Preface
Quality of Service, or QOS, is in the spotlight for many different router vendors. Its prominence is visible by the presence of new QOS features and enhancements in each launch of new software and hardware. However, because standards bodies do not define QOS, the implementation and configuration of QOS varies among the different router brands, and can change as the software and hardware are updated.
This book focuses on the aspects of QOS that do not change: the roots and foundations of the QOS realm. Knowledge of the foundations of QOS is the key to understanding what benefits it offers and what can be built on top of it. This knowledge will help the reader engage in both the conceptual and actual tasks of designing or implementing QOS systems, thinking in terms of the concepts, rather than thinking of QOS simply as a series of commands that should be pasted into the router configuration. It will also help the reader to troubleshoot a QOS network, to decide whether the undesired results being seen are a result of misconfigured tools that require some fine-tuning or the wrong tools. As Galileo Galilei once said, “Doubt is the father of all invention.”
Although both authors work for the same router vendor, this book is completely vendor agnostic, and we have shied away from showing any CLI output or discussing hardware-specific implementations.
