    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。

    Abstract:

    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.
