DATA TRANSMISSION METHOD, RELATED APPARATUS, DEVICE AND STORAGE MEDIUM

The present application discloses a data transmission method for a content delivery network, and a related apparatus, a device and a storage medium, and can be applied to fields including but not limited to live broadcast, Internet of Vehicles, instant messaging, etc. The method of the present application comprises: receiving a first data frame sequence sent by a source device in a first time window; according to the first data frame sequence, determining data jitter information, the data jitter information being used to describe data frame jitter within the time window; according to the data jitter information, setting a first buffer duration threshold for a data buffer; and if the playback duration corresponding to data frames currently contained in the data buffer is greater than or equal to the first buffer duration threshold, then increasing the transmission rate of the data buffer data frames to a target device. The present application effectively avoids large delays in content streams and better-satisf
