Data buffering method, network device, and storage medium

A network device, comprising:

• circuitry configured to:
• obtain multimedia data and network characteristic information of a network connection, the network connection including a first network connection or a second network connection, the first network connection being configured to transmit the multimedia data from a host device or a source site to the network device, and the second network connection being configured to transmit the multimedia data from the network device to a terminal device;
• determine, at least based on the network characteristic information of the network connection, a target data volume corresponding to the terminal device;
• determine, based on the obtained multimedia data, first buffered data representing the multimedia data, the first buffered data having the target data volume;
• send the first buffered data to the terminal device by using the second network connection, a data volume of the first buffered data matching the network characteristic information;
• before the terminal device establishes the second network connection with the network device:
• obtain a broadcast parameter of the terminal device, the broadcast parameter indicating broadcast performance of playing the multimedia data by the terminal device,
• determine, based on the broadcast parameter, a preset data value corresponding to the terminal device, and
• determine second buffered data of the multimedia data based on the obtained multimedia data, a data value of the second buffered data being the preset data value;
• and
• after the terminal device establishes the second network connection with the network device, receive a target instruction from the terminal device requesting the second buffered data.

A non-transitory computer-readable medium storing a program executable by a processor to perform a data buffering method, the method comprising:

• obtaining multimedia data and network characteristic information of a network connection, the network connection including a first network connection or a second network connection, the first network connection being configured to transmit the multimedia data from a host device or a source site to a network device, and the second network connection being configured to transmit the multimedia data from the network device to a terminal device;
• determining, at least based on the network characteristic information of the network connection, a target data volume corresponding to the terminal device;
• determining, based on the obtained multimedia data, first buffered data representing the multimedia data, the first buffered data having the target data volume;
• sending the first buffered data to the terminal device by using the second network connection, a data volume of the first buffered data matching the network characteristic information;
• before the terminal device establishes the second network connection with the network device:
• obtaining a broadcast parameter of the terminal device, the broadcast parameter indicating broadcast performance of playing the multimedia data by the terminal device,
• determining, at least based on the broadcast parameter, a preset data value corresponding to the terminal device, and
• determining second buffered data of the multimedia data based on the obtained multimedia data, a data value of the second buffered data being the preset data value;
• and
• after the terminal device establishes the second network connection with the network device, receiving a target instruction from the terminal device requesting the second buffered data.
