PIM-compliant SDN-enabled IP multicast service

Software-defined networking (SDN) has been a promising solution to multicast streaming data due to its scalability and manageability. However, offering a multicast service that spans a large geographical area is still challenging because we still lack a unified multicast scheme that interconnects independent SDN-managed networks and bridges the service between SDN- based networks and the rest of the Internet. This paper proposes a solution that integrates SDN, CORD, and PIM technologies. We provides preliminary performance evaluation results. This work serves as a stepping stone to the ultimate goal of multicast as a service.
