Quality of Service (QoS) is an essential element to building a flexible, accessible, and efficient network. Its role in multiple technologies underlines the need for most networking professionals to master the features that implement QoS. QoS, and specifically the QoS features that an IT professional implements on different technologies, helps prioritize and guide traffic flows in a manner that maximizes the client experience. This prioritization is just one element of QoS, and numerous features can be used to determine this flow. As more complex technologies like Voice over IP are implemented on networks, QoS will become more vital. This is especially true when these technologies increase the number of those accessing and using the network. W. Odom, M. J. Cavanaugh ISBN 1-58720-058-9
