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.

Abstract
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.File in questo prodotto:
