2 Overview of NonStop TCP/IPv6
This manual documents NonStop TCP/IPv6 only. For information about Parallel Library
TCP/IP, see the TCP/IP (Parallel Library) Configuration and Management Manual.
If run in INET mode (see Table 2-5 on page 2-20), NonStop TCP/IPv6 is a direct
replacement for Parallel Library TCP/IP. (For procedures for running NonStop
TCP/IPv6 in INET mode, see Section 5, Example Illustrations and Adding Features to
the Basic Configuration.)
This manual assumes that you understand IPv6; there is some background information
included in Appendix A, IPv6 Fundamentals as well as in this section, but you are
encouraged to read some of the many excellent resources on IPv6 (see for industry
resources). You do not need to understand IPv6 if you plan to use NonStop TCP/IPv6
in INET mode.
NonStop TCP/IPv6 adds optional IP version 6 (IPv6) functionality to the Parallel Library
TCP/IP product. The NonStop TCP/IPv6 library architecture differs dramatically from
the traditional NonStop TCP/IP process-pair architecture. (In this manual, NonStop
TCP/IP is referred to as conventional TCP/IP.) This section describes the architecture
of NonStop TCP/IPv6 and compares it to conventional TCP/IP.
