Mobile IP Technology and Applications Review by Penny Jakes
Mobility vs. Nomadicity
Mobile IP Technology and Applications (ISBN 158705132x) is an introduction to IP mobility using an open-standard protocol called Mobile IP. There is a distinction made between true mobility and just "traveling" between different connections. This protocol enables users to keep their IP, stay connected, and allow others to find them while roaming between networks and equipment. In addition, detailed examples using real-world situations illustrate the applications of this technology. Advanced topics include reverse tunneling, firewalls, NAT, VPNs, authentication, scalability, and QoS.
Stefan Raab and Madhavi W. Chandra, authors, share their experience designing and developing network solutions using Mobile IP. Their credentials are impressive and give the learner confidence in the information they are imparting.
This book is designed for network administrators who are familiar with IP routing, protocols, applications, and Cisco IOS. Even though the real-world situations are generic, the configuration, troubleshooting, and management are explained using Cisco IOS. IT personnel who want to implement mobile technology can definitely benefit from this book as it explains the basics thoroughly before giving detailed examples and explanations. The index is complete; there is not a glossary. At the end of each chapter are review questions, so this book could easily be used in a classroom or in self-study. There are two appendices: one contains the answers to the chapter questions and the other contains the SNMP (Simple Network Management Protocol) MIB (Management Information Base) objects supported by Cisco IOS Mobile IP.
Raab and Chandra organized their book into nine chapters, each of which is a facet of Mobile IP. After an introduction of concepts and requirements of mobility and wireless networking, a detailed discussion of the Mobile IP protocol includes features, functions, and components. As with any network today, there are security concerns with protocol authentication and dynamic keying. The material presented in these early chapters is used in the scenarios in following chapters.
Mobility solution examples are provided for basic topologies, client-based Mobile IP, high availability, AAA servers, reverse tunneling, firewall and NAT traversal, and integration with VPN technologies. Basic configuration is introduced which leads into integration topics of redundancy, QoS, and VPN. The management and operation discussion leads to Home Address, scalability, and server management.
Future trends and uses for Mobile IP conclude the topics of this book: layer 2 integration challenges, Mobile IPv6, unstructured mobility, and ad hoc networking.
This book follows the linear, logical model of textbook organization that progresses from basic facts, to advanced topics, and concludes with end-to-end solutions. The authors feel that this book also enables someone to jump in at any chapter and navigate the subject by features and environment in which they are interested. They have created cross-references to assist readers who do not want to use the book in linear form. This works well for users with previous knowledge of the subject.
The examples, figures, and illustrations are clear, concise, and designed to help learners understand a complex subject. Cisco IOS knowledge is prerequisite, although the authors' expertise and explanations give logic behind implementation and options.
This book deserves a rating of 5 (highest) and is recommended for IT personnel wanting to move into true "mobility."
