Behavior of Voice Codecs QoS Metrics in the IP Network Overload Zone
Vladimir Vichev, Todorka Georgieva · 2024
Audio communications in IP-based networks have undergone a transformative shift with the advent of VoIP applications. The remarkable cost-efficiency of VoIP has cemented its role as the dominant communication method in the modern world, a trajectory that shows no signs of waning. VoIP performance is critically dependent on the efficiency of the audio codecs utilized in any given communication scenario, underscoring the importance of examining audio codec QoS parameters in IP networks. This paper delves into the performance analysis of several widely-used audio codecs, how each of the codecs QoS parameters reacts in the network congestion zone. How wide is this zone for each of them and how stable are its parameters before entering it.
