Problems solved by technology

[0004] During the live broadcast, the user's viewing quality may be affected due to jitter (for example, the live broadcast picture freezes), so it is hoped to accurately detect whether jitter occurs in the CDN to reduce the negative impact of jitter

Abstract

The present disclosure provides a method, apparatus, device and medium for detecting live broadcast jitter, which relate to the field of computer network technologies, and in particular, to the field of cloud services. The implementation scheme is: for the live stream transmitted by the edge CDN node in the CDN of the content distribution network, the quality information of the live stream is calculated based on the transmission frame rate and the number of viewings of the live stream; based on the quality information of the live stream, the quality information; and, based on the quality information of the edge CDN node, judging whether jitter occurs at the edge CDN node.

Description

technical field [0001] The present disclosure relates to the field of computer network technologies, in particular to the field of cloud services, and in particular to a method, apparatus, electronic device, computer-readable storage medium, and computer program product for detecting live broadcast jitter. Background technique [0002] Content Delivery Network (CDN for short) is an intelligent virtual network built on the basis of the existing network. It relies on edge servers deployed in various places, through the load balancing, content distribution, scheduling and other functional modules of the central platform, so that the Users can obtain the desired content nearby, reduce network congestion, and improve user access response speed and hit rate. [0003] In order to meet the needs of a large number of users to watch live streams, it is often necessary to use CDNs to distribute live streams. The CDN architecture currently used for live broadcasting is a multi-level ar...
