| Abstract | In this report, we compare the forwarding latency of an OpenFlow hardware switch and software switch, namely, the hardware switch NEC PF5240 and the software switch Open vSwitch. We consider different parameters influencing the forwarding latency such as the definition of match tuples (combination of header fields to be matched), different packet sizes, or varying sizes of flow tables. Our evaluations show that hardware switches reduce the forwarding latency by up to 97% and also reduce the variance of latency significantly.
