"IPv6 Core Protocols Implementation addresses with technical depth and clarity an IPv6 implementation on University California Berkeley Source Code Distribution (BSD), from the KAME project that was based in Japan, which is both a commercial and academic success in the world wide networking implementation market. The book begins with an overview of the KAME project and source code distribution, and then provides a concise, but thorough overview of the BSD network implementation. Then the book provides the architecture and an implementation code base component for IPv6 added to the current BSD TCP/IP Internet Protocol layer code base, the implications of the changes to the Transport Layer, and then provides a review of the BSD Socket Application Interface changes for IPv6. The authors did a very good job of representing the source code implementation and it was easy to read and comprehend, with discussion for each programmatic presentation of the code base functions and data structures. This book will be valuable to both networking architects and programmers that have to absorb and understand the implementation of IPv6 within the TCP/IP network implementation and reference model. The book was a pleasure to read and reminded me of the TCP/IP technical books by the late Dr. Richard Stevens, and afforded me the same technical depth." -Jim Bound, CTO IPv6 Forum www.ipv6forum.com
