Abstract

In the last few years, the use of Video and Voice Over Internet Protocol (VVOIP) has grown rapidly due to its cost effectiveness and dramatic functionality over the traditional telephone network. Reliance on VVOIP applications like video conferences, video calls and live videos has become imperative recently since following social-distancing guidelines as a result of the widespread of COVID-19 pandemic. In spite of the increase in the internet traffic and the limitation of bandwidth, the customers always need more interactive multimedia applications with high quality and efficiency. Hence, the quality of delivery for VVoIP applications should be measured and optimized to ensure Quality of Service (QoS) and Quality of Experience (QoE) support to customers in real time video call systems. In this paper, video-related QoE metrics like quantization parameter (QP), frame rate (FR) and resolution are implemented for quality evaluation of a video call over live service network based on IP multimedia subsystem (IMS). Furthermore, this paper investigates the effect of bandwidth limitation on network-related QoS parameters such as packet loss and jitter and then on video calls QOE on a live network based on IMS by using a Wireshark 3.0.0 software as protocol analyzer to define QoE and QoS metrics and to determine the best performance of VVoIP systems.
