The IESG has approved the following document: - 'Unified IPv4-in-IPv6 Softwire CPE: A DHCPv6-based Prioritization Mechanism' (draft-ietf-softwire-unified-cpe-08.txt) as Proposed Standard This document is the product of the Softwires Working Group. The IESG contact persons are Suresh Krishnan and Terry Manderson. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-softwire-unified-cpe/ Technical Summary In IPv6-only provider networks, transporting IPv4 packets encapsulated in IPv6 is a common solution to the problem of IPv4 service continuity. A number of differing functional approaches have been developed for this, each having their own specific characteristics. As these approaches share a similar functional architecture and use the same data plane mechanisms, this memo describes a specification whereby a single CPE can interwork with all of the standardized and proposed approaches to providing encapsulated IPv4 in IPv6 services. Working Group Summary This document was discussed in depth and well-reviewed. The WG achieved the consensus to publish this document. Document Quality There are currently no known implementations, however an operator/vendor has one scheduled for development later this year. Personnel Yong Cui, is the Document Shepherd. Terry Manderson is the Responsible AD. IANA Note This document needs IANA to assign a new DHCPv6 option code OPTION_V6_S46_PRIORITY.
