FTTR dynamic bandwidth allocation method based on traffic space-time characteristic prediction

The invention discloses an FTTR dynamic bandwidth allocation method based on traffic space-time characteristic prediction, and the method comprises the steps: building and configuring a data collection environment, and recording the log information of an ONU-AP; log information is extracted, and the flow data is corrected; carrying out dimensionality reduction on the characteristic value of the traffic data to obtain total traffic information of each ONU-AP, and predicting the traffic of each ONU-AP in the next polling period by using traffic time characteristics; predicting the moving track of the user in the next period by using spatial characteristics; and reporting the bandwidth request predicted by the next polling after the polling is finished, and obtaining the bandwidth authorized by the OLT to send the user data. The invention provides an FTTR dynamic bandwidth allocation method based on traffic space-time characteristic prediction, so that an OLT pre-allocates bandwidth information of next polling,
