Data acquisition method and device, computer equipment and storage medium

Abstract

The invention relates to a data acquisition method and device, computer equipment and a storage medium. Based on a data acquisition method, a terminal requests a scheduling system to download target data, the scheduling system allocates a plurality of nodes storing the target data to the terminal and sends link addresses of a plurality of to-be-accessed nodes to the terminal, the terminal can generate a plurality of downloading requests according to the link addresses of the to-be-accessed nodes, each downloading request being used for making a request to download partial data in the target data, and the terminal sends each downloading request to the target node in the plurality of to-be-accessed nodes according to the link address, that is, the terminal can obtain partial data in the target data from the plurality of to-be-accessed nodes until the terminal obtains the complete target data. By downloading the target data through the plurality of to-be-accessed nodes, the data pressure of downloading the data just through one node is reduced, the downloading efficiency is improved, the plurality of to-be-accessed nodes comprise a home node, the terminal can use the idle bandwidth of the home node to download the data, and the network traffic of a backbone network is reduced.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a data acquisition method, device, computer equipment and storage medium. Background technique [0002] When a user uses a terminal to download the required file resources, in order to respond to the user's data request as soon as possible, the CDN node near the terminal is usually used to provide the user with the file resource required by the user. However, when the user requests a large amount of data When downloading data through a single CDN node, the user needs to wait for a long time, and the complete file resource cannot be provided to the user quickly. For example, when the user requests to play a video with a large amount of data, the user needs to wait for the cache to play. It cannot bring a good visual experience to the user. At the same time, for the provider of the file resource, in order to allow the user to download the file resource c...

[0002] When a user uses a terminal to download the required file resources, in order to respond to the user's data request as soon as possible, the CDN node near the terminal is usually used to provide the user with the file resource required by the user. However, when the user requests a large amount of data When downloading data through a single CDN node, the user needs to wait for a long time, and the complete file resource cannot be provided to the user quickly. For example, when the user requests to play a video with a large amount of data, the user needs to wait for the cache to play. It cannot bring a good visual experience to users. At the same time, for file resource providers, in order to allow users to download file resources conveniently, it needs to spend more cost to use CDN nodes to cache the file resources provided by them.
