Efficient multicast algorithms for scalable video coding in software-defined networking

Software-Defined Networking (SDN) is a new approach to design, build and manage computer networks. Multicast is used to transmit the same video file to different users. In this paper, we propose two multicast algorithms to solve the multicast problem in SDN environment. Both algorithms consider the balance of bandwidth utilization and communication delay between the source and clients. Simulation results show that our algorithms can improve the network bandwidth utilization and successful rate of the multicast requests than the previous works.
