Predictive network management for real-time video with varying video and network conditions

A system for managing video delivery from a plurality of video cameras, the system comprising:

• a plurality of edge devices, which are coupled to the video cameras and to respective modems that transmit the video stream generated by the video cameras in a sequence of frames over a shared communication channel;
• and
• a processor, configured to:
• obtain, at least from the edge devices, data values of parameters indicative of (i) video rates of video streams generated by the video cameras, (ii) transmission rates used by the modems for transmitting the video streams in the sequence of frames over the shared communication channel, and (iii) a channel communications bandwidth supportable by the sequence of frames transmitted over the shared communication channel for the video streams;
• calculate predicted values of the video rates, the transmission rates and the channel communications bandwidth;
• and
• based on the predicted values, (i) detect that at a given future time, a time duration required for transmitting the video streams using a current configuration of the edge devices will exceed a supportable time duration of the sequence of frames, and (ii) define an updated configuration of the edge devices that will comply with the supportable time duration of the sequence of frames at the given future time;
• instruct the edge devices in advance, at a time that precedes the given future time, to re-configure generation or transmission of the video streams from the current configuration to the updated configuration;
• and
• subsequently receive from the edge devices video streams in accordance with the updated configuration, which comply with the supportable time duration of the sequence of frames at the given future time and therefore comply with the channel communications bandwidth supportable by the shared communication channel.
