Inhaltsangabe

Today, organizations are more dependent on their Cisco networks than ever before -- and their networks are growing ever more complex and interdependent. In this book, one of the world's leading network consultants shares practical, realistic techniques for maximizing reliability and availability in any network environment. This book discusses every leading approach to improving network availability, including key principles and tradeoffs -- guiding network professionals in choosing the most appropriate solutions for their own networks. Leading network consultant, Dr. Vincent Jones presents a series of common network scenarios, analyzes their weaknesses, and presents solutions -- demonstrating how to ensure that other services continue unaffected when parts of the network fail, and how to automate recovery. While the examples in the book are Cisco-focused, the principles and design tradeoffs apply to any contemporary router- or switch-based internetwork. For every network designer and administrator responsible for optimizing the reliability and availability of today's networks.

Von der hinteren Coverseite

Keeping a network continuously available despite the many potential hazards that can shut it down is a job that network implementors and technical managers struggle with every day. High Availability Networking with Cisco shows those charged with that increasingly important task how to achieve higher network availability both in theory and in practice. Using a "divide-and-conquer" approach, each chapter dissects the general need of high availability network design. The specific challenges and available solutions for each need are first discussed on a theoretical level. When appropriate, one or more implementation examples are presented, showing how the theory translates into working Cisco router configurations.

Although the examples use Cisco routers, the underlying theory is vendor-independent, and most of the solutions presented easily can be adapted to routers and switches from any vendor. Similarly, the theoretical aspects discussed in this book can be applied to networks of all sizes and technologies. Sample solutions focus on the needs of moderately sized extended corporate networks using IP version 4.0 and stable performance technologies such as frame relay, ISDN, and Ethernet.

Readers will find an invaluable survey of all aspects of high availability network design, including the following:

• Network vulnerabilities and appropriate counter measures
• Selecting and tuning bridging and routing protocols for higher availability
• Multihomed hosts from individual client-to-server clusters
• Dial backup over asynchronous and ISDN links
• Single points of failure despite multiple routers at a single site
• Hub and spokes design approaches that scale
• Linking to another private network
• Multiple links to one or more Internet service providers
• Alternate routing through redundant firewalls without sacrificing security
• Supporting legacy systems using Data Link Switching (DLSw)
• Disaster-recovery options, including hot backup and load sharing approaches
• Management considerations ranging from status monitoring to total quality control

By using many examples drawn from working configurations proven to be successful in actual corporate networks, High Availability Networking with Cisco reflects the author's extensive experience helping clients minimize the impact of failure on network operations
