Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] An embodiment of the present invention provides a method for downloading data, which can be used in a data transmission system, and the data transmission system can include a CDN cluster, a dispatch center, and multiple home nodes. Among them, the CDN cluster can be a conventional CDN cluster containing multi-layer nodes in the prior art, and its edge nodes can be used to receive data acquisition requests from user terminals, and respond based on data stored locally or obtained by returning to the parent; A node can be a device node that transmits data based on a home broadband network, such as a TV box, a smart speaker, a home computer, etc., which can have certain data storage functions and data transmission functions. A home n...

Abstract

The invention discloses a data transmission method and a data transmission system, and belongs to the technical field of CDN (Content Delivery Network). The method comprises the following steps: an edge node receives a target data collection request sent by a target terminal; the edge node triggers the dispatching center to query a target home node corresponding to the target data; the dispatching center provides communication information for the target terminal or the target household node, wherein the communication information is used for establishing communication connection between the target terminal and the target household node; the target terminal obtains the target data from the target home node based on the communication connection. According to the invention, the service cost of the CDN cluster can be reduced, and the CDN service quality can be improved.

Description

technical field [0001] The invention relates to the technical field of CDN, in particular to a data transmission method and a data transmission system. Background technique [0002] By deploying edge nodes in different regions, the CDN cluster enables user terminals in each region to obtain the required business data from the cache server of the edge node nearby, so as to improve the response speed of business services. Specifically, when a user terminal wants to acquire certain service data, the data acquisition request can be directed to the nearest edge node, so that the edge node can establish a connection with the user terminal and provide the locally stored service data to the user terminal . [0003] In the above business data acquisition process, the deployment density of edge nodes has a great impact on the efficiency of data acquisition. The closer the edge node is to the user, the faster the user can obtain the business data, and the more stable the data transmis...
