. [0003] It can be seen that a remarkable feature of "Peer-to-Peer" is that it has changed the exist...

Problems solved by technology

However, the "Peer-to-Peer" network system of the above-mentioned prior art does not have a uniform data distribution and redundancy management mechanism, and user behavior is uncontrollable, for example, there is a problem that the controllability of user uploaded files is not strong. Problem, when the user is not online, the upload / download of files is generally not possible

Moreover, the "Peer-to-Peer" network system of the above-mentioned prior art also has defects in aspects such as network utilization efficiency (especially search efficiency), and the network utilization efficiency is low.

[0006] In addition, there are still some "centralized Peer-to-Peer network" structures in the prior art. For the "hot spot" nodes sharing files in the "Peer-to-Peer" network system of these structures, it is easy to request sharing Too many nodes will slow down the transmission speed and reduce the search efficiency, and it is also easy to cause node failure due to too many nodes requesting connection, and when the node fails, it will easily cause data loss, resulting in incomplete data. Therefore, the stability of the system is poor

[0007] In particular, the "Peer-to-Peer" network system in the prior art actually shares files, and does not propose a method for transferring large files. concept; so the existing system cannot provide real "big file" transfer

For the transmission of large files, the existing network structure has a data transmission bottleneck
