Center node: "bigdatasdnsim a simulator for analyzing big data applications in software defined cloud data centers"
  Abstract: Emerging paradigms of big data and Software-Defined Networking (SDN) in cloud data centers have gained significant attention from industry and academia. The integration and coordination of big data and SDN are required to improve the application and network performance of big data applications. While empirical evaluation and analysis of big data and SDN can be one way of observing proposed solutions, it is often impractical or difficult to apply for several reasons, such as expensive undertakings, time consuming, and complexity; in addition, it is beyond the reach of most individuals. Thus, simulation tools are preferable options for performing costeffective, scalable experimentation in a controllable, repeatable, and configurable manner. To fill this gap, we present a new, self-contained simulation tool named BigDataSDNSim that enables the modeling and simulating of big data management systems (YARN), big data programming models (MapReduce), and SDN-enabled networks within cloud computing environments. To demonstrate the efficacy, effectiveness, and features of BigDataSDNSim, a use-case that compares SDN-enabled networks with legacy networks in terms of the performance and energy consumption is presented.
