A data transmission method, related server and storage medium

Abstract

The embodiment of the invention relates to the technical field of data transmission, and discloses a data transmission method, a related server and a storage medium. The data transmission method is applied to the edge node server, including: sending the content transmission request of the requesting end to the origin server; obtaining the response message returned by the origin server according to the content transmission request; if it is determined that the response message carries the traffic requested by the content transmission request data, and transmit the traffic data to the requesting end; if it is determined that the response message carries an error code indicating to request the traffic data from the central node server, then send a content transmission request to the central node server. When transmitting data with less traffic, avoid multi-layer back-to-source and improve the response speed of back-to-source.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data transmission method, a related server and a storage medium. Background technique [0002] In recent years, live video broadcasting has developed rapidly, and competition among major live broadcasting platforms has been fierce. Live video broadcasting has been endowed with more entertainment and social attributes, and people enjoy live broadcasting and watching anytime, anywhere. With the development of the live broadcast business, the head effect is more obvious. A large amount of traffic is concentrated on a few large anchors with high-quality content, and more than 80% of the small and medium-sized anchors have a small number of viewers. [0003] However, the inventors have found that there are at least the following problems in the prior art: existing streaming media applications generally use CDN (Content Delivery Network, Content Delivery Network) to transmi...

Problems solved by technology

However, the traditional CDN live broadcast data distribution scheme has the following disadvantages: CDN generally adopts a multi-layer architecture to ensure the smooth flow of the link, and CDN usually has a three-level or more back-to-source architecture. Both large and small anchors need to go through multi-layer CDN back-to-source

For large hosts, multi-layer CDN back-to-source can reduce the back-to-source bandwidth of the origin station and reduce the pressure, while a large number of small and medium-sized hosts basically go back to the source through the central node due to the small number of viewers, and there is no response The role of merging back to the source, on the contrary, increases a part of the internal cost because of the addition of a layer, and also leads to lengthy links, slow response speed, and relatively high risk
