Code Introduction

In this chapter, we describe the detailed Mobile Internet Protocol version 6 (IPv6) code implemented as a part of the KAME distribution. The code used in this book is based on the snapshot code generated on July 12, 2004. The code discussed in this book refers to the IPv6 source and destination address fields to access address information, while the information is stored in the ip6_aux{} structure separately in older codes. We believe such inconsistency will not confuse readers in understanding the implementation of Mobile IPv6, since the framework of the KAME code itself has not been modified drastically.

9.1 Statistics

Statistics are stored in the mip6stat{} structure. Table 9-1 describes the statistics variables.
