| Abstract | Because network nodes are transparent in media streaming applications, traditional networks cannot utilize the scalability feature of Scalable video coding (SVC). Compared with the traditional network, SDN supports various flows in a more fine-grained and scalable manner via the OpenFlow protocol, making QoS requirements easier and more feasible. In previous studies, a Ternary Content-Addressable Memory (TCAM) space in the switch has not been considered. This paper proposes a scalable QoS-aware multicast scheme for SVC streams, and formulates the scalable QoS-aware multicast routing problem as a nonlinear programming model. Then, we design heuristic algorithms that reduce the TCAM space consumption and construct the multicast tree for SVC layers according to video streaming requests. To alleviate video quality degradation, a dynamic layered multicast routing algorithm is proposed. Our experimental results demonstrate the performance of this method in terms of the packet loss ratio, scalability, the average satisfaction, and system utility. |
