The Affects of Busy VoIP Network and Non Busy VoIP Network on QoS VoIP Application using OPNET
Teeb H. Hadi
Abstract :
<p>VoIP is an advanced technology that has a great potential to develop new telecommunication with much lower cost and better QoS. The objective of this research is to study the effect of busy VoIP network and a non busy VoIP network on the VoIP Qos. In this work, simulation tool OPNET Modeler version 14.5 is used to analyze VoIP QoS based on measuring the major factors that influence the QoS for VoIP according to international telecommunication union (ITU) standards including: delay, jitter and packet loss. In this research, a comparison was executed and it was found that when the VoIP network becomes busy; overload happens and causes increase in the end to end delay and packet loss. The replacement of DS1 link by the DS3 link eliminates the overload because the DS3 link has much faster data rate than the DS1 link. As a result, in order to improve the voice quality in a busy VoIP network, it is essential to use a high capacity link such as DS3.</p>
