Video streaming multicast is an urgently needed application, but is hard to implement in traditional networks as it requires support of multicast routing and QoS guarantee. Software-Defined Networking is an innovative network architecture that abstracts network control and global network view to a logically centralized controller, therefore makes the introduction of new network services and protocols simplified. In this paper, we realize a video streaming multicast application on SDN networks, which can efficiently deliver hierarchically coded video streaming to multiple recipients with as good quality of service as the network and terminals allow. We describe the framework and implementation details of the application, and verify it on an emulation platform.
