Introduction
The objective of this project is to examine the Effects of different router queuing policies on different types of data traffic using OPNET.
This covers the presentation of the affects of different queuing disciplines on packet delivery for three applications: File Transfer Protocol, Video and Voice over IP. For modeling, simulation and analyzing on these applications is used OPNET [Optimized Network Engineering Tool] environment. In this work it is investigated how the choice of the queuing discipline can affect the applications and utilization of the network resources in the routers.
Background
Being part of the supply portion methods, each router
