A New Internet-Draft is available from the on-line Internet-Drafts
directories.
Title : Advanced Sockets API for IPv6
Author(s) : W. Stevens, M. Thomas
Filename : draft-stevens-advanced-api-00.txt
Pages : 31
Date : 10/21/1996
Specifications are in progress for changes to the sockets API to support IP
version 6 [1]. These changes are for TCP and UDP-based applications and
will support most end-user applications in use today: Telnet and FTP
clients and servers, HTTP clients and servers, and the like.
But another class of applications exists that will also be run under IPv6.
We call these "advanced" applications and today this includes programs such
as Ping, Traceroute, routing daemons, multicast routing daemons, router
discovery daemons, and the like. The API feature typically used by these
programs that make them "advanced" is a raw socket to access ICMPv4,
IGMPv4, or IPv4, along with some knowledge of the packet header formats
used by these protocols. To provide portability for applications that use
raw sockets under IPv6, some standardization is needed for the advanced
API features.
There are other features of IPv6 that some applications will
need to access: interface identification (specifying the outgoing interface
and determining the incoming interface) and IPv6 extension headers that are
not addressed in [1]: hop-by-hop options, destination options, and the
routing header (source routing).

Internet-Drafts are also available by mail.
Send a message to: mailserv@ds.internic.net. In the body type:
"FILE /internet-drafts/draft-stevens-advanced-api-00.txt".
NOTE: The mail server at ds.internic.net can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e., documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
