The IESG has approved the following document: - 'Delivery of IPv4 Multicast Services to IPv4 Clients over an IPv6 Multicast Network' (draft-ietf-softwire-dslite-multicast-18.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-dslite-multicast/ Technical Summary This document defines a mechanism for transporting IPv4 multicast traffic over single-stack IPv6 multicast service provider's networks. This is achieved through the use of the underlying IPv6 multicast distribution tree. The IPv4 traffic is statelessly encapsulated in IPv6. The main benefit of this solution is using an IPv6 multicast network for the efficient distribution of IPv4 based multicast content. Working Group Summary There is consensus in the WG for the publication of this document. WGLC was originally completed in 2012, but the document has been delayed in progressing due to higher priority WG documents. Document Quality An implementation was demoed at IETF82 which showed interworking between a vendor's implementation of the mAFTR and a mB4 implementation. An open source based implementation of the mB4 function is available. Personnel Softwire co-chair, Ian Farrer, is the Document Shepherd. Terry Manderson is the Responsible AD.
