Cisco Catalyst QoS is the first book to concentrate exclusively on the application of QoS in the campus environment. This practical guide provides you with insight into the operation of QoS on the most popular and widely deployed LAN devices: the Cisco Catalyst family of switches. Leveraging the authors' extensive expertise at Cisco in the support of Cisco Catalyst switches and QoS deployment, the book presents QoS from the campus LAN perspective. It explains why QoS is essential in this environment in order to achieve a more deterministic behavior for traffic when implementing voice, video, or other delay-sensitive applications. Through architectural overviews, configuration examples, real-world deployment case studies, and summaries of common pitfalls, you will understand how QoS operates, the different components involved in making QoS possible, and how QoS can be implemented on the various Cisco Catalyst platforms to enable truly successful end-to-end QoS applications.
