Dieses hochaktuelle Buch erklärt IPv6 mit all seinen neuen Features und erweiterten Funktionalität im Detail. Es wendet sich an einen breiten Kreis von Fachleuten. Egal ob Sie ein System- oder Netzwerkadministrator, ein System- oder Netzwerkengineer, ein Netzwerk-Designer oder ein IT Manager sind, in diesem Buch finden Sie das Wesentliche über IPv6. Das vermittelte Wissen hilft Ihnen IPv6 in Ihrer Strategie zu positionieren, die Integration von IPv6 in Ihre IPv4 Infrastruktur zu planen und gibt zahlreiche Anleitungen und Tipps wie Sie eine Testumgebung einrichten können oder sich an globalen Testnetzen beteiligen können. Das Buch bespricht den neuen IPv6 Header, ICMPv6, Autoconfiguration, IPv6 Routing Protokolle, Interoperability- und Transitionsmechanismen und last but not least enthält es ein Kapitel das beschreibt, wie man auf verschiedenen Betriebssystemen IPv6 installiert.

This book is about the next generation Internet protocol. We have become familiar with the strengths and weaknesses of IPv4; we know how to design and configure it, and we have learned to troubleshoot it. And now we have to learn a new protocol? Start from scratch? Not really. The designers of IPv6 have learned from over 15 years of experience with IPv4 and they have been working on the new protocol since the early 90s. They retained the strengths of IPv4, extended the address space from 32-bits to 128-bits, and added functionality that we are missing in IPv4 today. They developed transition mechanisms that make IPv4 and IPv6 coexist peacefully and that guarantee a smooth transition. In fact this has been one of the major requirements for the development of the new protocol version. This book covers all you need to know to become familiar with IPv6 - you will love it.


Who should read this book?top
This book covers a broad range of information about IPv6 and is an excellent resource for anybody who wants to understand or implement the protocol. This book is for system and network administrators, engineers, network designers, and IT managers. If you need to plan your corporate strategy for IPv6 you will be most interested in chapters 1, 4, 9 and 10. If you are a system or network administrator, all chapters are relevant: this book provides a foundation for IPv6 implementation and integration with IPv4. If you manage the infrastructure in your company you will especially be interested in the Chapters 7 and 8, which cover Layer 2 issues and routing, and Chapter 10, which addresses interoperability.

Chapter 1, IPv6 versus IPv4
This chapter shortly explains the history of IPv6, gives an overview of the new functionality and describes some live test- and production-networks that are already using IPv6.

Chapter 2, The Structure of the IPv6 Protocol
This chapter describes the new IPv6 header format, with a discussion of each field and a trace file example. It also describes what Extension Headers are, what types of Extension Headers have been defined, and how they are used.
Chapter 3, IPv6 Addressing
This chapter explains everything you need to know about the new address format, address notation, address types, international registry services, and prefix allocation.
Chapter 4, ICMPv6
This chapter describes the new ICMPv6 message format, the IMCPv6 Error messages and available Informational Messages, the ICMPv6 header in a trace file, and discusses the extended functionality based on ICMPv6 such as Neighbor Discovery, Autoconfiguration, Path MTU Discovery, and Multicast Group Management. You will learn how ICMPv6 makes administration easier.
Chapter 5, Security in IPv6
This chapter begins with a short discussion of basic security concepts, requirements, and current solutions. It then covers the IPSEC framework, security elements available in IPv6 for authentication and encryption, how they are used and how they integrate with other elements such as NAT routers and autoconfiguration.
Chapter 6, Quality of Service in IPv6
This chapter discusses basic requirements and types of QoS. QoS elements available in IPv6 and how they can be implemented are explained. It also describes different QoS architectures and introduces further work in this area, primarily on resource reservation.
Chapter 7, Networking Aspects
This chapter discusses Layer 2 support for IPv6 (Ethernet, Token Ring, ATM, Frame Relay etc), explains multicast support and multicast routing, Mobile IPv6, and discusses some sample network designs that show how IPv6 can grow into our networks step-by-step without interruption of our IPv4 services.
Chapter 8, Routing Protocols
This chapter discusses the advanced routing features with IPv6 and covers the available routing protocols such as RIPng, OSPFv3 for IPv6, BGP extensions for IPv6, IS-IS, and EIGRPv6.
Chapter 9, Upper Layer Protocols
This chapter discusses what is going on above the IP layer, starting with changes for TCP and UDP, and continuing with DHCPv6, DNS extensions for IPv6, SLPv2 in IPv6 networks, FTP, Telnet and Web servers.
Chapter 10, Interoperability
This chapter discusses the different transition mechanisms that have been defined, such as dual-stack operation, tunneling and translation techniques, and shows how they can be used and combined in order to ensure peaceful coexistence and smooth transition. It also provides a list of vendor links to find out what equipment, stacks and software is available currently.
Chapter 11, Get your Hands Dirty
This chapter explains how to get started with IPv6 on different operating systems such as Sun Solaris, Linux, Windows 2000 and Windows XP, and on a Cisco router. It also explains what I did in my lab and provides examples of trace files.

The Appendix gives a short introduction to the RFC process and authorities, and provides a list of relevant RFCs for IPv6. The Appendix reflects the chapter organization of the book and provides summaries of all indexes, protocol numbers, messages types, address allocations. The Appendix is your best place for getting quick information if you are configuring or troubleshooting IPv6.
