DESCRIPTION:
Curtis Murphy, CCIE #1521, is an engineer in Cisco's Serviceability Design Department in Research Triangle Park, specializing in IOS software products. He has worked in the networking industry since 1989 and at Cisco since 1994. While at Cisco, he has worked both as an IBM protocols specialist in the Technical
By understanding the internal operations of IOS Software, you will be able to take architectural considerations into account when designing networks and isolate problems more easily when troubleshooting networks. Finally, an overview of IOS Quality of Service (QoS) is provided, including descriptions of several QoS methods, such as priority queuing, custom queuing, weighted fair queuing, and modified deficit round robin. Beyond understanding the Cisco IOS command set, comprehending what happens inside Cisco routers will help you as a network designer or engineer to perform your job more effectively. IOS Software provides the means by which networking profession
Deepens your understanding I bought this book and read it cover to cover in about two weeks (which for me is pretty good). It's definitely not for beginners, in fact it really benefits people who are running BFRs like 7200 and bigger. Good detail about 7500 and 12000 architectures.It also gave me a lot of little bits of knowledge that made sense but I hadn't thought about before. Example - if you have a 7206 stacked with fast ethernet cards but your only using half of them, IOS is allocating buffer space to every inte. A Customer said A brilliant tour of the Internals !!.

Engineer Guy said The Book on Cisco Buffers. This book centers around buffer allocations and buffering problems. It will give you a better understanding of when different buffers are used. I think the title should have been "Cisco IOS Buffering, What you need to know".You definitely have to read between the lines to fill in what all is happening to the data as it flows through the router in different ways. I feel that it is rather limited in it's descriptions of the IOS SW Architecture so don't expect to come away with the full details
Finally, an overview of IOS Quality of Service (QoS) is provided, including descriptions of several QoS methods, such as priority queuing, custom queuing, weighted fair queuing, and modified deficit round robin.. The book then delves into the intricate details of the design and operation of platform-specific features, including the 1600, 2500, 4x00, 3600, 7200, 7500, and GSR Cisco routers. Beyond understanding the Cisco IOS command set, comprehending what happens inside Cisco routers will help you as a network designer or engineer to perform your job more effectively. An essential guide to understanding the Cisco IOS architectureIn-depth coverage of Cisco's IOS Software architecture provides crucial information to: Prevent network problems and optimize performance through more efficient design and configuration Isolate and resolve network problems more quickly and easily Apply the appropriate packet switching method, such as process switching, fast switching, optimum switching, or Cisco Express Forwarding (CEF) Understand the hardware architecture, packet buffering, and packet switching processes for shared memory routers (Cisco 1600, 2500, 3600, 4000, 4500, and 4700 series) Understand the hardware architecture, packet buffering, and packet switching processes for the Cisco 7200 series routers Understand the hardware architecture, packet buffering, and packet switching processes for the Cisco 7500 series routers Understand the ha
