Synopsis

This volume of the Network Troubleshooting Library presents practical information on how to implement IP (Internet Protocol) Version six, using case studies and examples that illustrate how IPv6 operates and the steps needed to implement the transition from the current IPv4 to IPv6. The accompanying CD-ROM contains RFCs that describe, define and document IPv6 standards and related protocols, plus transition mechanisms and strategies.

"The IPv6 Specification

The IPv6 specification is defined in RFC 1883 [2-2], with additional work that documents proposed enhancements to these efforts [2-3]. RFC 1883 summarizes the following changes from IPv4 to IPv6:

* Expanded Addressing Capabilities--Increasing the address size from 32 bits to 128 bits, supporting more levels of address hierarchy, many more addressable nodes, scalable multicast addresses, plus the "anycast" address, which is used to send a packet to any one of a group of nodes.
* Header Format Simplification--Eliminating or making optional some of the header fields, thus reducing the protocol processing overhead of the IPv6 header.
* Improved Support for Extensions and Options--Including more efficient forwarding, less stringent limits on the length of options, and greater flexibility for future options.
* Flow Labeling Capability--A new function which enables packets that belong to a particular traffic "flow" to be labeled for special handling.
* Authentication and Privacy--Extensions to support authentication, data integrity, and optional data confidentiality.

In order to support these design changes, the structure of the IPv6 packet varies somewhat from its predecessor, IPv4. First of all, fields that were seldom used have been eliminated. Second, fields that provide a specific function have been removed from the base header and placed in optional extension headers. In this way, the extension header or headers are only added when required by a specific protocol function, such as fragmentation or packet routing. There is also a recommended order for these extension headers, such that headers that are only germane to the end-to-end host process need not be examined by every router along the way. The next section will explore the IPv6 base header and all of the extension headers in detail."
