Abstract:
The article presents some investigations about performance for transporting compressed voice over packet-based networks. The scope is to determine optimal values for major parameters of the voice networks (packet size and dejittering delay) to meet the requirements of providing an acceptable Quality of Service (QoS). It is demonstrated by analyzing the behavior of two identical compressed voice networks that it is possible for voice over packet (IP or ATM) to meet QoS requirements if the networks are properly managed and provided with optimal parameters. The analysis is performed for Voice over IP networks with reference to Voice over ATM networks.
