Evaluation and Comparison of QoE-Based Admission Control Solutions

The exponential growth of video traffic on the Internet calls for the deployment of network management strategies to enhance the quality experienced by the end-users (Quality of Experience - QoE). In this paper, we focus on admission control, in particular we survey two of the main Admission Control (AC) solutions, and we compare their efficiency and QoE-awareness when making admission decisions. We evaluate the solutions' performance by simulation, and compare them to the ideal QoE-based AC. The results show that only one of the investigated solutions can lead to satisfying decisions if it is properly tuned.
