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.
