Embodiments of the present application provide a bandwidth
authorization method, device and
system, storage medium and electronic device, wherein the method comprises: obtaining data sending information of multiple data sent by an
optical network unit (ONU); determining target data from the multiple data based on
time information of each data; analyzing the target data to determine a data packet length, a target sending time and a target sending period of the target data; sending a target bandwidth time matching the data packet length, the target sending time and the target sending period to the ONU to instruct the ONU to send subsequent target data according to the target bandwidth time. Through the present application, the problem of
system bandwidth waste caused by eliminating the time
delay and
jitter of data sending in the related art is solved.
