摘要
具有控制平面与数据平面分离架构的OpenFlow网络为网络创新提供了真实的试验平台。对OpenFlow交换机的工作过程进行了分析,并对OpenFlow软交换机的性能进行了测量分析。测量结果表明,无论对传输控制协议(transfer control protocol,TCP)流还是用户数据包协议(user datagram protocol,UDP)流,OpenFlow软交换机都具有良好的性能,能够满足搭建中小型试验网络的要求;如果有大量的短分组,其吞吐量会明显下降;同时,为高速率UDP流建立表项的过程,也会降低系统效率。
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.
