Your business must be connected in order to compete in the global marketplace. Employees need to know that their company's network is accessible at any time, from any place. A Virtual Private Network (VPN) accomplishes this by utilizing remote connectivity technologies that combine existing internal networks with the Internet to securely communicate information. Building a Virtual Private Network is your key to designing, implementing, and securing a fully connected network that meets your business needs.

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.

Learn how to protect your network with this guide to building complete and fully functional network security tools that meet the needs of your company.

The number of models available in neural network literature is quite large. Very often the treatment is mathematical and complex. This book provides illustrative examples in C++ that the reader can use as a basis for further experimentation. A key to learning about neural networks to appreciate their inner workings is to experiment. Neural networks, in the end, are fun to learn about and discover. Although the language for description used is C++, you will not find extensive class libraries in this book. With the exception of the backpropagation simulator, you will find fairly simple example programs for many different neural network architectures and paradigms. Since backpropagation is widely used and also easy to tame, a simulator is provided with the capacity to handle large input data sets. You use the simulator in one of the chapters in this book to solve a financial forecasting problem. You will find ample room to expand and experiment with the code presented in this book.

CCNP Practical Studies: Remote Access (CCNP Self-Study) prepares readers for the CCNP 642-821 BCRAN exam and for workplace challenges in implementing remote access network applications. Designed as a topic-by-topic guide of how to apply remote access concepts in a real network setting, this book is useful in preparing a CCNP candidate for the general exam questions by providing a better understanding of how remote access really works. It is also essential in preparing candidates for the new simulation-based questions that are on the Cisco certification exams. Finally, it serves anyone wanting a guide to real-world application of these concepts, regardless of certification interest.

Becoming a CCSP distinguishes you as part of an exclusive group of experts, ready to take on today's most challenging security tasks. Administration of the Cisco PIX Firewall is a difficult and complex task, critical for protecting a network. Whether you are seeking a PIX-focused certification or the full-fledged CCSP certification, learning what you need to know to pass the Cisco Secure PIX Firewall Advanced (CSPFA) exam will qualify you to keep your company's network safe while meeting business needs.

The Cisco ASA product replaces Cisco PIX Firewalls, and Cisco expert Richard Deal updates his bestselling book, Cisco PIX Firewalls, to cover ASA. This book shows you how to configure and maintain a Cisco ASA appliance to control traffic in the corporate network and protect the network from internal and external threats and attacks. Cisco ASA Configuration covers the latest features available in versions 8.0 and 8.1, and includes detailed examples of complex configurations and troubleshooting. Implement and manage this powerful multifunction network adaptive security appliance with help from this expert guide.

Local-area networks (LANs) are becoming increasingly congested and overburdened because of a dramatic increase in traffic, faster CPUs and operating systems, and more network-intensive applications. Many organizations that use network and computing technology use LAN switching to take advantage of high-speed traffic forwarding and improved performance of traditional Ethernet technologies that don't require costly wiring upgrades or time-consuming host reconfiguration. Cisco LAN Switching Fundamentals provides administrators of campus networks with the most up-to-date introduction to LAN switching within a traditional Ethernet environment.

Each chapter in Cisco Router Firewall Security addresses an important component of perimeter router security. Author Richard Deal explains the advantages and disadvantages of all key security features to help you understand when they should be used and includes examples from his personal consulting experience to illustrate critical issues and security pitfalls. A detailed case study is included at the end of the book, which illustrates best practices and specific information on how to implement Cisco router security features.

Cisco Wireless LAN Security is an in-depth guide to wireless LAN technology and security, introducing the key aspects of 802.11 security by illustrating major wireless LAN (WLAN) standards that can protect the entire network. Because a WLAN is less effective as an isolated piece of the network, this book emphasizes how to effectively integrate WLAN devices into the wired network while maintaining maximum security.

This book is now in its fourth edition. Each edition has corresponded to a different phase in the way computer networks were used. When the first edition appeared in 1980, networks were an academic curiosity. When the second edition appeared in 1988, networks were used by universities and large businesses. When the third edition appeared in 1996, computer networks, especially the Internet, had become a daily reality for millions of people. The new item in the fourth edition is the rapid growth of wireless networking in many forms.

The DNS & BIND Cookbook presents solutions to the many problems faced by network administrators responsible for a name server. This title is an indispensable companion to DNS & BIND, 4th Edition, the definitive guide to the critical task of name server administration. The cookbook contains dozens of code recipes showing solutions to everyday problems, ranging from simple questions, like, "How do I get BIND?" to more advanced topics like providing name service for IPv6 addresses.

End-to-End QoS Network Design is a detailed handbook for planning and deploying QoS solutions to address current business needs. This book goes beyond discussing available QoS technologies and considers detailed design examples that illustrate where, when, and how to deploy various QoS features to provide validated and tested solutions for voice, video, and critical data over the LAN, WAN, and VPN.

This book explores the technical issues underlying local area network (LAN) performance, developing mathematical models that readers can apply to their own specific networking requirements.

Технологія Ethernet останнім часом перестала бути лише технологією, що застосовується при побудові локальних (внутрішньооб’єктових) мереж. Сучасний рівень технології охоплює мережі LAN, WAN та MAN. Сучасне застосування технології Ethernet передбачає роботу на високих швидкостях 1 Гбіт/с, 10 Гбіт/с, використання оптичного волокна, безпосередній вихід на первинну мережу зв’язку, взаємодію технології Ethernet з іншими технологіями мережі доступу (наприклад DSL) та первинної мережі (наприклад SDH, WDM). Автори намагались в цьому посібнику дати опис використання технології Ethernet як в локальних мережах так і на первинній мережі, викласти принципи функціонування технології Ethernet, параметри складових, що входять до мережі, котра використовує технологію Ethernet.
