Cisco Catalyst QoS: Quality of Service in Campus Networks

Product Description

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 and maintain CoS values through the use of 802.1q tagging on the Cisco Catalyst 2900XL, 3500XL and Catalyst 4000 and 2948G/2980G CatOS Family of 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 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 delay-sensitive 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. 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.

This book is part of the Networking Technology Series from Cisco Press, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

6 of 6 people found the following review helpful Dry, but Useful..., February 17, 2004 By  Rich Hill (Kansas City, MO) - See all my reviews    This review is from: Cisco Catalyst(R) QoS: Quality of Service in Campus Networks (Hardcover) Vital Statistics: I am reviewing Cisco Catalyst QOS: Quality of Service in Campus Networks (ISBN: 1-58705-120-6). The book is 400 pages in length and is divided into 2 sections, Fundamental QOS Concepts and Advanced QOS Concepts. It includes coverage of QOS functionality on 2900, 3500, 4000 & 6500 series Cisco Catalyst Switches. The book states that it is intended for network engineers who work with Catalysts and seek a deeper understanding of QOS. Add CCNP level switch understanding to that list, at the very least. The book's authors are Mike Flannagan, Richard Froom, and Kevin Turek, all CCIE-level engineers who work directly for Cisco in Research Triangle Park. Notice the presence of "authors", "engineers" and "research" in one sentence... a fearful combination to say the least. Buckle up, kids, it's gonna be a bumpy ride. My Reading Experience: I set out to read this book as an attempt to get an understanding of QOS for my CCIE studies. Oops, Rich didn't...

Connelly "Just a bithead - CCIE#17085" (Alexandria, VA) - See all my reviews    This review is from: Cisco Catalyst(R) QoS: Quality of Service in Campus Networks (Hardcover) "Cisco Catalyst QoS" by Flannagan, Froom, and Turek is one of a few books by Cisco dedicated to one platform and one feature of that platform. As a long-time CCIE candidate, I have found this book very useful in complementing my studies of the Catalyst 3500. But this book does much more than simply discuss the 3500. In particular, items I found important: * The book starts out by giving an in-depth review of how QoS is applied to the Catalysts. For example, the excellent diagram on page 13 shows how different entities may all employ QoS services (CAC, FRTS, cRTP, etc..) * Next, the book moves through the different QoS components - from scheduling, to token bucket mechanisms, traffic-shaping and policing. * The beauty of the book is shown around page 150 - the CoS to DSCP map. This is a sparsely documented area of QoS, and the only reference outside of Cisco (that I've found) which succinctly explains the layer 2 to layer 3 mappings for Catalyst IOS...

This is some of the best QoS reference material around, and it' s less then 400 pages. You can't beat the value this book offers. Being a CCIE candidate and having attempted the lab once I have read quite a few books and articles on Quality of Service. I enjoyed every page of this book for the detail and wealth of information it contained within its chapters. The first chapter of this book is dedicated to providing the foundation for the various types QoS. You are given easy to understand explanations on (DiffServ, Integrated Services, WFQ. PQ, CQ, WRED,etc) It's by far the best information I have ever read. The authors do an incredible job in explaining this to the reader. You are given reasons for implementing QoS in your network. They discuss bandwidth, jitter, types of delays, and packet loss in laymen terms. Once you have a good grasp...
