Quality of Service (QoS) is the set of techniques designed to manage network resources and refers to the capability of a network to provide better service to selected network traffic over various technologies. The primary goal of QoS is to provide a priority ranking to the flow of specific network data, making sure that it does not make other flows fail. QoS technologies provide the elemental building blocks used for current and future business applications.

While Quality of Service has become an essential technology, most of the literature available on the topic focuses on IP QoS. Equally important is the application of QoS in the layer 2 and campus LAN environment, which is primarily responsible for delivering traffic to the desktop. Cisco Catalyst QoS: Quality of Service in Campus Networks provides the reader with insight into the operation of QoS on the various Cisco Catalyst platforms. It aims to give readers the information necessary to understand QoS, the different components involved in making QoS possible, and how it can successfully be implemented on the different switching platforms. This book views QoS from the LAN/campus perspective, and it explains why QoS is essential in this environment in order to achieve a more deterministic behavior for traffic when deploying voice, video, or other delay sensitive applications.
