Abstract

This document captures the problem statement for the SoftwiresWorking Group, which is developing standards for the discovery,control, and encapsulation methods for connecting IPv4 networksacross IPv6-only networks as well as IPv6 networks across IPv4-onlynetworks. The standards will encourage multiple, inter-operablevendor 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 thespecific problems ("Hubs and Spokes" and "Mesh") that will be solvedby the standards developed by the Softwires Working Group. Somerequirements (and non-requirements) are also identified to betterdescribe the specific problem scope. This memo provides information for the Internet community.
