Dual-Stack lite (DS-lite) has been proposed as an IPv4 to IPv6
transition technique. Dual-stack lite allows a service provider to
migrate his network to IPv6, while still offering IPv4 services to
the customer. The dual-stack lite solution uses an IPv4-over-IPv6
tunnel between a host (or access device) and a dual-stack lite
Carrier Grade NAT (CGN). Several existing network architectures
(e.g. 3GPP, WiMAX, or PPP based broadband networks) already specify
dual-stack deployment and leverage tunneling schemes between the
access device and an access gateway in the provider network.
Applying the dual-stack lite concept to these networks will result in
changes to the end-system and unnecessary tunneling overhead. This
draft describes a modified implementation of dual-stack lite where
existing access tunnels are extended beyond the access gateway to the
dual-stack lite CGN using softwires. This evolved approach not only
applies to IPv6 networks but also includes support for IPv4 networks.
