Abstract

The invention provides a data transmission method. The data transmission method comprises the steps of obtaining to-be-sent data; processing the to-be-sent data to obtain a first parameter which characterizes the to-be-sent data; sending the first parameter to at least one data node; receiving returning data for the first parameter from the data node, wherein the returning data indicate at least one part of the to-be-sent data already existed in the data node; generating a data packet based on the returning data, wherein the data packet does not carry the at least one part of the to-be-sent data already existed in the data node; and sending the generated data packet to the data node. The invention further provides a data receiving method, a data transmission system and a data receiving system.

Description

technical field [0001] The present disclosure relates to a data transmission method, a data reception method, a data transmission system and a data reception system. Background technique [0002] With the continuous improvement of social informatization level and the rapid development of Internet technology, more and more information is stored in the form of unstructured data and transmitted through the network in the form of data. As the amount of data continues to accumulate, data transmission with large amounts of data and long connections often occurs. In this case, if all the data is transmitted without filtering, it will lead to the problem that the network bandwidth is relatively high and the utilization rate is not high. Contents of the invention [0003] One aspect of the present disclosure provides a data transmission method, including: acquiring data to be sent. The data to be sent is processed to obtain a first parameter characterizing the data to be sent. s...
