Comparative of different queuing technique in high resolution video conference, FTP and VoIP

The Internet has now become such an important infrastructure that is capable of sending information within a very short time and easy to access. It is considered as public networks that provide affordable WAN services to most customers. Applications such as video conferencing, file transfer protocol and VoIP are the example of typical network applications supported by the Internet Protocol. Various queuing disciplines can be used to control packet transmission based on the available bandwidth. When congestion occurs, some of the packets will be dropped (buffer space) accordingly. The queuing technique need to be used in each 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, FTP (File Transfer Protocol) and VoIP (Voice over IP).
