Abstract :
Video constitutes a large fraction of Internet traffic today. The growth of mobile video has been significant in recent years, due to a tremendous increase in mobile device adoption and the ease with which videos are generated and consumed by such devices. Although the demand for mobile videos is significantly on the rise, the network infrastructure resources needed to deliver mobile videos haven´t increased proportionally. This article discusses challenges in delivering streaming videos over cellular networks and possible ways to tackle those problems. Also considered is the potential impact of virtualizing network functions and services on mobile video delivery.
