Queuing Disciplines for VoIP and High Resolution Video Application Services Using OPNET Tool

Abstract: The Internet has now turned into such a significant communications that is able of distribution information within a very short time and easy to access. It is considered as community networks that provide reasonable WAN services to most customers. Applications such as video conferencing and VoIP are the example of typical network applications supported by the Internet Protocol. A variety of queuing disciplines be able to be used to manage packet transmission based on the accessible bandwidth. When congestion occurs, some of the packets will be dropped (buffer space) accordingly. The queuing technique requires to be used in every router to control the transmission of packets. This paper presents a comparative study and the effect of different type of queuing techniques such as FIFO (first in first out), PQ (Priority Queuing), and WFQ (Weight Fair Queuing) on network application such as high Resolution video conference, VoIP(Voice over IP).
