SDN-based mobile packet core for multicast and broadcast services
- 215 Downloads
The current mobile packet core network is evolving to cope with the pressure of the mobile traffic explosion and the advent of new services. Software-defined networking (SDN) is currently being adopted as one of the promising drivers for redesigning the mobile packet core network toward a 5G network. SDN-based mobile packet core approaches are expected to deliver features, such as fast service deployment, flexibility, and capital expenditure and operational expenditure reduction within future 5G networks. However, current SDN-based mobile packet core approaches only focus on providing unicast services without considering multicast and broadcast services. In this article, we propose an efficient SDN-based mobile packet core network architecture for supporting multicast and broadcast services. The proposed architecture takes advantage of the SDN paradigm and enables multicast and broadcast service deployment. In addition, a new SDN-based multicast subscription procedure is introduced to reduce network bandwidth resources. By numerical analysis, our scheme improves the current multicast and broadcast solution in terms of signaling cost.
