SDN-based adaptive cloud network management for 3D rendering and streaming services In this work, we present a SDN-based adaptive cloud network management for 3D rendering and streaming services. In the proposed system, SDN is adopted to provide flexible and intelligent control of cloud network resources. By considering server load and network link states simultaneously, 3D graphic rendering servers, encoding servers, and data transmission paths are dynamically determined with low computational complexity. The proposed system is implemented using the OpenDaylight SDN controller and Mininet network emulator. Finally, simulation results are provided to demonstrate the performance of the proposed system.
