  "abstract": "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.",
