An essential guide to understanding the Cisco IOS architecture in-depth coverage of Cisco's IOS Software architecture provides crucial information to: Prevent network problems and optimize performance through more efficient design and configurationIsolate and resolve network problems more quickly and easilyApply methods appropriate packet switching, such as process switching, fast switching, optimum 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) to understand the hardware architecture, packet buffering, and packet process switching to routersUnderstand Cisco 7200 series hardware architecture, packet buffering, and packet switching processes for the Cisco 7500 series routersUnderstand hardware architecture, packet buffering, and packet switching processes for the Cisco GSR 12000 series routersFurther your knowledge of how to implement IOS Software Quality of Service ( QoS) Inside Cisco IOS Software Architecture offers crucial and hard to find information about Cisco Internetwork Operating System (IOS) Software. Beyond understanding the Cisco IOS command set, to understand what is going on inside Cisco routers will help you as a network designer or engineer to perform your job more effectively. Inside Cisco IOS Software Architecture provides essential information about the internal aspects of IOS Software at this level, and it are an invaluable resource for better understanding the intricacies of IOS Software and how it affects your network. Inide Cisco IOS Software Architecture begins with a picture of the operating system concepts and the IOS Software infrastructure, including processes, memory management, CPU scheduling, packet buffers, and device drivers, as well as a discussion of packet switching architecture with detailed coverage of various platform-independent switching methods, including process switching, fast switching, optimum, and Cisco Express Forwarding (CEF).
