Simulation of OpenFlow scenarios based on NSDL and NS-3

The management of OpenFlow experiments can be a complex task considering the number and the degree of configuration of the resources involved. This task would be straightforward if the existing heterogeneous tools could be applied together in order to optimize the management of these networks. The work presented in this paper applies the NSDL Framework in order to provide a common environment for enabling interoperability among OpenFlow compliant tools. In particular, we take advantage of the interoperability provided by NSDL for the utilization of different network tools and libraries aiming to create and analyze Software Defined Networks focusing on OpenFlow scenarios. Therefore, this paper addresses the utilization of a graphical user interface, called Visual Network Description, for the authoring of OpenFlow scenarios, the simulation of these scenarios using NS-3, and the application of the NSDL Framework for the integration of these tools. In particular, the integration provided by NSDL will enable the utilization of independent tools as complementary tools, allowing a more complete management and analysis, and contributing to enrich the best practices in OpenFlow networks authoring and management.
