Embodiment 1

[0031] Elastic cloud distribution method based on peer-to-peer architecture, based on such as figure 1 The distribution device shown includes a distribution node cluster 1 and a cache system 2 , the distribution node cluster 1 is composed of a plurality of distribution nodes 3 , and the distribution nodes 3 include a distribution scheduling module 31 , a cache client 32 and a multi-protocol transmission module 33 . The function of the distribution scheduling module 31 is to accept the transmission request from the user's distribution transmission client 4 and complete corresponding processing. The cache client 32 is an interface for interacting with the cache system 2 . The multi-protocol data transmission module 33 is used to be compatible with data distribution methods of various data sources.

[0032] When the client initiates a request to distribution node A, it requests data resource R. When distribution node B also receives a request for data resource R.

Abstract

The invention relates to a peer-to-peer architecture based elastic cloud distribution method. The stability and expandability of distribution nodes are improved by functionally dividing the distribution nodes into distribution center nodes and peer nodes methodically and forming a hybrid peer-to-peer network. Meanwhile, different conditions of whether a cache system hits the target are distinguished, and the method comprises the steps of basic distribution and extended distribution, thus improving the data distribution efficiency. The method has the advantages that large-scale distribution service can be supported, the data distribution speed can be increased, the problems of network bandwidth of a single data source and server performance bottleneck are broken through, the network access quality is optimized, and the method has a better application value.

Description

technical field [0001] The invention mainly relates to an elastic cloud distribution method based on peer-to-peer architecture. Background technique [0002] With the advent of the era of massive data explosion, data sharing and distribution are facing new challenges: the data that needs to be saved is increasing at a rate of terabytes every day, the storage capacity of the data changes greatly, and an elastic expansion mechanism is required, and it is difficult for data distribution to break through a single Point the bottleneck. [0003] NASA (National Aeronautics and Space Administration) EOS system is a remote sensing data integration and sharing system. Although EOS has done a good job in the integration and storage of remote sensing data, it still adopts the traditional single-point distribution scheme in the distribution management of remote sensing data. Meet users' requirements for rapid distribution of remote sensing data. [0004] Content Delivery Network (Conte...
