Abstract
As so›ware-deÿned networking (SDN) grows beyond its original aim to simply separate the control and data network planes, it be-comes useful both ÿnancially and analytically to provide adequate mechanisms for simulating this new paradigm. A number of simu-lation/emulation tools for modeling SDN, such as Mininet and ns-3, are already available. However, none of them supports multiple auxiliary connections in SDN simulation/emulation, which is one of the key features added in OpenFlow 1.3. In this paper, we ex-tended the existing OFSWITCH13 framework to support multiple auxiliary connections in SDN simulations based on ns-3. „is work allows multiple TCP/UDP connections to be built between a switch and a controller in the simulation. Furthermore, we performed case studies to investigate the impact of auxiliary connections on SDN performance, which is valuable for designing a scalable SDN network.
