Problems solved by technology

[0004] The purpose of the present invention is to propose a content hierarchical storage architecture of a carrier-grade P2P network and a content delivery method for fragmented peer-to-peer transmission, which is suitable for the development of carrier-based P2P content sharing applications and can meet the stability requirements of carrier-grade networks. , high efficiency, high quality, and cost savings as much as possible, so as to solve the problems of low efficiency and missing content of the existing distributed storage architecture, and "uneven hot and cold" content storage and distribution

Embodiment Construction

[0025] The P2P content hierarchical storage architecture described in the present invention is as follows: figure 1 shown. In this improved content storage architecture, three types of nodes with P2P interaction capability are included, namely, content storage central node, content storage edge node and content storage terminal node. Among them, all the original data that has passed the review and the content is legal are stored on the storage node of the content center. According to distribution needs, the content on the content storage central node is distributed to the content storage edge nodes irregularly. The third type of nodes inside the dotted ellipse are content storage terminal nodes. This type of node has the weakest performance and storage capacity, and the access bandwidth is not high, and it stays on the network irregularly and for an indefinite length of time.

[0026] Generally, content storage terminal nodes only conduct P2P communication with other content...

Abstract

The invention relates to a content staging memory storage and transmission method of a communication level P2P network, wherein all sharing content is stored on three kinds of nodes with P2P alternation capability, namely: a content storage central node, a content storage fringe node and a content storage terminal node. According to the invention, the content is downloaded in priority order of the content storage terminal node, the content storage fringe node and the content storage central node. The scheme of the invention satisfies the requirement of the communication level network on stability, high efficiency, high quality and saved cost, thereby solving the problems of lower efficiency of prior distributivity storing frame, deficient content, 'uneven cold and hot' of content storage and distribution.

Description

technical field [0001] The invention relates to a content hierarchical storage and transmission method of a telecommunication-level P2P network. Background technique [0002] At present, the most widely used field of P2P is the field of resource sharing represented by downloaded files. Various file sharing software emerge in an endless stream, such as BitTorrent, eMule, KazaA, domestic KuGoo, PP Dotton, etc., among which BitTorrent and eMule are the most used. widely. [0003] All of the above applications adopt a distributed storage method, that is, all shared files are stored scatteredly on the terminal nodes, some of which are complete, and some of which are missing certain fragments. Due to the "selfish" behavior in the field of P2P content sharing, that is, many users do not share with others after obtaining complete files, resulting in the absence of fragments of many contents on the Internet, so that complete files cannot be formed. In addition, it is easy to find d...
