Point-to-point network-based data storage method and device, medium and terminal equipment

Abstract

The invention belongs to the technical field of computers, and particularly relates to a point-to-point network-based data storage method and device, a computer readable storage medium and terminal equipment. The method comprises the steps that a source node divides data to be stored into data fragments, and determines the backup number of the data fragments; the source node determines a first-level storage node corresponding to the sth data fragment, and sends a data storage request to the first-level storage node; the nth-level storage node determines an (n + 1) th-level storage node corresponding to the sth data fragment, and sends a data storage request to the (n + 1) th-level storage node; after the (n + 1) th-level storage node receives the data storage request, the (n + 1) th-levelstorage node downloads and stores the sth data fragment from each target node, adds the node identifier of the (n + 1) th-level storage node into the storage node set, and subtracts one counting unitfrom the counting value until the counting value is 0, thereby reducing the occupation of source node bandwidth resources.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a data storage method, device, computer-readable storage medium and terminal equipment based on a peer-to-peer network. Background technique [0002] A peer-to-peer (Peer-to-Peer, P2P) network is a network architecture mainly composed of a large number of peer nodes. The relationship between different nodes is equal, and resources can be transmitted to each other. In the process of resource transmission, each node will not only obtain the required resources from other nodes that have resources in the peer-to-peer network, but also distribute the downloaded resources to each node that needs the resources in the peer-to-peer network, thus extremely It greatly improves the transmission efficiency of resources in the network. [0003] In storage in a peer-to-peer network, in order to ensure data security, it is necessary to increase the redundancy of the data. Often, m...
