摘要
The disclosure relates to technology for a 360 degree video stream in a network. A network round trip time (RTT) is measured for a requested FoV of the 360 degree video stream, where the RTT indicates a time interval between sending a FoV interest message and receiving a response message in reply to the requested FoV. The network bandwidth is measured for the requested FoV of the 360 degree video stream, where the measured network bandwidth represents an amount of data the network transmits in the response message. A future FoV of the 360 degree video stream is then determined based on the requested FoV, the measured network bandwidth and the measured network RTT, and a video stream is prefecthced for the future FoV of the 360 degree video stream.
