A New Internet-Draft is available from the on-line
Internet-Drafts
directories.
This draft is a work item of the Softwires Working Group of
the IETF.
Title : Softwire Mesh Framework
Author(s) : J. Wu, et al.
Filename : draft-ietf-softwire-mesh-framework-01.txt
Pages : 32
Date : 2007-6-8
The Internet needs to be able to handle both IPv4 and IPv6
packets.
However, it is expected that some constituent networks of
the
Internet will be "single protocol" networks.
One kind of single
protocol network can parse only IPv4 packets and can
process only
IPv4 routing information; another kind can parse only
IPv6 packets
and can process only IPv6 routing information. It is
nevertheless
required that either kind of single protocol network be
able to
provide transit service for the "other"
protocol. This is done by
passing the "other kind" of routing information
from one edge of the
single protocol network to the other, and by tunneling
the "other
kind" of data packet from one edge to the other.
The tunnels are
known as "Softwires". This framework document
explains how the
routing information and the data packets of one protocol
are passed
through a single protocol network of the other protocol.
The
document is careful to specify when this can be done with
existing
technology, and when it requires the development of new
or modified
technology.

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.
