Video delivery over next generation cellular networks

The rapidly increasing use of mobile devices, such as smart phones and tablets, as well as the high popularity of mobile applications and especially video streaming incur an increasing traffic demand on mobile cellular systems. The cloud computing and the software defined networking (SDN) paradigms constitute suitable tools for mobile networks to efficiently handle the increasing video traffic. In this paper, we focus on content and, in particular, video delivery services on top of emerging and next generation cellular networks which employ SDN in their core, mainly from a business standpoint. We analyze the stakeholders and their business interests and relationships, also providing a value network and business model analysis for both existing and emerging use cases of interest.
