Embodiment Construction
[0070] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0071] A SDN traffic prediction algorithm based on RBF neural network, the specific steps are as follows:
[0072] Step 1: SDN traffic measurement and sampling
[0073] The specific process of the equal time interval sampling algorithm is as follows:
[0074] First select the network flow to be measured, and then determine the network path through which the measured network flow passes, thereby determining the switch through which the network flow passes. Set the sampling period, the controller periodically sends FlowStatisticsRequest messages to the switch, the switch receives the FlowStatisticsRequest message, sends a FlowStatisticsReply message to the controller, and then divides the obtained bytes by the sampling interval to obtain the average information transmission rate within the time interval. These statistics are stored for simulatio...
