IPv6 Essentials

zkstone

IPv6, the next generation Internet Protocol, has been in the works since the early 90s when the rapid growth of the Internet threatened to exhaust existing IP addresses. Drawing on 20 years--operational experience with the existing protocol (IPv4), the new protocol offers scalability, increased security features, real-time traffic support, and auto-configuration so that even a novice user can connect a machine to the Internet. But what does this mean for IT professionals? Having learned all the strengths and weaknesses of the old protocol, will you need to start from scratch with the new? IPv6 Essentials provides a succinct, in-depth tour of all the new features and functions in IPv6, guiding you through everything you?ll need to know to get started, including how to configure IPv6 on hosts and routers, and which applications currently support IPv6. Aimed at system and network administrators, engineers, network designers, and IT managers, this book will help you plan for, design, and integrate IPv6 into your current IPv4 infrastructure. Beginning with a short history of IPv6, author Silvia Hagen provides an overview of the new functionality and describes some live test and production networks that are using the new protocol. Hagen then shares exhaustive discussions of the new IPv6 header format and Extension Headers, IPv6 address format, and IPv6 message format.

90年代初期,由于互联网的高速发展,现存的IP地址有了被耗尽的危险,因此,IPv6,下一代互联网协议，开始运作。借鉴20年来 - 现有协议（IPv4）的运作经验，新的协议提供了扩展性，增强的安全功能，实时传输和自动配置等特点，即便是初级用户也可以连接一台机器到网络上。但是，这对IT专业人士又意味着什么呢？既然已经了解了旧协议所有的优势和缺陷，是否还有必要从头开始学习新的协议？ IPv6的精华>一书简洁而又不失深度的遍历了IPv6的所有特点和功能,给出了开始学习一个新协议所需的一切,包括如何在主机与路由器上配置IPv6，目前哪些应用程序支持IPv6等。针对系统和网络管理员，工程师，网络设计师和IT经理，这本书将帮助您规划，设计和集成IPv6到你当前的IPv4基础设施。由介绍IPv6的简短历史开始，作者Silvia Hagen提供了新功能的概述，并介绍了一些正在使用新的协议的现场测试和运行网络。之后Hagen详尽讨论了，新的IPv6报头格式与扩展头部，IPv6地址格式和IPv6的消息格式。
