ABSTRACT: The paper presents the simulation results
of the comparison of three Queuing Mechanisms, First in First out (FIFO),
Priority Queuing (PQ), and Weighted Fair Queuing (WFQ). Depending on their
effects on the network’s Routers, the load of any algorithm of them over
Router’s CPUs and memory usage, the delay occurred between routers when any
algorithm has been used and the network application throughput. This comparison
explains that, PQ doesn’t need high specification hardware (memory and CPU) but
when used it is not fair, because it serves one application and ignore the
other application and FIFO mechanism has smaller queuing delay, otherwise PQ
has bigger delay.
