Problems solved by technology

[0002] Due to the limited bandwidth resources of servers in the cloud computing peer-to-peer network and CDN (Content Delivery Network, Content Delivery Network), the rate of content distribution is restricted, and there is currently no certain mechanism to distinguish between scarce data and popular data, which may cause As a result, the truly scarce content cannot be replenished in a timely manner, while the popular content is more abundant, resulting in a serious imbalance in the allocation of resources in the system

Abstract

The invention discloses a method, system and implicit content server for data transmission on the basis of cloud computing. The method includes: the implicit content server receives conditions of files owned by common nodes of common node periodical reports in a network; resource index of each data block of each file is calculated according to the conditions of the files owned by the common nodes; bitmap information corresponding to most scare front K data blocks of each file is set as visual common nodes according to the resource index, bitmap information corresponding to the surplus data blocks is set as invisible common nodes, and the value of K is adjusted periodically and dynamically according to current bandwidth using conditions of the implicit content server and file bandwidth occupancy thresholds configured for each file; and bitmap information of each file in the implicit content server is respectively issued to the common nodes in the network so as to enable the common nodes to request the data blocks from the implicit server according to the issued bitmap information.

Description

technical field [0001] The present invention relates to the technical field of network applications, in particular to a cloud computing-based data transmission method, system and implicit content server. Background technique [0002] Due to the limited bandwidth resources of servers in the cloud computing peer-to-peer network and CDN (Content Delivery Network, Content Delivery Network), the rate of content distribution is restricted, and there is currently no certain mechanism to distinguish between scarce data and popular data, which may cause As a result, the truly scarce content cannot be replenished in a timely manner, while the popular content is more abundant, resulting in a serious imbalance in the allocation of resources in the system. Contents of the invention [0003] A technical problem to be solved by the present invention is to provide a data transmission method, system and implicit content server based on cloud computing, which can guarantee the downloading o...
