The document describes a new transition methodology for the BD-SIIT IPv4/IPv6 translation technique using forward and feedback address mapping algorithms. The methodology aims to reduce packet size and traffic overhead compared to tunneling algorithms, and reduce the cost of IPv6 networks by avoiding the need to upgrade all edge nodes. It proposes using a new address mapping that identifies two public addresses instead of the IPv4 mapped IPv6 address method.
