Title : Public IPv4 over IPv6 Access Network Author(s) : Yong Cui Jianping Wu Peng Wu Olivier Vautrin Yiu L. Lee Filename : draft-ietf-softwire-public-4over6-03.txt Pages : 12 Date : 2012-08-28 Abstract: When the service provider networks are upgraded to IPv6, end users will continue to demand IPv4 connectivity. This document proposes a mechanism for hosts or customer networks in IPv6 access network to build bidirectional IPv4 communication with the IPv4 Internet. The mechanism follows the hub and spokes softwire model, and uses IPv4- over-IPv6 tunnel as basic method to traverse IPv6 network. The bi- directionality of this IPv4 communication is achieved by explicitly allocating public IPv4 addresses to end users, as well as maintaining IPv4-IPv6 address binding on the border relay.
