Abstract:
To overcome the current limitations of the Internet, several
different approaches are existing which can be mainly distinguished into network-aware applications and application-aware networks. Bringing together both approaches, network-application interfaces are to be deployed to realize smart applications as well as smart mediation of application data through the Internet. Via this interface,
the application and the mediation network can directly communicate with each other and exchange information adequately, such that the end user experiences a good quality. While smart mediation includes resource management as well as traffic management to optimally utilize network resources and to deliver the contents according to the application requirements, smart applications react dynamically on the current network situation for optimal QoE, e.g., by reducing application requirements. In this work, we consider live streaming services based on connectionless transport protocols like video conferencing and IPTV with high video quality playback demands.
The main goal of this work is to optimize the Quality of
Experience (QoE) for live video streaming by real-time adaptation of the required video bitrate and thus the video quality to the current network situation (i.e., available bandwidth or unreliable links with packet losses).
