摘要
OpenFlow specification for SDN networks leaves to external entities the control of the queues inside the switches of the network. SDN typically re-routes flows on less congested paths before they experience QoS violation. This letter outlines an original solution to predict the effect of the re-routing operation by focusing on the packet loss metric. Since the approach is based on collected real-time statistics, it can be easily generalized to other QoS metrics and measurement methodologies.
