Title : IPv4 Path Based Routing
Author(s) : D. Mao
Filename : draft-mao-ipv4-path-routing-00.txt
Pages : 12
Date : 2004-11-23
This document describes a solution to the IPv4 address shortage
problem. The solution is to be implemented within the IPv4
framework, rather than inside a "next generation" IP protocol.
By organizing local networks as an "intranet hierarchy" attached
to the Internet, nodes inside the hierarchy can be uniquely addressed
with path descriptions. Two IPv4 options, Source-Side Path-info and
Destination-Side Path-info, are added into the IPv4 protocol, so that
up to 2 path descriptions can be carried in the IPv4 header. Further,
a currently unused flag bit in the IPv4 header is used to extend the
logical IPv4 header, so that options can also be carried "out-band".
Core routers in the Internet will ignore the unrecognized new options
and the extension, and thus need not be replaced or updated.

In the body type:
"FILE /internet-drafts/draft-mao-ipv4-path-routing-00.txt".
NOTE: The mail server at ietf.org 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.
