Data transmission method and device thereof

Abstract

The invention provides a data transmission method and a device thereof. The data transmission method comprises the following steps: setting configuration files corresponding to respective group identifiers ID in a cloud server; determining a target group identifier ID of a group of a calculation node when the calculation node needs to obtain target resource data; feeding target configuration files corresponding to the target group identifier ID to the calculation node via the cloud server, and obtaining a first P2P server with operator information as same as the self operator information of the calculation node via the calculation node according to operator information corresponding to respective P2P servers; and obtaining a communication address of the calculation node in which the target resource data is stored via the first P2P server, wherein the first P2P server and the calculation node belong to the same operator, so that the phenomenon that the operators hijack is avoided; the communication address of the calculation node in which the target resource data is stored can be successfully obtained from the first P2P server; the target resource data does not need to be downloaded from a CDN server, so that the bandwidth traffic of the CDN server is reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and more specifically, to a data transmission method and device. Background technique [0002] P2P (peer-to-peer) technology, or peer-to-peer networking technology, is a technology for directly exchanging data or services between different computers (also called computing nodes) without going through a relay device. Computing nodes in a peer-to-peer network have dual characteristics of client and server, and can serve as users and providers of services at the same time. The P2P network includes a P2P server and multiple computing nodes. The P2P network can include multiple groups. The P2P server in each group manages the corresponding resource data stored by each computing node in the corresponding group. If the computing node needs to obtain a certain resource data , first obtain the computing nodes storing the resource data through the P2P servers in the sa...

Problems solved by technology

[0004] In view of this, the present invention provides a data transmission method and device to overcome the phenomenon of operator hijacking in the prior art when cross-network access occurs, resulting in the inability to obtain the required resources from the corresponding computing nodes Data, only the corresponding resource data can be obtained from the CDN server, which increases the bandwidth traffic of the CDN server
