Analysis of QoS and QoE Metrics of IPTV Multicast Video Traffic on a LAN TestBed

Abstract

Analog television systems have been around for over 70 years now. Over this period, viewers have witnessed several improvements, including the transition from black and white to color television. In the last few years, the industry has undergone a profound transition, migrating from conventional television to a new digital era. Indeed, digital television has become the most significant advance in television technology, providing users with multiple options, increased flexibility and an enhanced interactive visual experience. Internet Protocol television (IPTV) constitutes a means to carry a stream of video content over a network using an Internet protocol (IP). The ultimate goal of IPTV is offering a completely personalized experience, ensuring Quality of Service (QoS) and QoE (Quality of Experience) within the organization, including LAN networks of a television channel or traditional LAN networks. This research study analyzes the behavior of IPTV traffic in an experimental LAN with controlled traffic, and is the continuation of a previous experimental study discussed in a paper presented at CACIC 2022. Different codecs are used for comparison purposes, using detailed quantitative results of QoS metrics as well as a basis to establish indicative QoE values. The findings reported in this paper offer guidance on suitable software and network topology configurations for managing similar networks, in addition to providing detailed values for simulation analysts.
