This document captures the problem statement for the
Softwires
Working Group, which is developing standards for the
discovery,
control, and encapsulation methods for connecting IPv4
networks
across IPv6-only networks as well as IPv6 networks across
IPv4-only
networks.  The standards will encourage multiple,
inter-operable
vendor implementations by identifying, and extending where
necessary,
existing standard protocols to resolve a selected set of
"IPv4/IPv6"
and "IPv6/IPv4" transition problems.  This
document describes the
specific problems ("Hubs and Spokes" and
"Mesh") that will be solved
by the standards developed by the Softwires Working Group. 
Some
requirements (and non-requirements) are also identified to
better
describe the specific problem scope.  This memo provides
information for 
the Internet community.

This document is a product of the Softwires
Working Group of the IETF.
