The wide-scale deployment of Intranet and Internet along with improvements in hardware and software technologies are paving the way for emerging applications, many of which involve the delivery of voice, video and images to end-users. One such application that has generated considerable interest recently is voice over IP (VoIP). The impact and feasibility of using VoIP in both Intranet and Internet environments is explored under typical network real-world measurement conditions. The empirical test measurements and results demonstrate the effects of compression, packet size, delays and jitter on the end-to-end delivery performance of voice ultimately delivered to end-users. An analysis is presented of the delay components of the end-to-end delay for VoIP implementation. This analysis identifies areas that could potentially influence the performance of voice when transported over IP-based networks and simultaneously competing with their data traffic.
