manage network resources QoS refers to the capability of a network to provide better service to selected network traffic over various LAN and WAN technologies The primary goal of QoS is to provide flow priority, including dedicated bandwidth, controlled jitter and latency (required by some interactive and delaysensitive traffic), and improved loss characteristics While QoS has become an essential technology for those organizations rolling out a new generation of network applications such as real-time voice communications and high-quality video delivery, most of the literature available on this foundation technology for current and future business applications focuses on IP QoS Equally important is the application of QoS in the campus LAN environment, which is primarily responsible for delivering traffic to the desktop 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 • Table of Contents Leveraging the authors' extensive expertise at
