Short descripton:
 
Media streaming services, such as IPTV, Video-On-Demand (VOD), and video calling, continue to emerge requiring more and more network resources.For example, several studies predict that mobile video data traffic would increase 15-20 times by 2018. This demand increase affects the quality of service of video streaming sessions resulting in problems such as interrupted streaming, large session setup delay, and reduced video quality. Many of the existing solutions solely depend on end-to-end quality improvement approaches. Recently, Software-Defined Networks (SDNs) promise a high degree of flexibility in network control, providing an impetus to consider network-oriented solutions for improving video streaming performance. Our research aim is the design of suitable network control enhancements, to analyse their operational behaviour, and to evaluate their impact on user quality of experience and network resource utilisation.  Our  hypothesis  is that solving these problems requires a coordinated network system capable of controlling and optimising video delivery to end-users. Solutions that are exclusively client-side or server-side struggle to infer a sufficiently accurate view of the network resource. Our approach exposes the network state, allowing a managed response to video delivery.
