Measuring performance of the OpenFlow software switch
OpenFlow软交换机的性能测量

The OpenFlow network, which separates the control plane from the data plane, provides a real platform for innovation in the Internet. The working processes of the OpenFlow switch are analyzed, and the performance of the PC-based OpenFlow switch is measured and analyzed too. The experimental results depict that no matter for the TCP or the UDP packet transmitting, the PC-based OpenFlow switch can have a good performance in the moderate scale OpenFlow network. However, the throughput will decline rapidly when lots of short packets arrive at the switch. And the flow entries constructing for the high-speed UDP packets will depress the performance of the OpenFlow network too.
