End-to-end QoS deployment techniques for Cisco Catalyst series switches
Examine various QoS components, including congestion management,congestion avoidance, shaping, policing/admission control, signaling,link efficiency mechanisms, and classification and marking
Map specified class of service (CoS) values to various queues andmaintain CoS values through the use of 802.1q tagging on the CiscoCatalyst 2900XL, 3500XL and Catalyst 4000 and 2948G/2980G CatOS Familyof Switches
Learn about classification and rewrite capabilities and queue scheduling on the Cisco Catalyst 5000
Implement ACLs, ACPs, ACEs, and low-latency queuing on the Cisco Catalyst 2950 and 3550 Family of Switches
Understand classification, policying, and scheduling capabilities of the Catalyst 4000 and 4500 IOS Family of Switches
Configure QoS in both Hybrid and Native mode on the Catalyst 6500 Family of Switches
Utilize Layer 3 QoS to classify varying levels of service with the Catalyst 6500 MSFC and Flexwan
Understand how to apply QoS in campus network designs by examining end-to-end case studies
Quality of service (QoS) is the set of techniques designed to managenetwork resources. QoS refers to the capability of a network to providebetter service to selected network traffic over various LAN and WANtechnologies. The primary goal of QoS is to provide flow priority,including dedicated bandwidth, controlled jitter and latency (requiredby some interactive and delay-sensitive traffic), and improved losscharacteristics.
While QoS has become an essential technology for those organizationsrolling out a new generation of network applications such as real-timevoice communications and high-quality video delivery, most of theliterature available on this foundation technology for current andfuture business applications focuses on IP QoS. Equally important isthe application of QoS in the campus LAN environment, which isprimarily responsible for delivering traffic to the desktop.
Cisco Catalyst QoS is the first book to concentrate exclusively onthe application of QoS in the campus environment. This practical guideprovides you with insight into the operation of QoS on the most popularand widely deployed LAN devices: the Cisco Catalyst family of switches.Leveraging the authors’ extensive expertise at Cisco in the support ofCisco Catalyst switches and QoS deployment, the book presents QoS fromthe campus LAN perspective. It explains why QoS is essential in thisenvironment in order to achieve a more deterministic behavior fortraffic when implementing voice, video, or other delay-sensitiveapplications. Through architectural overviews, configuration examples,real-world deployment case studies, and summaries of common pitfalls,you will understand how QoS operates, the different components involvedin making QoS possible, and how QoS can be implemented on the variousCisco Catalyst platforms to enable truly successful end-to-end QoSapplications.
This book is part of the Networking Technology Series from CiscoPress, which offers networking professionals valuable information forconstructing efficient networks, understanding new technologies, andbuilding successful careers.
