Virtual Environment Testbed For DSDN Network

Software-defined network (SDN), a centralized network control architecture, Distributed SDN (DSDN)operating systems, and applications are being created to meet the demands of fault tolerance and scalability. However, reliably developing such systems and applications without an expensive testbed can be challenging. Full system virtualization or heavyweight containers remain commonplace in SDN development approaches, which adds complexity and costs at the expense of usability. We show how to use GNS3 as a lightweight container virtual testbed on a single computer, making the process much more straightforward and productive. OpenDaylight is a freely available, distributed network operating system that may be used to build a scalable, adaptable open-source development platform for software in software-defined networks.
