Performance Comparison of Voice Packet Sizes in the FIFO Adversarial Queuing and FIFO M/M/1 Model

First-In-First-Out (FIFO) is the most widely used scheduling protocol in packet switching network. In fact, it is one of the simplest queuing policies used to provide best effort services in packet-switched network. However, the performance of FIFO is really crucial when it related to stability i.e. question of whether there is a bound on the total size of packets in the network at all times. In this study, the primary objective is to find the optimum packet size of voice packet when using FIFO adversarial network and FIFO M/M/1 network. The new approach is based on adversarial generation of packets so that positive results are more robust in that they do not depend on particular probabilistic assumptions about the input sequences.
