Quality assessment of VoIP services: A proposal based on the measurement of the IP Packet Delay Variation

Abstract

Generally, the voice quality of a VoIP call can be analyzed through the measurement of suitable metrics at the application layer of the International Organization for Standardization/Open Systems Interconnection (ISO/OSI) protocol stack. However, the peculiarities of such a kind of measurements make very difficult to provide to each user a value representative of the quality of each VoIP call.
