@chapter Introduction

The primary means of networked communications
for GigaMos (formerly LMI) Lambda systems
is through the Ethernet@tm@ -based communications software protocols,
TCP/IP and Chaosnet.
Release 4.0 LISP of ZetaLISP-Plus@tm@ includes fundamental revisions to
the LISP product implementations of TCP/IP and Chaosnet.

This manual accompanies the @i(4.0 LISP Release Notes),
which should be read first.
The first part describes changes in functionality,
installation, configuration, and operating procedures.

The major changes are in the following areas,
each of which is covered by a separate chapter:

@itemize @bullet
@item @nameref[chapter-architecture]  [@i(@ref[chapter-architecture])]
@item @nameref[chapter-installation] [@i(@ref[chapter-installation])]
@item @nameref[chapter-configuration] [@i(@ref[chapter-configuration])]
@item @nameref[chapter-operating] [@i(@ref[chapter-operating])]
@item @nameref[chapter-tcp-app] [@i(@ref[chapter-tcp-app])]
@item @nameref[chapter-limitations] [@i(@ref[chapter-limitations])]
@end(itemize)

Following the installation of 4.0 LISP software,
the Lambda system manager should execute the network configuration procedures
documented here.

@textbox
To provide properly functioning networking software,
you (or the Lambda system manager at your site)
@i(must) read this manual carefully and
perform the required site file modifications which are documented below.
@end(textbox)

The second part of this manual contains general information on LISP networking software and
follows the general structure of the release notes,
but amplifies that material to provide comprehensive documentation.
These chapters include new information not previously documented,
as well as information gathered from earlier manuals:

@itemize @bullet
@item @nameref[chapter-doc-architecture]  [@i(@ref[chapter-doc-architecture])]
@item @nameref[chapter-doc-configuration] [@i(@ref[chapter-doc-configuration])]
@item @nameref[chapter-doc-operating] [@i(@ref[chapter-doc-operating])]
@item @nameref[chapter-doc-generic-applications] [@i(@ref[chapter-doc-generic-applications])]
@item @nameref[chapter-doc-tcp-app] [@i(@ref[chapter-doc-tcp-app])]
@item @nameref[chapter-doc-programs] [@i(ref[chapter-doc-programs])]
@end(itemize)

Appendix @ref[appendix-unix] documents the networking software available with
the (optional) Lambda-Plus 68010 processor running System 5 Unix.

Lambda system managers experienced with release 3 may be able to make the necessary
configuration changes after reading
Chapter @ref[chapter-configuration], @b(@nameref[chapter-configuration]).
Others (including system managers with new Lambda systems)
should proceed to
Chapter @ref[chapter-doc-configuration], @b(@nameref[chapter-doc-configuration]),
which fully documents the configuration process.

Users of previous releases should read
Chapter
@ref[chapter-operating],
@b[@nameref(chapter-operating)]
for information on functions that have changed.
Complete operating information is provided in
Chapter @ref[chapter-doc-operating], @b(@nameref[chapter-doc-operating]),
and subsequent chapters.
