Best Paper Award for new QoE-fair Video Streaming Adaptation Logic goes to AIT Scientists

Michael Seufert, Scientist at Center for Digital Safety & Security, AIT

At the 14th International Conference on Network and Service Management (CNSM 2018) in Rome, Michael Seufert and Pedro Casas, Scientists at the AIT Center for Digital Safety & Security, and Nikolas Wehner, Junior Research Engineer at the AIT Center for Technology Experience were awarded with the Best Paper Award for their paper entitled: "A Fair Share for All: Novel Adaptation Logic for QoE Fairness of HTTP Adaptive Video Streaming"

This paper presents a novel adaptation logic for HTTP adaptive streaming (HAS), which achieves not only a high Quality of Experience (QoE) but also high QoE fairness among independent and heterogeneous clients. The algorithm forces video clients to adapt the requested quality level based on the current network conditions and their individual bit rate requirements, such that the overall quality levels selected by all currently active streaming clients are fairly distributed, i.e., they do not diverge too much. The design of the algorithm is inspired by the well-known Transmission Control Protocol (TCP) congestion control, and drives heterogeneous clients to independently converge on similar quality levels without the need for communicating with each other and/or with a centralized controller in the network. By defining quality levels with equal visual quality, and preparing video representations accordingly, the quality level fairness is extended to QoE fairness.

Congratulations!

About CNSM
The International Conference on Network and Service Management (CNSM) is a single-track conference that evolved from MANWEEK ("Management Week") workshops such as DSOM, MMSN, IPOM. The goal of CNSM is to establish itself as the main forum of research where advancements in the state-of-the-art on network and service management can be discussed and debated.
