Abstract

An embodiment of the invention discloses a data transmission method, device and system. The method includes steps: a transmitter node transmits task data to a receiver node and detects quantity of the data transmitted; if the quantity reaches a preset threshold, a progress query request is transmitted to the receiver node; according to receiving progress information which the receiver node returns in response to the progress query request, data fragments not transmitted are determined and are transmitted to the receiver node. The receiving progress information includes data fragment identifiers received by the receiver node. The data transmission method, device and system has the advantages that data can be transmitted or received quickly, efficiently and accurately, good basis of data transmission services is provided for service publicity, capacity expansion, data transfer and the like and time is greatly saved.

Description

technical field [0001] The present invention relates to the technical field of network transmission, in particular to a data transmission method, device and system. Background technique [0002] Data transmission refers to the transmission of data between the sending node where the data source is located, each intermediate node, and the target node through a link composed of one or more node peers according to the corresponding transmission protocol. Common data transmission includes data download, point-to-point data transmission, etc. [0003] The current common data transmission architecture generally includes: seed is the sending node, which stores the original data and is used for data transmission; peer is the receiving node, which is used for data reception and can send the received data to other peers at the same time ; The controller is the scheduling node of the chain distribution algorithm, which is used for the scheduling of each peer. The controller can perfor...
