Abstract

Differentiated services (Diffserv) is a new service model proposed by the Internet Engineering Task Force (IETF) to provide an end-to-end quality of service (QoS) support for multimedia applications. One key element of Diffserv is the definition of different per hop behaviors (PHB) like Expedited Forwarding (EF) and Assured Forwarding (AF). EF can be used to build a low loss and low delay service to support Internet telephony and video conferencing. In this paper we study the performance of Voice over Internet Protocol (VoIP) over Diffserv using EF. We compare the delay and jitter performance of the traffic generated by different standard voice codec algorithms used for compressing a voice signal
