Description

This book contains important information for practical applications on the operating system of routers Cisco - Internetwork Operating System (IOS). IOS software provides the means by which networking professionals configure Cisco devices and manage them. Understanding the structure of commands Cisco IOS, as well as the understanding of what is happening inside the router will help you as a designer or a network administrator to do their job more effectively. Knowledge of the inner workings of the operating system IOS will help you take into account the subtleties of the hardware structure of the necessary devices in the process of developing the network, as well as facilitate troubleshooting in the future. This book contain all the necessary information ovnutrenney structure OS IOS.
This book begins with an overview of the basic concepts of operating systems and infrastructure review OS IOS: processes, memory management, task scheduler, packet buffers, and device drivers. Then more podrobnorassmatrivayutsya different device-dependent switching methods: software switching, fast switching, optimum switching and protocol Cisco Express Forwarding (CEF). You also get to know the features of the hardware implementation of the principles and rabotyrazlichnyh platforms, namely the units of the series 1600, 2500, 4x00, 3600, 7200.7500 and Series Routers Cisco GSR. The book ends with the description of technologies QoS, and information on the different methods of implementing quality of service: the order of priority, weighted fair queuing, custom line method and mechanism of changes cyclically deficit.
- Prevent the occurrence of problems in the network and optimize its performance due to a more rational design and configuration
- Isolate and resolve the problem in a network the fastest and most effective way
- Use the most appropriate method for your network packet switching: soft switching, fast switching, optimum switching and CEF
- Examine osobennostiapparatnoy structure buffering packets and packet switching techniques in routers shared memory (the Cisco 1600 Series, 2500, 3600, 4000, 4500. 4700)
- Examine the hardware features of the structure, packet buffering, and packet switching techniques in the Cisco 7200 Series
- Examine the hardware features of the structure, the structure of VIP cards and methods of packet switching in the Cisco 7500 Series
- Examine the hardware features of the structure, packet buffering, and packet switching techniques in the Cisco 7200 Series GSR
- Expand your knowledge about the methods of implementation of the technology quality of service (QoS) Cisco IOS
This book is a series of Cisco CCIE Professional Development, which gives professionals the information chain to build a real existing networks, understanding new technologies and successful management of networks of any complexity and will wave to prepare for the certification exam CCIE.
The program CCIE and Cisco Press
Cisco's efforts on the preparation of competent professionals for network operating center (NOC) and professionals in the field of information technology (IT) implemented in the framework of the Cisco Certified Internetwork Expert (CCIE). In order to develop this program, Cisco Press is actively cooperating with the management of CCIE program in the field of information products that would help broaden and deepen the knowledge of experts in the field of IT, as well as provide the latest and most accurate information about modern technologies, knowledge of which is necessary for professionals CCIE.
Publications CCIE Professional Development Series is based on the basic principles of the program CCIE. This series consists of books describing the specific technologies that are needed for those who are planning to get a certificate CCIE, and for IT professionals.
