Abstract :
QoS is a measure of the level of service provided to users and is the degree of confidence that an application can have in meeting the needs of the network. Various factors are involved in evaluating the quality of service, including availability, efficiency, the time required to communicate, percentage of successful transfers, and speed of error detection and correction. In the VoIP category, service quality is measured in terms of available and available bandwidth, packet loss rates, latency, and jitter changes. In order to have the desired quality in high-delay applications on the IP network, it must be ensured that the values of the mentioned parameters for each session are in a certain range. In this paper, the presented solutions in the field of digital signal processing to improve the quality of service are expressed and in each step, the results of the simulations are compared and evaluated. Finally, an attempt has been made to select and determine the optimal method.
