SDN部署依赖于来自不同供应商的交换机，这些交换机在性能和可用功能方面有所不同。了解这些差异和性能特征对于确保成功部署至关重要。在本文中，我们测量、报告和解释了三种硬件OpenFlow交换机中流表更新的性能特征。我们的研究结果可以帮助控制器开发人员，使他们的程序效率。此外，我们还强调了OpenFlow规范及其实现之间的差异，如果忽略这些差异，将对网络安全性和正确性构成严重威胁。
SDN deployments rely on switches that come from various vendors and differ in terms of performance and available features. Understanding these differences and performance characteristics is essential for ensuring successful deployments. In this paper we measure, report, and explain the performance characteristics of flow table updates in three hardware OpenFlow switches. Our results can help controller developers to make their programs efficient. Further, we also highlight differences between the OpenFlow specification and its implementations, that if ignored, pose a serious threat to network security and correctness.
